Ranges may be expressed herein as from “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. 
     In example embodiments, the present invention provides a kettle bell and methods of using the kettle bell. According to one example embodiment, the invention includes a kettle bell comprising a weighted base portion, a grasping handle extending from the base portion for receiving one or more hands of the user or lifter, and a conduit or opening extending through the base portion. In example embodiments, the opening of the base portion is generally cylindrical in shape, and is generally sized for receiving an end collar member of a barbell. Optionally, the opening generally extends entirely through at least a portion of the weighted member, and is shaped as desired (e.g., hexagonal, polygonal, triangular, oval, etc.). 
     With reference now to the drawing figures, wherein like reference numbers represent corresponding parts throughout the several views,  FIG.  1    shows a kettle bell  10  according to an example embodiment of the present invention. As depicted, the kettle bell  10  comprises a generally spherical shaped weighted mass or object  12 , with a generally flat bottom  14  for resting atop a support surface SS, and a handle  20  extending from an upper portion of the mass  12  to form a loop-like grasping ring  22 . In alternate example embodiments, the weighted mass or object  12  can be shaped as desired. In example embodiments, an opening  24  is defined between the ring  22  and the upper portion of the mass  12 . In preferred example embodiments, an opening  30  extends entirely through a generally central area of the mass  12 , for example, to provide for accommodating interengagement with the end male receivers or collar ends CE of a barbell B. For example, as depicted in  FIGS.  2 - 3   , each of the collar ends CE of the barbell B are engaged with two kettle bells  10 , for example, to provide an alternative option for adding additional weight to the collar ends CE of the barbell B, for example, rather than utilizing standard plate or disc-shaped weights. According to example embodiments, the barbell B with one or more of the kettle bells  10  removably engaged at each collar end CE can be used by the user, for example, to perform dead lift exercises, or for example, a bench-type chest exercise, a shoulder press exercise, or additional types of exercises as desired. 
     In example embodiments, the collar ends CE of the barbell comprise a diameter of about 50 millimeters or about 2 inches, and the opening  30  comprises a diameter that is at least partially larger than the collar end CE diameter such that the collar end CE can slidingly engage with the opening  30 . In some example embodiments, the opening can be substantially larger than the diameter of the collar end CE, and one or more frictional pads or inserts can be provided for allowing a generally tight-fitting engagement. Optionally, a rubber sleeve can be provided on the collar ends CE, and the opening  30  is generally sized to fit over the rubber sleeve. 
     As depicted in  FIG.  1   , the opening  30  is generally formed through the entirety of at least a portion of the mass  12 . In example embodiments, the opening  30  is generally positioned at least partially above the center of mass CM of the kettle bell  10 . As such, when the kettle bell  10  is removably mounted to the collar end CE, the kettle bell  10  remains oriented upright (due to the center of mass CM being positioned below the center of the opening  30 ), for example, such that the bottom  14  remains generally parallel with the support surface SS. 
       FIG.  4    shows a kettle bell  100  according to another example embodiment of the present invention. As depicted, the kettle bell  100  is substantially similar to the kettle bell  10  as described above. For example, the kettle bell  100  generally comprises a generally spherical shaped weighted mass or object  112 , with a generally flat bottom  114  for resting atop a support surface SS, and a handle  120  extending from an upper portion of the mass  112  to form a loop-like grasping ring  122 . Similarly, an opening  130  extends entirely through the mass  112 , for example, such that the center of the opening  130  is generally positioned at least partially above the center of mass CM of the mass  112 . According to example embodiments, a retaining mechanism or stop member  150  is provided with the mass  112 , which comprises a central shaft  152  extending between an adjustment portion  154  and an engagement portion  156 . In example embodiments, the adjustment portion  154  can be rotated about axis X, which provides for translation (up and down) of the engagement portion  156  into and out of the opening  130 . For example, after the collar end CE is fitted through the opening, the adjustment portion  154  can be rotated to cause frictional engagement of the engagement portion  156  with an outer periphery of the collar end CE. Thus, the retaining mechanism  150  preferably provides for securing the kettle bell  100  to the collar end CE, thereby preventing the kettle bell  100  from unintentional disengagement from the collar end CE during use. In some example forms, the engagement portion  156  is generally curved or radiused to follow the curvature of the opening  130 , for example, such that in a fully retracted position, the collar end CE is slidably engageable with the opening. Further, when the engagement portion  156  is in an engaged position, the curved surface of the engagement portion  156  is generally substantially frictionally engaged with an outer periphery portion of the collar end CE. Optionally, the engagement portion  156  can be shaped as desired for providing engagement with the collar end CE. Optionally, other retaining mechanisms, fasteners, coupling members, etc. can be used as desired, for example, to provide for removably attaching the kettle bell  100  to the collar end CE. In example embodiments, the engagement portion can be formed from a rubber or high friction material, for example, for increasing the frictional engagement with the outer periphery of the collar end CE. 
       FIG.  5    shows a kettle bell  200  according to another example embodiment of the present invention. As depicted, the kettle bell  200  is substantially similar to the kettle bell  10  as described above. According to one example form, the grasping handle or ring  222  is preferably sized and shaped such that the opening  224  that is defined between the ring  222  and the mass  212  can receive the collar end CE. Thus, rather than removable attachment of the kettle bell with the collar end CE by providing an opening within the mass, the opening  224  defined between the ring  222  and the mass  212  is sized and shaped to receive the collar end CE or to be grasped by one or more hands us a user. Preferably, one or more retaining members, fasteners, couplings, etc. can be provided for removably securing the kettle bell  200  to the collar end CE. 
       FIGS.  6 - 8    show a kettle bell according to another example embodiment of the present invention. As depicted, the kettle bell  300  is substantially similar to the kettle bell  10  as described above. In example embodiments, an opening  330  extends entirely through an upper portion of the mass  312 , which provides for receiving the collar end CE of the barbell B. In example embodiments, the opening  330  is positioned substantially above the center of mass CM of the mass  312 . In example embodiments, the center of the opening  330  is generally configured to be at least partially below the outer peripheral surface of the mass  312 . Thus, the opening  330  defines a U-shaped channel, which is at least partially more than half of a circle (e.g., greater than 180 degrees) such that the collar end CE is prevented from disengaging the kettle bell  300  during use. Accordingly, the collar end CE is permitted to slidingly engage with the opening  330  of the kettle bell  300  during attachment or detachment thereof, however, as the opening  330  is generally at least partially greater than 180 degrees, the collar end CE is incapable from disengaging the opening  330  during use (e.g., lifting the barbell B when one or more kettle bells  300  are removably attached). According to one example embodiment, a clasp or fastener  350  can be provided for further securing the collar end CE to the kettle bell  300 , or for example, for further securing the kettle bell  300  to the collar end CE. 
     In example embodiments, the kettle bell  10  is generally formed from a cast iron material, or can optionally be formed with other dense metals or other materials, sand, etc. Preferably, the total weight of the kettle bell  10  is generally between 5-115 lbs. According to some example embodiments, the kettle bell  10  can be configured to be weighted generally similar to known disc-shaped weights, for example, between about 5-45 lbs. Optionally, as described above, the kettle bell  10  can be weighted as desired, for example, which can be more than 45 lbs. 
     According to another example embodiment, the present invention relates to a method of using a kettle bell for exercising. The method includes providing a kettle bell, the kettle bell comprising a generally spherical shaped weighted mass, a generally flat bottom for resting atop a support surface, a handle extending from an upper portion of the mass to form a loop-like grasping ring, and an opening extending entirely through a generally central area of the mass; grasping the kettle bell with one or more hands of a user; performing one or more exercises; providing a barbell comprising male collar end receivers; removably attaching a kettle bell to each of the collar end receivers, wherein the collar end receivers are fitted through the opening of each kettle bell; and performing one or more exercises by grasping and lifting the barbell. 
     According to another example embodiment, an engagement clasp, ring, or other connector can be provided, for example, for removably attaching the kettle bell to the collar end of the barbell. For example, rather than engaging the collar end CE with an opening formed through the mass or through the opening defined between the grasping ring and the mass, a separate attachment ring or coupling member can accommodate attachment of the kettle bell with the collar end CE of the barbell B. According to one example embodiment, the coupling member is configured for both removably engaging the collar end of the barbell B and for coupling to a portion of the kettle bell. In example forms, the coupling member can provide for removable engagement with the grasping ring of the kettle bell. In some example embodiments, on or more fasteners, clips, latch mechanisms, couplings, etc. provide for removably securing the kettle bell to the collar ends of the barbell B. 
     According to another example embodiment, the present invention relates to a retrofitted kettle bell, which can be used for grasping by one or more hands of a user to perform one or more exercises, or for removably attachment to collar ends of a barbell for performing one or more exercises utilizing the barbell. Thus, in example embodiments, a user can utilize one or more retrofitted kettle bells for performing a plurality of different exercises (with or without a barbell B), for example, rather than only being able to utilize the kettle bell for user-performed exercises where the user grasps the handle with one or more hands. 
     According to another example embodiment, the present invention comprises an exercise device, for example, an exercise ball device, or for example, a weighted, multi-use exercise ball  400  (see  FIGS.  9 - 11   ). For example, according to example embodiments, the device  400  can be used for manual interaction with a user (e.g., like a medicine ball), or for example, the ball (or portions thereof) can be used for attachment to a collar end CE of a barbell. In example embodiments, the device  400  comprises a generally cylindrical opening  410  extending through the entirety of the device  410 , for example, which is preferably sized and shaped for receiving the collar end CE of a barbell B. According to example embodiments, as depicted in  FIG.  10   , the device  400  generally comprises a plurality of panels or shells  420  for removable attachment to a frame component  430 . U.S. Patent Application No. 2014/0336021 is incorporated by reference herein in its entirety and discloses an exercise device having a frame and multiple panels for attachment to the frame. According to one example embodiment, the opening  410  is formed by a plurality of cutouts formed in the shells  420 , for example, such that assembly and attachment of the shells  420  to the frame  430  defines the opening  410 . According to example embodiments, the frame  430  can further be utilized as a kettle bell, for example, wherein one or more weighted components or members can be attached to the frame, and wherein a portion of the frame  430  can be grasped by one or more hands of the user (see handle  440 ). According to example embodiments, the shells  420  can be weighted as desired, for example, being formed from a metal, non-metal or other dense material. According to another example embodiment, the frame  430  (and one or more weights attached to the frame  430 ) can be configured for attachment to the collar end CE of a barbell B. 
     Optionally, rather than removably engaging the kettle bells or exercise device with the collar ends CE of a barbell, a curl bar can be utilized, for example, which comprises similar sized collar ends for sliding engagement with the opening of the kettle bell or exercise device. 
     According to one example embodiment of the present invention, the grasping ring of the kettle bell can comprise two generally spaced-apart rings, which are generally integrally formed with the handle, and which are sized and shaped for receiving the collar ends CE of the barbell B. For example, as depicted in  FIGS.  12 - 14   , the kettle bell  500  comprises a base portion or mass  512  and a grasping ring  520 , and a ring or collar member  530  is provided on each extension portion extending from the grasping handle  522 . In example embodiments, the collar members  530  define receivers or openings  532  passing therethrough, for example, such that the collar end CE of a barbell B is removably engagable with the collar members  530  of the grasping ring  520 , for example, wherein the openings  532  are generally sized to permit insertion of the collar end CE therethrough. In example embodiments, the grasping ring  520  can be grasped for manual exercise (e.g., the grasping handle  522 ) or can removably engage the collar end CE of a barbell B, or for example, other collar ends CE as described herein, for example, a curling bar, shorter barbell or other bar or device comprising one or more collar ends CE. Preferably, the base portion or mass  512  can be shaped as desired. 
     As depicted in  FIG.  13   , the mass  512  comprises a pair of receivers  516  for receiving extension ends  524  of the extensions of the grasping handle  522 . In some example embodiments, the grasping ring  520  and mass  512  are separately formed and permanently connected together. In other example embodiments, the grasping ring  520  and mass  512  can be configured for removable coupling engagement, for example, such that one or more other grasping rings can be interchanged with the mass  512 , for example, to provide additional functionality and/or connectability. According to another example embodiment, the grasping ring and the mass can be integrally formed together as one piece, for example, by a cast, molding, or other available manufacturing process. 
     As depicted in  FIG.  14   , the kettle bell  500  is removably mounted to a collar end CE of a curl bar. Preferably, according to example embodiments of the invention, an opening or pass-through  540  is defined between the grasping handle  522  and the collar end CE. Preferably, the pass-through  540  allows for grasping of the grasping handle  522  when the kettle bell  500  is removably mounted to the collar end CE, for example, such that the user can easily remove or place the kettle bell on the collar end CE as desired. 
     As described above and according to example embodiments, the kettle bell  500  is generally formed from a cast iron material, or can optionally be formed with other dense metals or other materials, sand, etc. According to other example embodiments, the kettle bell  500  can be formed from one or more materials as desired. According to some example embodiments, substantially dense pellets or other small spherical members or other media can be filled within a reservoir defined by at least a portion thereof. In some example embodiments, the dense pellets comprise a high packing factor, for example, to maximize the amount of pellets that can be contained within the reservoir. According to example embodiments, the total weight of the kettle bell  500  is generally between 5-115 lbs. According to some example embodiments, the kettle bell  500  can be configured to be weighted generally similar to known disc-shaped weights, for example, between about 5-45 lbs. Optionally, as described above, the kettle bell  500  can be weighted as desired, for example, which can be more than 45 lbs. 
     According to additional example embodiments, one or more kettle bells can be removably mounted and temporarily secured to the male receivers or collar ends of a barbell or other exercise equipment (free weight and/or exercise machine) as desired. For example, according to some example embodiments, one or more kettle bells comprising a receiver opening can be configured for removable attachment to a male portion (e.g., for receiving one or more weights) of an exercise machine. For example, where the exercise machine comprises a male portion or shaft that is generally used for receiving one or more disc weights, one or more kettle bells comprising the at least one receiver opening or other male attachment member or mechanism can be removably mounted to the male portion of the exercise machine. According to further example embodiments, one or more additional accessories or other members, mechanisms, clamps, clips, rings, clasps, or other features formed with the bell or separate and mountable to the kettle bell can provide for removable mounting thereof to a barbell or other free weight bar or exercise machine. In example embodiments, a separate piece is provided such that the kettle bell can be retrofitted for removable and secure attachment to a barbell or other free weight bar or exercise equipment. 
       FIGS.  15 A-B  show a kettle bell  600  according to another example embodiment of the present invention. As depicted, the kettle bell  600  is generally similar to the kettle bell  500  as described above. According to example embodiments, the kettle bell  600  comprises a base portion or mass  612  and a grasping ring  620 , and a ring or collar member  630  is provided on each extension portion extending from the grasping handle  622 . In example embodiments, the collar members  630  define receivers or openings  632  passing therethrough, for example, such that the collar end CE of a barbell B is removably engageable with the collar members  630  of the grasping ring  620 , for example, wherein the openings  632  are generally sized to permit insertion of the collar end CE therethrough. In example embodiments, the grasping ring  620  can be grasped for manual exercise (e.g., the grasping handle  622 ) or can removably engage the collar end CE of a barbell B, or for example, other collar ends CE as described herein, for example, a curling bar, shorter barbell or other bar, device or exercise equipment comprising one or more collar ends CE. Preferably, the base portion or mass  612  can be shaped as desired. 
     In example embodiments, the mass  612  comprises a pair of receivers  616  for receiving extension ends  624  of the extensions of the grasping handle  622 . In some example embodiments, the grasping ring  620  and mass  612  are separately formed and permanently connected together. In other example embodiments, the grasping ring  620  and mass  612  can be configured for removable coupling engagement, for example, such that one or more other grasping rings can be interchanged with the mass  612 , for example, to provide additional functionality and/or connectability. According to another example embodiment, the grasping ring  620  and the mass  612  can be integrally formed together as one piece, for example, by a cast, molding, or other available manufacturing process. According to one example embodiment, the entirety of the grasping ring  620  is formed from a flexible and/or resiliently deformable material, for example, so as to impart at least some deformation of the handle during use. For example, as depicted in  FIG.  15 B , a user is grasping the grasping handle  622  and applying a downward force, for example, such that the collar members  630  become at least partially deformed and with the openings  632  thereof becoming noncircular or at least partially irregular in shape. According to example embodiments, for example, when the kettle bell  600  is being used for manually lifting (e.g., swinging the kettle bell), the user (while grasping the kettle bell) moves the kettle bell in a pendulum motion from between the knees to anywhere between eye level to fully overhead. Preferably, during the manual lift/swing, the collar members  630  at least partially deform between a neutral state (e.g., zero to minimal force being applied to the kettle bell and/or handle) and a deformed state (e.g., at least some force being applied to the kettle bell and/or handle). As such, the kettle bell  600  is preferably configured so as to impart at least some dynamic movement during its use. According to one example embodiment, at least a portion of the grasping ring  620  is at least partially resiliently deformable relative to the mass  612 . According to one example embodiment as described above, the entirety of the grasping ring  620  is formed from a flexible/deformable material. According to another example embodiment, the grasping handle  622  and the extension ends  624  are substantially rigid while the collar members  630  are at least partially flexible/deformable. According to yet another example embodiment, one or more portions of the grasping ring  620  are flexible/deformable, for example, which can be provided at the grasping handle  622 , the collar members  630 , the extension ends  624 , where the grasping handle  622  connects to the collar members  630 , where the collar members  630  connect to the extension ends  624 , and/or where the extension ends  624  connect to the receivers  616 . 
     According to one example embodiment, the collar members  630  at least partially deform while the user is performing an exercise therewith. For example, while performing a kettle bell swing, the upward pendulum motion of the kettle bell exerts a force on the collar members  630 , for example, which cause the same to at least partially deform, for example, so as to cause at least some displacement between the grasping handle  622  and the mass  612 . In example embodiments, the collar members  630  can be configured so as to impart a minimal, maximum or some amount deformation defined therebetween. In example embodiments, the material thereof and/or the size, shape, etc. of the collar members  630  (or other portions thereof) can be chosen as desired, for example, to provide a desired amount of deformation thereto. According to example embodiments, the grasping ring  620  (or various portions thereof) can be formed from one or more materials including rubber, rubber-like materials, polymers, synthetic materials, natural materials, composites, wood, metals and/or combinations thereof. Preferably, the grasping ring  620  (or any portions thereof) can comprise a desired modulus of elasticity, for example, a low modulus (e.g., substantially flexible), a medium modulus (e.g., at least partially flexible) or a high modulus (e.g., stiff). According to one example embodiment, at least a portion of the grasping ring  620  can comprise one or more portions that are co-molded and/or over-molded, for example, such that two or more materials are used to construct the same. 
     As similarly described above, the kettle bell  600  can be removably mounted to a collar end CE of an exercise device or equipment. Preferably, according to example embodiments of the invention, an opening or pass-through is defined between the grasping handle  622  and the collar end CE. Preferably, the pass-through allows for grasping of the grasping handle  622  when the kettle bell  600  is removably mounted to the collar end CE, for example, such that the user can easily remove or place the kettle bell on the collar end CE as desired. 
     Referring back to  FIG.  15 A , according to some example embodiments a pair of inserts  640  can be provided for removable engagement with the collar members  630  of the grasping ring  620 . For example, when it is desired to prevent deformation of the collar members  630 , inserts or stiffening components  640  can be removably mounted thereto such that the collar members  630  remain rigid and do not deform or flex during use. According to one example embodiment, each stiffening component  640  comprises a central male ring  642  (for insertion within the opening  630 ) and an outer flange portion  644  generally extending outwardly for seating against at least a portion of the collar member  630 . According to other example embodiments, the stiffening components  640  can preferably be shaped, sized and configured as desired, for example, so as to provide for removable engagement with at least a portion of the collar members  630  (or other portions of the grasping ring  620 ) so as to act as a stiffening agent or component to make the grasping ring  620  (or other portions thereof) substantially, if not entirely rigid. According to some example embodiments, the stiffening components  640  can comprise one or more clips, clasps, engagement components or other engagement features, for example, so as to ensure that they remain removably engaged with the collar members  630  during use. According to some example embodiments, the stiffening components  640  can be formed from one or more materials including metals, non-metals, composites, plastics, polymers, rubber, synthetic materials, natural materials, wood and/or combinations thereof. According to some example embodiments, the stiffening components  640  can additionally be weighted as desired, for example, such that the weight of the kettle bell  600  is adjustable. For example, according to some example embodiments, the stiffening components  640  can be provided in a plurality of densities, for example, such that a user can increase the weight of the kettle bell  600  as desired. According to some example embodiments, the stiffening components comprise a high modulus of elasticity, and thus, are substantially stiff. According to other example embodiments, the stiffening components comprise a low to medium modulus of elasticity, and thus, can resiliently deform to some extent. 
       FIG.  16    shows a kettle bell  700  according to another example embodiment of the present invention. In example embodiments, the kettle bell  700  is generally similar to the kettle bell  500 ,  600  as described above. According to a preferred example embodiment, the grasping handle  722  of the grasping ring  720  comprises a rotatable grasping handle component  740  rotatably mounted thereon, for example, which can be configured or adjustable to either permit or prevent rotation thereof relative to the grasping handle  722 . As such, in a preventative mode, the rotatable grasping handle component  740  is fixedly mounted to the grasping handle  722 , and for example, acts as a normal rigid kettle bell handle. However, in a rotating mode, the rotatable grasping handle component  740  can freely rotate about the grasping handle  722 . Accordingly, in the rotating mode, the kettle bell is free to swing about the rotatable grasping handle component  740 , and thus, imparts one additional degree of freedom so as to permit additional movement thereof while a user grasps the component  740  to perform one or more exercises (e.g., lifting/moving the kettle bell  700 ). According to example embodiments, a user can easily manipulate the component  740  between the preventative and rotating modes. 
     According to one example embodiment, the grasping ring  720  comprises an internal skeletal support structure  750  (see dashed lines), for example, which is covered with one or more desired materials so as to impart a desired feel, flexibility, resiliency, stiffness, etc. thereto. For example, according to one example embodiment, the grasping ring  720  comprises a skeletal support structure  750  and an over-molded or co-molded layer surrounding at least a portion of the skeletal support structure  750 . According to example embodiments, the skeletal support structure  750  can be formed from a desired material, for example, metals, natural materials, polymers, plastics, composites, unnatural materials, synthetic materials and/or combinations thereof. According to one example embodiment, a metal comprising a low to medium modulus of elasticity can be used as the skeletal support structure  750 , for example, such that at least some deformation of the handle is permitted (e.g., as similarly described above). According to another example embodiment, one or more resilient and flexible (yet structurally sound) metal cables or other components can be incorporated with the grasping ring  720  as desired. In yet another example embodiment, the skeletal support structure  750  can be substantially rigid such that the grasping ring  720  retains its shape and imparts minimal (if any) deformation during use. 
     According to one example embodiment, the ends of the extension ends  724  comprise an engagement feature  726  for providing engagement with an engagement feature  718  that is formed within the receivers  716  of the mass  712 . Thus, according to example embodiments, the grasping ring  720  is manufactured separately from the mass  712 , and an assembly step is provided whereby the extension ends  724  are fitted with the receivers  716  such that interengagement is provided between the engagement features  726 ,  718 , thereby connecting the grasping ring  720  to the mass  712 . As depicted, the engagement features  726  of the extension ends  724  are shaped to permit one-way engagement (e.g., see angled surfaces), and thus, the overhang portions of the angled surfaces engage with the engagement features  718  of the receivers  716  to prevent disengagement. 
     Referring to the skeletal support structure  750 , according to one embodiment the structure  750  comprises lower extension portions  752 , base portions  753 , intermediate collar portions  754 , and an upper connector portion  756 . In example embodiments, the base portions  753  are configured to be substantially secured with the over-molded or co-molded material, for example, such that the skeletal support structure  750  (and lower extension portions  752  thereof) would be prevented from separating from the over-molded or co-molded material (or from the engagement features  718 ,  726  or receivers  716 ) during use. According to one example embodiment, the skeletal support structure  750  comprises one or more linked components (e.g., a chain of components), for example, which are connected together but still permit at least some relative movement therebetween. As such, if it is the case that the skeletal support structure  750  does permit at least some relative movement therebetween, the co-molded or over-molded material can be chosen so as to provide a desired amount of flexibility and deformation to the entirety (or at least one or more portions) of the grasping ring  720 . According to example embodiments, the co-molded or over-molded material can comprise a desired modulus of elasticity, for example, a low modulus (e.g., substantially flexible/deformable), a medium modulus (e.g., at least partially flexible) or a high modulus (e.g., stiff). 
       FIG.  17    shows a kettle bell  800  according to another example embodiment of the present invention. In example embodiments, the kettle bell  800  is generally similar to the kettle bell  10  as described above. According to example embodiments, the kettle bell  800  comprises a weighted mass or object  812 , with a generally flat bottom  814  for resting atop a support surface SS, and a handle  820  extending from an upper portion of the mass  812  to form a grasping ring  822 . In example embodiments, the weighted mass or object  812  can be shaped as desired, for example, spherical, cylindrical, or for example, can take on any shape or desired form. According to one example embodiment, the weighted mass  812  is shaped to form a bust-like head of an animal, person or other ornamental shape or configuration. 
     In example embodiments, an opening  824  is defined between the ring  822  and the upper portion of the mass  812 . In preferred example embodiments, an opening  830  (comprising a diameter D 2 ) extends entirely through a generally central area of the mass  812 , for example, to provide for accommodating an insert component  840 . In example embodiments, the insert component  840  is removably mountable to at least a portion of the mass (e.g., within the opening  830  according to one example embodiment), and for example, comprises a central collar or receiver  842  (comprising an opening  846  and defining a diameter D 1 ) for receiving the collar end CE of a barbell or other exercise device or equipment. According to example embodiments, the diameter D 1  is about 2 inches, or for example, at least large enough for permitting engagement with the collar end CE of a barbell (or other exercise equipment). In example embodiment, the diameter D 2  can be chosen as desired, for example, being at least partially larger than the diameter D 1 . For example, according to one example embodiment, the diameter D 1  is about 2 inches and the diameter D 2  is between about 2.1 inches to about 6 inches, for example, between about 2.1 inches to about 5 inches, for example, between about 2.1 inches to about 4 inches. Optionally, the diameters D 1 , D 2  can be chosen as desired. 
     In some example embodiments, the insert component further comprises an outer medium  844  that surrounds the receiver  842  and is fitted within the opening  830 . According to one example embodiment, the outer medium  844  comprises a material that is at least partially deformable, flexible and/or resilient. According to one example embodiment, the outer medium  844  comprises foam. According to one example embodiment, the foam is open-cell foam. According to another example embodiment, the foam comprises closed-cell phone. In other example embodiment, the medium comprises rubber, an air-filled bladder, natural materials, synthetic materials, and/or other materials and/or combinations thereof as desired. Preferably, according to example embodiments, the outer medium  844  can be chosen so as to provide for at least some displacement thereto. According to one example embodiment, the outer medium  844  is deformable such that the receiver  842  is at least partially displaced while remaining within the opening  830 . Thus, according to example embodiments, when the collar end CE of a barbell, exercise equipment or component is fitted with the receiver  842 , movement of the collar end CE (and kettle bell  800  connected thereto) can cause deformation of the outer medium  844  and thus permit at least some displacement of the receiver  842  relative to the opening  830 . 
     Accordingly, the insert component preferably provides for at least some dynamic movement of the kettle bell  800  relative to the collar end (or other exercise equipment) during movement of the same, for example, such as movement during an exercise, lift or other activity. As similarly described above, the opening  830  (and receiver  842 ) are generally offset from the center-of-mass CM of the kettle bell  800 , and thus, permits rotation of the kettle bell  800  with respect to the collar end. According to example embodiments, the kettle bell  800  is configured to challenge a user during use, for example, when removably attached to the collar end of an exercise device, for example, such that additional degrees of stability are required (e.g., receiver being offset and deformable insert). 
     According to some example embodiments, the deformable insert  840  can be formed to provide a desired amount of flexibility (deformation), for example, so as to increase or decrease the movement of the receiver during use. According to some example embodiments, for example, when the kettle bell  800  is used for manual lifting, the insert  840  can be removed therefrom, or for example, a weighted insert can be provided, for example, so as to provide adjustability to the weight of the kettle bell  800 . According to another example embodiment, the insert  840  can comprise at least one moveable weight contained therein, for example, such that movement of the kettle bell  800  (lifting/swinging) causes the weight of the insert  840  to move therein, and thus, additional stability is required by the user during an exercise. 
     While the invention has been described with reference to preferred and example embodiments, it will be understood by those skilled in the art that a variety of modifications, additions and deletions are within the scope of the invention, as defined by the following claims.
