  • Patent number: 8562451
    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.
