CROSS REFERENCE TO RELATED APPLICATION[S] 
     This application claims priority to U.S. Provisional Patent Application entitled “GOLF SWING TRAINING AID AND METHOD OF USE THEREOF,” Ser. No. 61/871,451, filed Aug. 29, 2013, now pending, the disclosure of which is hereby incorporated entirely herein by reference. 
    
    
     BACKGROUND 
     1. Technical Field 
     The following relates generally to golf equipment, and in particular to a golf swing training device that aids a golfer in achieving the proper grip of a handle of a golf club. 
     2. State of the Art 
     With so many physical distractions on the golf course, including sand traps, water hazards, deep rough, and wind, just to name a few, and all the other mental details that go into playing the sport of golf effectively, the only thing the golfer truly has control of is the physical connection (i.e., grip) to the handle of the golf club. And, although at first glance the art of gripping the handle may seem simple and even routine, there is much more to it than meets the eye. Indeed, because a golfer&#39;s hands are the link between the golfer and the golf club, the golfer&#39;s grip on the handle is paramount to achieving a high-quality, repetitive golf swing that produces consistent results. The configuration of the hands and fingers is only one aspect of the grip. The grip pressure and the grip pressure consistency through the stroke or swing all affect the proper release for the club and allow the club face to maintain the same orientation through the motion as the original set-up position. 
     Professional golfers and instructors alike will tell you that golf begins with a good grip. Holding the handle of the golf club correctly gives the golfer a feel for the club and is the source of everything that follows in the golf swing. Without achieving the proper grip of the handle, a golfer may never be able master the finer techniques of the golf swing, because the variables in the swing that are compounded by an incorrect grip of the handle will never allow the golfer to do so. 
     Many theories have been introduced and much instruction has been developed to help golfers achieve a proper grip on the handle, including proper hand and finger placement, as well as grip tension and/or pressure, both in a static grip and a dynamic grip. For example, the primary goal of the hands in a static grip is to grip the handle so that the hands and fingers are in the proper placement with respect to one another on the handle and to apply the correct grip pressure on the handle. Thereafter, in a dynamic grip, the golfer swings the club and attempts to make the proper swing according to the shot being executed, while also attempting to square the club face to the golf ball at the point of contact. To achieve this goal, a golfer attempts to grip the handle tightly enough to prevent it from slipping out of the golfer&#39;s hands during the swing and also lightly enough to not cause the golfer to execute a poor golf shot. Indeed, too tight of a grip on the handle may cause the golfer to execute a bad swing, which more often than not results in a poor shot. Moreover, too tight of a grip on the handle may diminish the potential power generated by the golfer. It is therefore the goal to correctly hold the handle properly with the hands and fingers, as well as keep a constant, light grip pressure to the handle which does not change through the swing or putting motion. 
     Yet, even when a golfer understands these principles, putting them into action on the course or on the driving range is a tall order. How much grip strength and grip pressure is appropriate for each individual golfer and each individual type of golf shot is as varied as the individual golfer himself/herself. 
     Accordingly, there is a need in the golf industry for a product and method of use thereof that can assist the individual golfer in learning and repeating the proper grip of the handle of the golf club for any number of golf shots.

     DETAILED DESCRIPTION OF EMBODIMENTS 
     A detailed description of the hereinafter described embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures listed above. Although certain embodiments are shown and described in detail, it should be understood that various changes and modifications may be made without departing from the scope of the appended claims. The scope of the present disclosure will in no way be limited to the number of constituting components, the materials thereof, the shapes thereof, the relative arrangement thereof, etc., and are disclosed simply as an example of embodiments of the present disclosure. 
     As a preface to the detailed description, it should be noted that, as used in this specification and the appended claims, the singular forms “a”, “an” and “the” include plural referents, unless the context clearly dictates otherwise. 
     Referring to the drawings,  FIG. 1  depicts an embodiment of a golf swing training device  10 . Embodiments of the training device  10  may comprise various structural components that complement one another to provide the unique functionality and performance of the training device  10 , the structure and function of which will be described in greater detail herein. For example, embodiments of the training device  10  may comprise a vibration element  30 , a power source  40 , and a control switch  41  configured in the handle of a golf club  8 . The handle of the golf club may comprise the grip of the golf club and the underlying shaft region. 
     Embodiments of the training device  10  may comprise a vibration element  30 . The vibration element  30  may be configured to be in functional communication with the power source  40  via the control switch  41  (ON/OFF switch), such that upon operation of the control switch  41 , the power source  40  can provide power to the vibration element  30  to cause the vibration element  30  to function according to its intended purpose. In other words, upon activation of the vibration element  30  from its inactive state to its active state by the switch  41 , the vibration element  30  may provide vibrational movement, motion, agitation, or other similar repetitive movement to the handle of the golf club  8 . 
     Embodiments of the training device  10  may include the vibration element  30  being configured within a hollow  5  of the shaft  4  of the golf club  8 , as depicted in  FIG. 1 , so as to be out of sight of the golfer and hidden from view. In addition, with the vibration element  30  positioned within the shaft  4 , the vibration element  30  does not interfere with the normal operation of the golf club or putter. With the vibration element  30  positioned within the hollow  5  of the shaft  4 , the vibration element  30  may be in functional communication with the shaft  4  of the golf club  8 , so that under the condition that the vibration element  30  is in an active state, the vibrational movement generated by the vibration element  30  may travel from the vibration element  30  to the shaft  4  and/or the grip  2  and onto the hand(s) of the golfer to indicate to the golfer that the vibration element  30  has been triggered and/or is active. Thus, the golfer can sense or feel the vibration of the vibration element  30  when active. When in the inactive state, the vibration element  30  does not vibrate so that the golfer does not feel the vibration sensation. 
     Embodiments of the training device  10  may be utilized by a golfer to benefit the golfer&#39;s grip on the handle of the club  8 . In most cases, the handle of the club  8  will comprise the grip  2  of the club, the grip  2  being comprised of rubber-type material that is placed on the club  8  around the exterior of the shaft  4  at the distal end of the club  8  away from the club head. The grip  2  may allow the golfer to achieve a better grip on the handle of the golf club  8  to manipulate the golf club  8  during a golf swing or during a golf putting stroke. 
     Activating the vibration element  30  within the golf club  8  can be used to train a golfer to apply the correct grip pressure to the handle or grip  2  of a golf club  8  (i.e., driver, long iron, short iron, or putter). For example, the vibration element  30  that is positioned in the club  8  proximate the grip  2  may serve to accentuate the senses in the golfer&#39;s hands that are positioned on the grip  2 . The vibration element  30  may also serve to accentuate the sensory input in the golfer&#39;s brain received from the golfer&#39;s hands, which helps focus the golfer&#39;s mind. For example, before swinging the golf club  8  or before using the putter, a golfer may manually activate the vibration element  30  by operation of the switch  41 . In this way, the vibration element  30  can provide vibrational input to the handle or grip  2  that can be sensed by the golfer&#39;s hands and processed by the golfer&#39;s mind both before and during the golf swing or putting stroke. 
     Such vibrational effects from the vibration element  30  may serve, among other things, to relax the golfer&#39;s hands, to massage the golfer&#39;s hands, or to continuously remind the golfer&#39;s hands and brain by sensory stimulation of the hands to maintain the correct grip pressure during the swing or putt. For example, such vibrational effects, or massaging effects, may allow the golfer to relax the golfer&#39;s muscles and hands on the handle or grip  2  of the golf club  8  to allow the golfer to apply the correct amount of grip pressure to the handle or grip  2  prior to the swing. Such vibrational effects may also serve to remind the golfer to maintain a constant and consistent grip pressure on the handle or grip  2  during the golf swing or putting stroke. Indeed, such vibrational effects from the vibration element  30  may allow the golfer&#39;s muscles to relax and not grip the handle or grip  2  as tightly as might otherwise be the case. Further to the above, because of the sensory stimulus that the vibrational effects and massaging effects from the vibration element  30  provide to the golfer&#39;s hands, the golfer can more actively feel the physical and functional interaction between the grip  2  and the golfer&#39;s hands than might otherwise be possible without the vibrational effects. Again, this sensory stimulus can help to remind the golfer to apply the correct grip pressure on the handle prior to the swing or putting stroke. This sensory stimulus can also help to remind the golfer to apply consistent and continuous grip pressure on the handle during the swing. In other words, because the golfer can sense the vibrational and massaging effects in his/her hands throughout both the static and dynamic grips of the grip  2 , the golfer&#39;s mind and hands are able to more acutely focus on the application of proper pre-swing grip pressure, as well as on sustaining constant and consistent pressure on the handle or grip  2  during the swing or stroke, despite other distractions around the golfer or on the golf course. Such acute focus benefits the golfer in the execution of any golf shot, but may be more beneficial to the golfer during the putting stroke. 
     Embodiments of the training device  10  may include the vibration element  30  being positioned within the interior of the shaft  4  in a friction fit configuration. Embodiments of the training device  10  may include the vibration element  30  being configured within a module  34  that is configured to be inserted within the interior of the shaft  4  in a friction fit configuration. Embodiments of the training device  10  may include the module  34  being configured to be inserted within the interior of the shaft  4  and held in place by a positioning mechanism  38 . The module  34  may include the vibration element  30 , the power source  40 , and the control  42 . The module  34  may further comprise a housing, in which the vibration element  30 , the power source  40 , and the control  42  may be placed. Advantages of the module  34  being positioned within hollow  5  of the shaft  4  proximate the grip  2  of the club  8  may be that the weight of the vibration element  30 , the power source  40 , and/or the module  34  itself, or the combined weights thereof, may be negligible to the golfer during the golfer&#39;s swing, being that these components are positioned underneath (i.e., within the shaft  4  under the hands) or at least near the golfer&#39;s hands. In this way, the golfer&#39;s swing is not affected, or at least is very minimally affected, even to a negligible degree, due to the weight of the vibration element  30 , the power source  40 , and/or the module  34 , or the combined weights thereof. 
     The vibration element  30  may be any vibration element, now known or later developed, that provides vibration, shaking, shuddering, pulsating, or other similar movement to the degree that it can be felt by the golfer upon activation of the vibration element  30 . For example, the vibration element  30  may be a vibration motor #312-105 manufactured by Precision Microdrives. The vibration element  30  may further comprise an interior motor and a counterweight  32  coupled thereto. The counterweight  32  may be coupled to the drive shaft of the motor, such that as the motor rotates, it drives the counterweight  32 . The counterweight  32  may be configured on the drive shaft to have its weight offset from axial center of the drive shaft, such that when the counterweight  32  rotates, the counterweight produces the vibration, shaking, shuddering, pulsating, or other similar movement about the axial center. However, those of ordinary skill in the art will understand that other brands and similar devices may be incorporated to achieve a vibration, shaking, shuddering, pulsating, or other similar movement in like degree. 
     Embodiments of the training device  10  may include the positioning mechanism  38  being a flexible stopper that is configured to have a diameter or outer circumference size that is slightly less than the diameter of the shaft  4  of the club  8 . In this way, the positioning mechanism  38  may be initially inserted within the distal regions of the shaft  4  near the top of the golf club handle. And, because the shaft  4  generally tapers as the shaft  4  runs from the handle down to the club head, the positioning mechanism  38  should come to rest against the interior of the shaft  4 . Yet, the positioning mechanism  38  may be configured to incorporate an adjustment member  39  that may functionally engage a through bore  37  in the positioning mechanism  38  that causes the positioning mechanism  38  to expand in circumferential size as the adjustment member  39  is advanced into the through bore  37 . By so doing, the positioning mechanism  38  may engage the interior surfaces of the hollow shaft  4  and thereby securely couple to the interior of the shaft  4  at the distal end of the shaft  4  near the grip  2 . Moreover, the adjustment member  39  may be configured to also engage the module  34  in an upper region of the module  34 . Thus, with the positioning mechanism  38  secured to the interior of the shaft  4  and the adjustment member  39  secured to the module  34 , the vibration element  30  may be secured within the interior of the shaft  4  via the module  34 , and thus prevented from axially advancing down the shaft  4 . 
     Embodiments of the training device  10  may include the positioning mechanism  38  being configured to be repeatedly and releasably coupled to the module  34 , such that the positioning mechanism  38  and the module  34  may be detached from one another or reattached to each other as often as determined by the golfer/user. Embodiments of the training device  10  may include the positioning mechanism  38  being fixedly coupled to the module  34 , such that the adjustment member  39  has no need to engage the module  34  to retain the module  34  in its proper position within the shaft  4 . Instead, an upper surface of the module  34  may be fixedly coupled to the positioning mechanism  38 , such that under the condition the positioning mechanism  38  is secured to the interior of the shaft  4 , so too is the module  34  thereby. 
     Embodiments of the training device  10  may include the module  34  having one or more openings, such as a flap or door, wherein the components that are configured therein may be removed, replaced, or repaired, as needed. Embodiments of the module  34  may include the module  34  being hinged on a side thereof so that the module  34  may be laid open for access to the components housed therein. 
     Embodiments of the training device  10  may include a weight reception portion (not depicted) that may be configured to receive weighted portions (not depicted) that may be coupled to the module  34  or to the vibration element  30  to provide additional weight to the club  8  to customize the weight, feel, and customized configuration of the club  8  to the golfer&#39;s individual liking and/or preference. 
     Embodiments of the training device  10  may include one or more vibration elements  30  being configured on the club  8 . Embodiments of the training device  10  may include one or more modules  34  being configured on the club  8 . For example, one vibration element  30  or module  34  may be configured on an interior region of the shaft  4 , and another vibration element  30  or module  34  may be configured on an exterior region of the shaft, such as, for example, but not limited thereto, on the exterior of the grip  2 , on the exterior of the shaft  4 , or near the club head. One or more vibration elements  30  or modules  34  may be functionally coupled to the club  8 , as described herein, at the same or various locations on the club  8  to produce a customized weight distribution and customized vibrational sensation that an individual golfer may prefer. 
     Embodiments of the training device  10  may comprise a power source  40 . The power source  40  may be a battery or other stored-energy source. The power source  40  may be a stackable battery configuration, a single battery configuration, a rechargeable battery configuration, and/or a disposable battery configuration. The power source  40  may be configured to be in functional communication with the vibration element  30  and the control  41 , as herein described, to provide power to these various components, as needed. 
     Embodiments of the training device  10  comprise the module  34 , including, but not limited thereto, the vibration element  30 , the power source  40  and the switch  41  being manufactured with the club  8 . Alternatively, embodiments of the training device  10  comprise the module  34 , including, but not limited to, the vibration element  30 , the power source  40  and the switch  41  being configured to be introduced onto a pre-existing club after manufacture, such that the training device  10  may be an after-market product. 
     With a club  8  equipped with the remaining components of the device  10 , the golfer may utilize the equipped club  8  to train the golfer&#39;s hands to effectuate a better swing or putting stroke. A golf club comprising an embodiment of the device  10  may be provided, as described herein. The golfer may then activate the device  10  with the control switch  41 , such that the club handle begins to vibrate from the vibration motion resulting from the vibration element  30  being placed in its active state by the switch  41 . With the handle of the club vibrating, the golfer may grip the handle of the club (i.e., the grip region of the club). With the hands in the proper position on the grip of the club and with the vibration element  30  sending vibrational effects to the golfer&#39;s hands, as described herein, the golfer can swing the club to execute a golf shot. And, with the vibration element  30  providing vibration to the handle, the golfer is able to apply the proper amount of grip pressure both before and during the swing because of the relaxing effects emanating from the vibrational motion, as discussed herein. 
     With reference now to  FIG. 2 , embodiments of the training device  10  may further comprise the vibration element  30  or module  34  being configured on the back surface of a golf glove  14  to provide vibrational effects directly to the golfer&#39;s hands. In this way, a golfer may wear the golf glove  14  having the module  34  configured thereon and receive the same, or similar, vibrational stimulus as that described above with regard to the golf club  8  equipped with the device  10 . Indeed, embodiments of the training device  10  utilizing the glove  14  may be similar in function to the training device  10  combined into the shaft  4  of the golf club  8 . In other words, the function of the training device  10  as described above with respect to the golf club  8  may also be adapted to function in the same or similar to the glove  14 . 
     Embodiments of the training device  10  may include the vibration element  30 , power source  40 , the control  41 , and/or the module  34  being releasably coupled to the glove  14  by means such as hook and loop fasteners, pockets, sleeves, pouches, straps, belts, hooks, elastic band, buttons or other similar means that might hold these components in place during operation by the golfer. As exemplarily depicted in  FIG. 2 , the module  34  may be positioned within, or under, a cover  15  configured on the back of the glove  14 . Yet, embodiments of the training device  10  may include the vibration element  30 , power source  40 , the control  41 , and/or the module  34  being fixedly coupled to the glove  14  by means such as stitching, adhesive, or other permanent fastening means. What&#39;s important is that the vibration element  30  and/or module  34  can provide vibration effects in the active state to the golfer&#39;s hands both prior to and during the golf swing or putting stroke. Embodiments of the training device  10  further include the module  34  being positioned on the glove  14  at any point on the glove  14  that is out of the way of the normal operation of the glove  14  during a golf swing or putting stroke. 
     Furthermore, embodiments of the training device  10  may include a combination of the vibration element  30  and/or module  34  being placed on the glove  14 , as described, as well as being configured in the handle of the golf club  8 , as described, to provide a combined vibrational effect to the hands of the golfer. 
     With reference now to  FIG. 3 , additional embodiments ancillary to the embodiments described above may include the training device  10  comprising a sensor  20  and a control unit  50 . The sensor  20  may be any sensor, now known or later developed, that is capable of sensing and measuring pressure that is applied to the sensor  20  by exterior forces, such as a golfer gripping the handle or grip  2  of the golf club  8 . 
     For example, embodiments of the training device  10  may comprise a tactile sensor  20  that can be configured on the exterior of the grip  2 , such that the tactile sensor  20  may come into direct contact with the hands of the golfer. The tactile sensor  20  may be coupled to the grip  2  by adhesive, stitching, tape, glue, or other adhesive means. Moreover, the tactile sensor  20  may be formed integrally with the grip  2 , such that the tactile sensor  20  is virtually indistinguishable from the grip  2 . Further, the tactile sensor  20  may be configured to be wrapped around the grip  2  and secured thereto. The tactile sensor  20  may be configured to be removable from the grip  2 . In certain embodiments, the tactile sensor  20  may be configured to be repeatedly and releasably coupled to the grip  2 . The tactile sensor  20  may be configured to be adjustable on the grip  2  in various locations on the grip  2 . Indeed, the configuration of the tactile sensor  20  on the grip  2  may be customizable, for example, but not limited thereto, to the needs and style of the individual golfer, to the particular brand of golf club, or to the type of golf shot being executed. 
     Embodiments of the training device  10  may include the tactile sensor  20  being configured between the grip  2  and the shaft  4  of the golf club  8  (not depicted). The tactile sensor  20  may be coupled to the exterior of the shaft  4  but interior to the grip  2 , such that the tactile sensor  20  resides between the shaft  4  and the grip  2 . The tactile sensor  20  may be coupled to the shaft  4  by adhesive, tape, glue, or other adhesive means. Moreover, the tactile sensor  20  may be configured to be wrapped around the shaft  4  and secured thereto. The tactile sensor  20  may be configured to be removable from the shaft  4  once the grip  2  has been removed from the shaft  4  that covers the tactile sensor  20 . In certain embodiments, the tactile sensor  20  may be configured to be repeatedly and releasably coupled to the shaft  4  under the grip  2 . The tactile sensor  20  may be configured to be adjustable on the shaft  4  in various locations on the shaft  4  under the grip  2 . Indeed, the configuration of the tactile sensor  20  on the shaft  4  under the grip  2  may be customizable to the needs and style of the individual golfer. 
     Embodiments of the training device  10  may include a plurality of tactile sensors  20  positioned in any number of positions on the grip  2 , on the exterior of the grip  2 , or between the grip  2  and the shaft  4 . In this way, multiple force measurements at multiple locations may be measured by the plurality of tactile sensors  20  to provide more detailed feedback of the golfer&#39;s grip on the grip  2 . For example, a plurality of tactile sensors  20  may be positioned on the grip  2  where it might be optimal to place each of the golfer&#39;s palms and/or each of the golfer&#39;s individual fingers. In this way, pressure from various locations on the golfer&#39;s hands may be measured with respect to the handle or grip  2  of the golf club  8 . 
     Embodiments of the training device  10  may include the tactile sensor  20  incorporating a resistive-based sensor that is configured to measure the resistance of a conductive elastomer or foam between two points. Thus, as pressure is applied to the elastomer, the resistive capacity of the elastomer changes, thus producing a measurable variable that corresponds to the amount of pressure applied. In the resistive-based sensor, ultra-thin and flexible printed circuits may be utilized which are designed to bend under applied force and which can be easily integrated into force measurement applications. For example, in a piezoresistive device, resistance is inversely proportional to applied force. 
     Embodiments of the training device  10  may include the tactile sensor  20  incorporating a conductive-based sensor that is configured to measure the capacitance between two parallel plates. For example, as pressure is applied to one of the two plates, the distance between the plates theoretically decreases, thus changing the capacitance and providing a measurable variable that can correspond to the amount of pressure applied. Generally, the two plates are separated by a dielectric medium that gives the capacitance-based sensor its force-to-capacitance characteristics. 
     Embodiments of the training device  10  may include the tactile sensor  20  incorporating a pressure indicating film that releases an indicator in a quantity corresponding to the degree of measured pressure from the golfer&#39;s grip on the grip  2 . In this way, a degree of pressure map may be produced to indicate where the most pressure or force is exerted on the grip  2  by the golfer. In embodiments where the tactile sensor  20  is the pressure indicating film, the film may be replaced for each sampling of the golfer&#39;s grip. 
     Embodiments of the training device  10  may comprise a control unit  50 .

     The communication means may further comprise components that allow the training device  10  to connect to and transmit data and signals between another wireless device that is capable of transmitting data over a wireless network, such as by utilizing Bluetooth® technology, or other short-distance, data-exchange technology. The components may include, but are not limited to, short-range transceivers that send and receive low-power radio waves within the ISM radio-frequency band to facilitate transmission of data between the communication means and the other wireless devices, such as a golfer&#39;s smartphone, tablet, or wireless-enabled device. Operating the control may activate the communication means to establish the communicative connection between the training device  10  and another wireless enabled device, such that the training device  10  can communicate with the wireless enabled device, as determined by the user of the training device  10 . 
     The communication means may further comprise components, such as an accelerometer and/or gyroscope, that allow the training device  10  to be calibrated and set such that the training device  10  may activate upon the golfer taking a swing of the golf club  8  to strike the golf ball. Once activated, the pressure applied by the golfer to the handle or grip  2  can be measured by the sensors  20  and the measurements from the sensor  20 , and/or sensors  20 , can be transmitted and stored in the control unit  50  and/or transmitted to an external computer via one of a wired connection, wireless connection, or other short-distance, data-exchange technology. In this way, the training device  10  may be activated only when needed, thus conserving the power source  40 , and real-time feedback of the golfer&#39;s swing can be gathered and stored within the training device  10  or transmitted to an external storage device, such as a computer hard drive. 
     Embodiments of the training device  10  comprise the control unit  50 , including the communication means and the processing center, in any of the configurations described above, forming part of the module  34  to be inserted within the shaft  4  of the club  8 . 
     Embodiments of the training device  10  may be utilized by a golfer to measure the pressure or force exerted on the handle or grip  2  by the golfer&#39;s hands at any point before, during, or after the golfer&#39;s swing, or during the entire act of swinging, as determined by the golfer and the configuration of the training device  10 . Embodiments of the training device  10  may include the training device  10  being configured to measure and record the pressure and/or force exerted on the grip  2  by the golfer&#39;s hands by one or more sensors  20 . In this way, the golfer may gather a better understanding of the grip pressure being applied by the golfer to the grip  2  of the golf club  8  during the golfer&#39;s swing. The golfer may use this information to alter, amend, correct, or otherwise change the positioning of his/her hands to advantageously benefit the golfer&#39;s swing and the corresponding results therefrom. 
     Embodiments of the training device  10  may include the training device  10  being configured to store a predetermined pressure or force value and thereafter use one or more sensors  20  to measure the force exerted by the golfer during the golfer&#39;s swing to determine if the measured force from one or more of the sensors  20  exceeds the predetermined pressure or force value and to activate the vibration element  30  should one or more of the measured forces exceed the predetermined value. In this way, when the vibration element  30  activates the golfer can determine at what point, or if at all, during the golfer&#39;s swing the golfer&#39;s grip on the grip  2 , at any or all of the one or more sensors  20 , exceeds the recommended pressure or force that should be exerted on the grip  2  during a golf swing of the type being executed. Embodiments of the training device  10  include the predetermined force being adjustable by the golfer for various types of golf shots, including drives, chips, putts, draws, fades, etc. Thus, by using training device  10  in this way and by not triggering the activation of the vibration element  30 , the golfer can be trained not to exceed a recommended, preprogrammed, and/or customizable grip strength on many different types of golf shots. 
     With reference now to  FIG. 4 , embodiments of the training device  10  may further comprise the sensor  20  being configured on a point on the palm surface of a golf glove  14  to measure the pressure or force exerted on the sensor by the golfer placing his/her hand on the club  8  and executing golf swing. Moreover, embodiments of the training device may further comprise one or more sensors  20  being configured on various points on the inside of the palm and hand of the golf glove  14 , as depicted. Additional variations of the locations of the sensors  20  may be utilized to measure pressure and force between the golfer&#39;s hand and the grip  2 , given that the golfer&#39;s hand is inside the glove  14  configured with the sensors thereon. Embodiments of the training device  10  may include the sensors  20  being releasably coupled to the glove  14  by means such as hook and loop fasteners, pockets, sleeves, pouches, or other receptacle-like embodiments that might hold the sensor  20  in place during operation. Embodiments of the training device  10  may include the sensors  20  being fixedly coupled to the glove  14  by means such as stitching, adhesive, or other permanent fastening means. 
     Embodiments of the training device  10  may further comprise the various other components of the training device  10  being configured on the back side (not depicted) of the glove  14 , such that the vibration element  30 , power source  40 , the control unit  50  are configured on the glove  14  but out of the way of the functional aspects of the glove  14 , such as its interaction with the grip  2 . These various components may be gathered together in the module  34 , such that the module  34  need only be coupled to the back side of the glove, or to another portion of the golfer&#39;s body that does not interfere with the golfer&#39;s swing or with the interaction between the glove  14  and the grip  2 . Embodiments of the training device  10  may include the vibration element  30 , power source  40 , the control unit  50 , and/or the module  34  being releasably coupled to the glove  14  or to the golfer&#39;s clothing or body by means such as hook and loop fasteners, pockets, sleeves, pouches, straps, belts, hooks, elastic band, or other similar means that might hold these components in place during operation. Embodiments of the training device  10  may include the vibration element  30 , power source  40 , the control unit  50 , and/or the module  34  being fixedly coupled to the glove  14  by means such as stitching, adhesive, or other permanent fastening means. 
     Embodiments of the training device  10  utilizing the glove  14  may be similar in function to the training device  10  combined into the shaft  4  of the golf club  8 . In other words, the function of the training device  10  as described above may also be adapted to function in the same or similar way but with the sensors  20  deployed on the palm-side of the glove  14  instead of in relation to the club  8  itself. Furthermore, embodiments of the training device  10  may include a combination of the sensors  20  being placed on the glove  14  as well as proximate the grip  2  to take a combined or collective reading from the glove  14  and from the grip  2  of the pressure and force exerted by a golfer on the grip  2  of the club  8  during a golf swing.
