CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present disclosure is directed towards an exercise rope, and more particularly, a jump-rope and resistance band having convertible handles. This application claims the benefit of U.S. Provisional Patent Application No. 62/945,923 filed Dec. 10, 2019, the disclosure of which is hereby incorporated by reference herein in its entirety. 
    
    
     BACKGROUND 
     There is a large variety of exercise equipment, and typically a user may use multiple pieces of equipment to work out. A large number of separate pieces of equipment can be unwieldly or otherwise burdensome. 
     SUMMARY 
     In some embodiments, the present disclosure is directed to a system for using as a jump-rope and a resistance band. The system includes an elastic elongate element such as a rope or band, a two handles. The elastic elongate element includes a first end, a second end opposite the first end, and a first rest length extending between the first end and the second end. The handles include a first handle arranged at the first end that is configured to engage the first end of the elastic elongate element. The second handle is arranged at the second end and is configured to engage the second end of the elastic elongate element. The system is configured to achieve two configurations, at least. In a first configuration, the first handle and the second handle are arranged in-line with the elastic elongate element. In a second configuration, the first handle and the second handle are arranged transverse to the elastic elongate element. For example, in some embodiments, the first configuration corresponds to a jump-rope configuration and the second configuration corresponds to a resistance band configuration. 
     In some embodiments, the system includes a first feature arranged along the elastic elongate element proximal to the first end and configured to affix to the first end to form a first loop in the second configuration. In some such embodiments, the system includes a second feature arranged along the elastic elongate element proximal to the second end and configured to affix to the second end to form a second loop in the second configuration. For example, in some embodiments, the second configuration corresponds to a resistance band configuration having a handle loop at each end. In some embodiments, the first feature includes a first loop, and the second feature comprises a second loop, each arranged as part of, or embedded along, the elastic elongate element. For example, in some embodiments, the first and second ends of the elastic elongate element include hooks, clasps, carabiners, openable/closable loops, or any other suitable fastening mechanism to engage with the respective feature. In some embodiments, the system includes a plurality of features arranged along the elastic elongate element. In some such embodiments, the first end of the elastic elongate element is configured to engage any of the plurality of features, and the second end of the elastic elongate element is configured to engage any of the plurality of features. 
     In some embodiments, in the second arrangement, the elastic elongate element forms a first loop at the first end and forms a second loop at the second end. In some such embodiments, the first handle is arranged at the first loop and the second handle is arranged at the second loop. In some embodiments, the first handle includes a first centroid and the second handle includes a second centroid. In some embodiments, the first handle is arranged transverse to the elastic elongate element at the first end, the second handle is arranged transverse to the elastic elongate element at the second end, and the first centroid and the second centroid are closer to each other in the second configuration than in the first configuration. For example, in the resistance band configuration, the handles may be relatively closer together than in the jump-rope configuration. 
     In some embodiments, the elastic elongate element is configured to achieve a length longer than the first rest length when in tension. For example, the elastic elongate element may have an axial stiffness that is suitable for use as a resistance band. In a further example, the elastic elongate element may have a density, pliability, stiffness, any other suitable property, or any combination thereof, for use as a jump-rope. To illustrate, in some embodiments, the elastic elongate element comprises an elastic rope. To further illustrate, the first rest length corresponds to a jump-rope length. 
     In some embodiments, the first handle includes a hollow section, and an inward end and an outward end. In some such embodiments, a first width of the hollow section proximal to the inward end is less than a second width of the hollow section proximal to the outward end. For example, in some embodiments, the second width is greater than or equal to a width of the elastic elongate element. 
     In some embodiments, the first end and the second end of the elastic elongate element are configured to be affixed to each other to form a third loop, wherein the third loop is larger than the first loop or the second loop. For example, in some embodiments, the system may be configured as one large loop, with the handle either slidably disposed or fixed along the large loop. 
     In some embodiments, the first handle includes a first inward end and a first outward end. In some such embodiments, in the first configuration, the first inward end is affixed to the first end of the elastic elongate element. In some embodiments, the system includes a first section affixed to the elastic elongate element proximal to the first end. In some such embodiments, the first inward end of the first handle is affixed to the first end of the elastic elongate element, and the first outward end of the first handle is affixed to the first section to form a first loop at the first end. In some embodiments, the second handle comprises a second inward end and a second outward end and, in the first configuration, the second inward end of the second handle is affixed to the second end of the elastic elongate element. In some such embodiments, the system includes a second section affixed to the elastic elongate element proximal to the second end. For example, in some embodiments, the second inward end of the second handle is affixed to the second end of the elastic elongate element, and the second outward end of the second handle is affixed to the second section to form a second loop at the second end. To illustrate, one or both ends of the elastic elongate element may be bifurcated into two sections that are configured to affix to the same end of a handle in the jump-rope configuration, and affix to opposites ends of a handle in the resistance band configuration. 
     In some embodiments, the first handle includes a first slot extending partially along a longitudinal axis of the first handle. The first slot includes a width that is greater than or equal to a width of the elastic elongate element. In the second configuration, the elastic elongate element extends from inside the first handle through the first slot such that the first handle forms a T-handle. 
     In some embodiments, the present disclosure is directed to a system for using as a jump-rope and a resistance band. The system includes an elastic elongate element having a first end and a second end, a first handle, and a second handle. The elastic elongate element has a first rest length extending between the first end and the second end. The system also includes a first section extending from the first end, and a second section extending from the first end. The first section and the second section are affixed at the first end to form a “Y” at the first end. The first handle affixed to the first section and the second section. The second handle arranged at the second end. For example, in some embodiments, one or both ends of the rope bifurcates with two sections extending outwards. The two sections may be affixed to the inward end of the first handle in the jump-rope configuration, and affixed to opposite ends of the first handle in the resistance band configuration. 
     In some embodiments, the present disclosure is directed to a method for reconfiguring an exercise rope. The exercise rope includes an elastic elongate element, a first handle, and a second handle. The elastic elongate element includes a first end, a second end opposite the first end, and a first rest length extending between the first end and the second end. The first handle is arranged at the first end and is configured to engage the first end of the elastic elongate element. The second handle is arranged at the second end and is configured to engage the second end of the elastic elongate element. The method includes reconfiguring the first handle from a first configuration wherein the first handle is in-line with the elastic elongate element, to a second configuration wherein the first handle is transverse to the elastic elongate element. The method also includes reconfiguring the second handle from a first configuration wherein the second handle is in-line with the elastic elongate element, to a second configuration wherein the second handle is transverse to the elastic elongate element. In some embodiments, the first end includes two first end sections, and reconfiguring the first handle includes affixing an outward end of the first handle to one of the two first end sections, wherein an inward end of the first handle is affixed to the other first end section. In some embodiments, the exercise rope includes a feature arranged along elastic elongate element proximal to the first end, and reconfiguring the first handle includes engaging the first end of the elastic elongate element to the feature.

     DETAILED DESCRIPTION 
     The present disclosure is directed to a resistance jump rope with convertible handles.  FIG. 1  shows illustrative exercise rope  100  in configurations  110  and  120 , in accordance with some embodiments of the present disclosure. Exercise rope  100  includes handles  101  and  102 , and a pliable, stretchy “rope” or cord section (e.g., element  103 , as illustrated). As illustrated, handles  101  and  102  are arranged at opposite ends of element  103 . As illustrated, exercise rope  100  is a hybrid jump rope/resistance band. Exercise rope  100  may be used as a jump rope or as a resistance band, which may include pulling, pushing and/or stretching exercise rope  100  to increase muscle tone and definition, for example. 
     In configuration  110 , handles  101  and  102  are configured to be arranged in-line with element  103 , as a jump-rope. In configuration  120 , handles  101  and  102  form respective loops  111  and  112  at opposite ends of element  103 , to form a resistance band configuration. In an illustrative example, element  103  may include a first length in configuration  110 , and a shortened length in configuration  120  where some of the length of element  103  forms loops  111  and  112 . In a further illustrative example, the shortened length of configuration  120  may be desired to correspond to the user&#39;s wingspan, arm length, leg length, or a combination thereof. In a further example, in configuration  110 , element  103  may include sufficient length such that the user can perform jump-rope exercises. 
     To illustrate, the first handle includes a first centroid and the second handle includes a second centroid. In the second arrangement, the first handle is arranged transverse to the elastic elongate element at the first end, the second handle is arranged transverse to the elastic elongate element at the second end, and the first centroid and the second centroid are closer to each other than in the first configuration. As used herein, a centroid refers to the generally accepted definition of a geometric center defined as the arithmetic mean position of all points. For example, if a handle had uniform density then the center of mass and the centroid would be coincident. 
       FIG. 2  shows illustrative use cases  210  and  220  of exercise rope  100 , in accordance with some embodiments of the present disclosure. Use case  210  (e.g., corresponding to configuration  110 ) allows exercise rope  100  to be used as a jump-rope. As a jump-rope, handles  101  and  102  are in-line with element  103 , allowing the user to hold handles  101  and  102  while element  103  is swung around (as illustrated). Use case  220  (e.g., corresponding to configuration  120 ) allows exercise rope  100  to be used as a resistance band. As a resistance band, handles  101  and  102  are arranged normal to end sections of element  103 , allowing the user to hold and pull handles  101  and  102  while element  103  is stretched and contracted along its length (as illustrated). To illustrate, in use case  220 , the user holds handles  101  and  102 , which are included in respective loops  111  and  112 , such that handles  101  and  102  arranged normal, or nearly normal, to a portion of element  103  (e.g., the middle portion having the majority of the length element  103 ). 
     In an illustrative example, handles  101  and  102  can be converted from jump rope handles (e.g., configuration  110 , use case  210 ) into resistance band handles (e.g., configuration  120 , use case  220 ). In some embodiments, handles  101  and  102  are converted by attaching the tip of the rope (e.g., element  103 ) to a portion of the rope below the handle (e.g., inward, toward the center of element  103  relative to each handle), making roughly triangle-shaped loops (e.g., loops  111  and  112 ). To illustrate, the conversion changes handles  101  and  102  from an in-line arrangement for jumping rope to a transverse arrangement to have a suitable grip for certain resistance exercises. As used herein, transverse refers to being perpendicular to, or otherwise arranged at an angle between 45°-90° to another object (e.g., perpendicular, or otherwise nearer to perpendicular than parallel). As used herein, in-line refers to being arranged end-to end with and parallel with and, or otherwise arranged at an angle between 0°-45° to another object (e.g., co-linear, or otherwise nearer to parallel than perpendicular). 
     In some embodiments, handles  101  and  102  may be replaceable, detachable, interchangeable, or otherwise modular. In some embodiments, handles  101  and  102  may include grip material, such as rubber or plastic, to improve handling. In some embodiments, handles  101  and  102  may be weighted to provide more resistance to motion. Handles  101  and  102  may be made from plastic, metal, a composite of more than one material, any other suitable material, or any combination thereof. As illustrated, handles  101  and  102  are hollow to accommodate element  103  inside the handle. For example, element  103  may include a knot, a component affixed to the end, or other suitable feature at each end to prevent the end of element  103  from being pulled out of (e.g., disengaged from) the inboard side of each handle. In a further example, the outward end of each handle may allow element  103  to slide outwards relative to the handle to form loops (e.g., loops  111  and  112 ). 
       FIG. 3  shows a flowchart of illustrative process  300  for reconfiguring an exercise rope, in accordance with some embodiments of the present disclosure. It will be understood that process  300  may be performed to reconfigure an exercise rope, and reversed to perform a reconfiguration. Accordingly, process  300  may be performed in any suitable order, performed partially, performed in reverse fully or partially, or a combination thereof. 
     At step  302 , an exercise rope is used in a first configuration, corresponding to a jump-rope, as illustrated by panel  350 . The handles are inline in the first configuration, as illustrated by one of the handles (e.g., handle  351 ) in panel  350 . Rope  353  includes two loops (e.g., features  355 ), as illustrated, for affixing the end of rope  353  to form loops. Although features  355  are illustrated as including two loops, an exercise rope may include one, two, or more than two features, which may but need not include loops, in accordance with the present disclosure. 
     At step  304 , a first handle of the two handles is reconfigured. As illustrated in panel  360 , the end of the rope includes a feature  354  (e.g., a latching element) and is pulled through the hollow handle (e.g., handle  351 ). Feature  354  is then engaged with one of loops  355  (e.g., a second latching element). 
     At step  306 , a second handle of the two handles is reconfigured. The second handle may be reconfigured similarly as the first handle (e.g., via a similar step as  304 ). In some embodiments, step  306  need not be performed. For example, a user may decide to reconfigure only a single end of the exercise rope. To illustrate, the user may reconfigure one end for a resistance rope grip, and leave the handle on the other end in line with the rope (e.g., to tie around a stationary object or otherwise provide an inline grip). 
     At step  308 , the exercise rope is used in a second configuration, corresponding to a resistance band, as illustrated by panel  370 . The handles are transverse in the second configuration, as illustrated by one of the handles (e.g., handle  351 ) in panel  370 . In an illustrative example, when more than one feature is included, the user may select how large or small to make loop  357  by affixing feature  354  to any of features  355 . 
       FIG. 4  shows illustrative handle arrangement  400  for an exercise rope, in accordance with some embodiments of the present disclosure. Handle  401 , as illustrated, includes slot  431 , which is configured to accommodate rope  403  to form a T-handle or an in-line jump-rope handle. In some embodiments, for example, an exercise rope includes a first handle having a first slot extending partially along a longitudinal axis of the first handle. The first slot includes a width that is greater than or equal to a width of the elastic elongate element. In the second configuration, for example, the elastic elongate element extends from inside the first handle through the first slot such that the first handle forms a T-handle. For example, rope  403  may include a width (e.g., a diameter for a round cross-section) that can pass through the inward end of handle  401  as well as slot  431 . In some embodiments, rope  403  may need to be thinned, by applying tension and stretching rope  403  (e.g., decreasing the diameter), to fit within slot  431  (e.g., so rope  403  does not move into slot  431  during jump-rope activities). In some embodiments, when in the T-handle configuration, rope  403  may be stretched to reduce its width and thus be capable of moving out of slot  431  without overcoming friction forces. In some embodiments, although not illustrated, handle  401  may include a lock, latch, or catch at the open end of slot  431  to prevent rope  403  from moving into slot  431  until the lock, latch, or catch is released. 
       FIG. 5  shows illustrative handle arrangement  500  for an exercise rope, in accordance with some embodiments of the present disclosure. Handle  501 , as illustrated, includes recess  502 , which is configured to accommodate end  506  of rope  503  when in an in-line configuration (e.g., a jump-rope handle). End  506 , as illustrated, includes a latching mechanism (e.g., a closable/openable loop, a clasp, a hook, a carabiner) that is configured to engage with loop  505  to form a handle loop such that handle  501  can be used as a resistance band handle. In some embodiments, rope  503  may include a plurality of loops similar to loop  505  such that the user can select the resulting length of resistance band. 
       FIG. 6  shows illustrative exercise rope  600 , in accordance with some embodiments of the present disclosure. Exercise rope  600 , as illustrated, includes handles  601  and  602 , and a pliable, rope  103 . As illustrated, handles  601  and  602  are arranged at opposite ends of rope  603 . Exercise rope  600  may be used as a jump rope or as a resistance band, which may include pulling, pushing and/or stretching exercise rope  600  to increase muscle tone and definition, for example. 
     In configuration  610 , handles  601  and  602  are configured to be arranged in-line with rope  603 , as a jump-rope. In configuration  620 , the ends of rope  603  are engaged together at coupling  605  (e.g., using any suitable fastening components) to form a loop, with handles  601  and  602  arranged at opposite ends of the loop, to form a resistance band configuration. In an illustrative example, rope  603  may include a first length in configuration  610 , and a shortened length in configuration  620  where rope  603  forms a loop (e.g., the handle-to-handle length may be approximately half of the length of the jump rope configuration). In a further illustrative example, the shortened length of configuration  620  may be desired to correspond to the user&#39;s wingspan, arm length, leg length, or a combination thereof. In a further example, in configuration  610 , rope  603  may include sufficient length such that the user can perform jump-rope exercises. 
       FIG. 7  shows illustrative exercise rope  700 , in accordance with some embodiments of the present disclosure. Exercise rope  700 , as illustrated, includes handles  701  and  702 , rope  703 , and elements  721  and  722 . As illustrated, handles  701  and  702  are arranged at opposite ends of rope  703 . Exercise rope  700  may be used as a jump rope or as a resistance band, which may include pulling, pushing and/or stretching exercise rope  700  to increase muscle tone and definition, for example. 
     In configuration  710 , handles  701  and  702  are configured to be arranged in-line with rope  703 , as a jump-rope. In configuration  710 , elements  721  and  722  may be tucked or tied against rope  703 , may be free to move about the respective attachment point, or may be connected to the inward end of the respective handles  701  and  702 . In configuration  720 , handles  701  and  702  form respective loops  711  and  712  at opposite ends of element  703  by attaching elements  721  and  722  to the outward ends of respective handles  701  and  702 , to form a resistance band configuration. In an illustrative example, rope  703  may include a first length in configuration  710 , and a shortened length in configuration  720  where some of the length of rope  703  forms loops  711  and  712 . In a further illustrative example, the shortened length of configuration  720  may be desired to correspond to the user&#39;s wingspan, arm length, leg length, or a combination thereof. In a further example, in configuration  710 , rope  703  may include sufficient length such that the user can perform jump-rope exercises. 
       FIG. 8  shows one end of illustrative exercise rope  800  having a handle arrangement with two fasteners, in configurations  810  and  820 , in accordance with some embodiments of the present disclosure. As illustrated, exercise rope  800  includes rope  803 , first section  804 , second section  805 , junction  831 , end  832 , end  834 , fastener  833 , fastener  835 , and handle  801  having elements  836  and  837  arranged at either end. It will be understood that while only a single end of exercise rope  800  is illustrated in  FIG. 8 , exercise rope  800  may include a re-configurable handle on the opposite end (not illustrated in  FIG. 8 ), which may be but need not be the same as the arrangement illustrated in  FIG. 8 . 
     Rope  803 , as illustrated, terminates at junction  831 , and sections  804  and  805  are also affixed to junction  831  and extend away from rope  803 . In some embodiments, either or both of sections  804  and  805  may be components of, continuous with, or otherwise be part of rope  803 . For example, in some embodiments, rope  803  may bifurcate at junction  831  to form sections  804  and  805 . In a further example, in some embodiments, rope  803  may extend through junction  831  to form section  804 , and section  805  may be a separate strap, cable, or section of rope affixed to junction  831 . 
     Configuration  810  corresponds to handle  801  being used as a jump-rope handle. In some embodiments, sections  804  and  805  are affixed via respective fasteners  833  and  835  to element  836  of handle  801 . As illustrated, element  836  includes a loop to which fasteners  833  and  835  may be engaged. For example, as illustrated, fasteners  833  and  835  include spring-loaded hooks configured to engage either element  836  or element  837 , and also respective loops for affixing to respective ends  832  and  834  of respective sections  804  and  805 . Because both of sections  804  and  805  are affixed to one end of handle  801  in configuration  810  (e.g., at element  836  only), handle  801  may lie in-line or nearly in-line with rope  803  and thus provides a jump-rope handle arrangement. In some embodiments, either or both of elements  836  and  837  are configured to swivel (e.g., via bearings or bushings) about the longitudinal axis of handle  801  to allow rope  803  to re-orient about the longitudinal axis during use (e.g., to prevent binding of fasteners  833  and  835 ). 
     Configuration  820  corresponds to handle  801  being used as a resistance band handle. In some embodiments, sections  804  and  805  are affixed via respective fasteners  833  and  835  to respective elements  836  and  837  of handle  801 . As illustrated in configuration  820 , elements  836  and  837  each include a loop to which respective fasteners  833  and  835  are engaged. For example, as illustrated, fasteners  833  and  835  are configured to engage respective elements  836  and  837  to form loop  821 . Because sections  804  and  805  are affixed to opposite ends of handle  801  in configuration  820 , handle  801  may be arranged transverse or nearly transverse to rope  803  and thus provides a resistance band handle arrangement. 
     In an illustrative example, in order to switch from configuration  810  to configuration  820 , a user may disengage fastener  835  from element  836 , and then engage fastener  835  to element  837 . In a further illustrative example, in order to switch from configuration  820  to configuration  810 , a user may disengage fastener  835  from element  837 , and then engage fastener  835  to element  836 . 
       FIG. 9  shows one end of illustrative exercise rope  900  having a retractable handle arrangement, in configurations  910  and  920 , in accordance with some embodiments of the present disclosure. As illustrated, exercise rope  900  includes rope  903 , fastener  933  (e.g., arranged at an end of rope  903 ), feature  935 , and handle  901 . It will be understood that while only a single end of exercise rope  900  is illustrated in  FIG. 9 , exercise rope  900  may include a retractable handle on the opposite end (not illustrated in  FIG. 9 ), which may be but need not be the same as the arrangement illustrated in  FIG. 9 . 
     Rope  903 , as illustrated, includes an end with fastener  933  affixed. As illustrated, handle  901  includes hollow recess  905 , into which the end of rope  903  is capable of being arranged. As illustrated, handle  901  includes elements  902  and  902 , which act as guides and hard-stops for rope  902  and the end of rope  903  (e.g., with fastener  933 ). 
     Configuration  910  corresponds to handle  901  being used as a jump-rope handle. In some embodiments, in configuration  910 , fastener  933  is arranged in hollow section  905 , with rope  903  passing through holds of elements  902  and  903  arranged in hollow section  905 . To illustrate, elements  902  and  903  may be washer-shaped, and made of any suitable material (e.g., a bushing material to reduce friction against rope  903 ). For example, as illustrated, fasteners  933  includes a spring-loaded openable/closable hook configured to engage feature  935 . Because fastener  933  is affixed to one end of rope  903 , and is retractable inside of handle  901  in configuration  910 , handle  901  may lie in-line or nearly in-line with rope  903  and thus provides a jump-rope handle arrangement. In some embodiments, fastener  933  is configured to swivel (e.g., via bearings or bushings) about the longitudinal axis of rope  903 . In some embodiments, the end of rope  903  is double over and includes a clamp or other affixment for affixing fastener  933  (e.g., the end of rope  903  forms a loop using a clamp, as illustrated, to which fastener  933  is engaged). 
     Configuration  920  corresponds to handle  901  being used as a resistance band handle. As illustrated, feature  935  is affixed to rope  903  (e.g., as illustrated, feature  935  includes a loop affixed along the length of rope  903 ). As illustrated in configuration  920 , fastener  933  may be extended from handle  901  and engaged with feature  935  to form loop  921 . Loop  921  allows handle  901  to lie transverse to most of the length of rope  903 , and thus function as a resistance band handle. In an illustrative example, as illustrated, a plurality of features similar to feature  935  may be affixed as part of rope  903  arranged at different positions along rope  903  to allow a user to adjust the length of the resistance band by selecting the corresponding feature (e.g., engaging features nearer to the center of rope  903  allow for a shorter resistance band). 
     In an illustrative example, in order to switch from configuration  910  to configuration  920 , a user may extend fastener  933  from hollow section  905 , and then engage fastener  933  to feature  935 . In a further illustrative example, in order to switch from configuration  920  to configuration  910 , a user may disengage fastener  933  from feature  935 , and then retract fastener  933  into hollow section  905  of handle  901 .
