Abstract: A golf training device adapted for attachment to a golf club grip for training a golfer to pivot and maintain a solid leading arm is disclosed. The device includes a body contacting arm having a first end adapted for attachment to the golf club grip and a free second end which contacts the body of a golfer when the golfer fails to pivot or maintain a solid leading arm as the golfer strikes a golf ball. The body contacting arm is shaped to lie adjacent, but not touch, the front hip of a golfer when the body contacting arm is properly attached to the golf club grip and the golfer addresses the golf ball. In use, the second end of the body contacting arm moves adjacent, but does not contact, the front hip of the golfer when the golfer pivots and maintains a solid leading arm as the golfer strikes the golf ball. However, the second end of the body contacting arm contacts the golfer if the golfer fails to properly pivot or maintain a solid leading arm as the golfer strikes the golf ball.
