Abstract: A resistance system is configured to perform a resistance exercise for an axial base, such as a torso, and a longitudinal member, such as a leg and arm. The resistance exercise helps develop the longitudinal member and axial base by forcing the longitudinal member to pull against different, but constant tension forces, and also forcing the longitudinal member to maintain a proximal distance to the axial base. A short resistance member extends between a foundation mount on the axial base and an intermediate mount on the longitudinal member. A long resistance member extends from the foundation mount, joining with the intermediate mount, and attaching to a distal mount. The short resistance member generates greater tension force than the long resistance member when stretched. The multiple and independent connections made by resistance members create different tension forces for resistance exercises.

Abstract: A golf swing trainer which gives a golfer immediate feedback as to whether the relative timing of the hip movement to the club movement is correct. The trainer comprises a lightweight swing arm which is pivotally connected to the user's belt. For a right handed user, the swing arm on the trainer is initially placed to the right of a right-handed user and is pushed around by the movement of the user's left forearm during a correct golf swing. On the other hand, if the golfer's arms pass in front of the swing arm without swinging it around with the arms, the timing of hip movement was incorrect. In the case of a left handed golfer, the trainer swing arm is initially moved to its far left position and, as before, during the downswing, the user's arms should come in behind and push the trainer swing arm around ahead of the user's arm.

The embodiment restricts lateral sway and promotes hip coiling via a non-stretch strap placed behind a golfer's leg, which is connected at one end to an easily placed, removed, and adjustable hip clip that hooks on a golfer's belt, and at other end to a loose-fitting foot stirrup. The embodiment may be used for training and practice at home, at a golf practice facility, and during a practice round of golf on a golf course.

Abstract: A sport training device wearable by a human user, includes an oblong resilient, flexible member diagonally connecting one side of a shoulder harness to the opposite side of a separate hip harness.

Adjustments are provided adjust the length and tension of the resilient member. A member which deflects uniformly under a compressive load can be used as a measuring device of the relative angle between the hip and shoulder.

Abstract: A golf swing trainer which gives a golfer immediate feedback as to whether the relative timing of the hip movement to the club movement is correct. The trainer comprises a lightweight swing arm which is pivotally connected to the user's belt. For a right handed user, the swing arm on the trainer is initially placed to the right of a right-handed user and is pushed around by the movement of the user's left forearm during a correct golf swing. On the other hand, if the golfer's arms pass in front of the swing arm without swinging it around with the arms, the timing of hip movement was incorrect. In the case of a left handed golfer, the trainer swing arm is initially moved to its far left position and, as before, during the downswing, the user's arms should come in behind and push the trainer swing arm around ahead of the user's arm.

Abstract: This invention is an instruction teaching device to create a proper golf swing. The device helps the user to synchronize their hip rotation with the rotation of their hands. Rotating the hips and hands at the same time is difficult to master, especially for a beginner. With this device, if a user does not rotate his or her hips at the correct time, then the user's hands will encounter the forwardly extending rod that is affixed to the user's waist. Thus, this invention teaches correct timing.
