## Background
TECHNICAL FIELD
This invention relates to devices used for athletic training. This invention relates more particularly to a device for strengthening and training the muscles used during hitting movements.
BACKGROUND
Detailed anatomical study and training of athletes engaging in sports involving hitting or swinging movements, such as golf, softball, and baseball, have indicated that the muscles associated with such actions require specialized strengthening and training. Athletic training devices utilizing resilient and extensible tethers, connecting webs, and bands for training specific muscle groups are well known in the athletic training art. By way of example, a device for training the upper body is described in U.S. Pat. No. 5,518,480 to Frappier, herein incorporated by reference. This device is used to provide resistance to the arms, trunk and shoulders to improve performance in sports such as hockey, basketball, volleyball and baseball/softball. A device for training the lower body is described in U.S. Pat. No. 5,167,601 to Frappier, which is incorporated herein by reference. This device provides resistance to the lower extremities during sprinting and related motions.
It is also known to combine two lower body training devices of the type shown in U.S. Pat. No. 5,167,601 to provide resistance to certain muscles used during hitting and swinging movements that require rotation of the hips. These lower body training devices include a thigh band, a calf band, a web connecting the thigh and calf band, and a resilient and extensible tether attached to the web and adapted for attachment to a restraint structure. By connecting the thigh bands of the two devices together around an athlete's waist, and connecting each calf band to the athlete's thighs, resistance is provided to the muscles used during hitting and swinging movements through the tethers, which are attached to a restraint structure.
There remains a need for an improved athletic training device for training the muscles used during hitting and swinging movements. A device capable of strengthening many of the muscles used during these hitting and swinging movements would be desirable. A device of this type that enhances the sequence of related body muscles recruitment would be especially desirable.
SUMMARY
The present invention is an improved hitting and swinging movement training device that can strengthen muscles throughout the body and enhance the sequence of muscle recruitment. One embodiment of the invention includes an arm portion, comprising one or more arm members for engaging one or both of a trainee's arms, a waist portion for engaging a midsection of the trainee's body, and a leg portion, comprising one or more leg members for engaging one or both of the trainee's legs. A resilient and extensible arm tether extends from each arm member to the waist portion, and a resilient and extensible leg tether extends from each leg member for connection to a restraint structure.

FIGS. 4A-4C show a method of training the muscles used during hitting and swinging movements using the hitting harness of FIG. 1. Although the swinging movement shown in FIGS. 4A-4C is a right-handed golf swing, the method shown is applicable to hitting a softball, baseball, or any other hitting or swinging movement. As shown in FIG. 4A, the trainee 29 is wearing the hitting harness 10, holding a golf club 98, and preparing to initiate the backswing. The leg tethers 82 extend from leg connecting webs 64 and are connected to restraint structures 86 located on the floor 96. The trainee 29 is in a neutral position. In this neutral position, the leg tethers 82 are under relatively lower tension. The arm tethers 26 extend from the lower arm bands 24 to the waistband 16. In this neutral position, the arm tethers 26 connecting the arm portion 12 to the waistband 16 are under relatively lower tension. As the trainee 29 moves from the neutral position to the backswing position (shown in FIG. 4B), the tension on the left arm tether 26 and the left leg tether 82 is increased.
FIG. 4B is a front view of the trainee 29 after the completion of the backswing and prior to initiating the down swing. Resistance is provided to the arms 100 through the arm tethers 26 and to the hips 88 and legs 90 through the leg tethers 82. Greater resistance is provided to the left side 55a than the right side 55b of the trainee 29. As the trainee 29 initiates the down swing and moves toward completion of the swing (shown in FIG. 4C), the tension on the left side 55a decreases and the tension on the right side 55b increases.
FIG. 4C is a front view of the trainee 29 at the completion of the swing. As shown, the trainee 29 has completed the rotation of his hips 102 and his swinging movement. The tension on the right side 55b is maximized at this point through the right arm tether 26 and the right leg tether 82. By using the present invention in this manner, the resistance applied to the arms 102, the hips 88, and the legs 90 throughout the swing strengthens and trains the associated muscles in the order they are used in the hitting or swinging motion.
Various modifications and additions can be made to the exemplary embodiments discussed without departing from the scope of the present invention. Accordingly, the scope of the present invention is intended to embrace all such alternatives, modifications, and variations as fall within the scope of the claims, together with all equivalents thereof.
