Abstract: A golf swing training system with a floor mounted base and a pelvic belt that wraps around the golfer's hips and guides but not unduly restricts the golfer's pivot during the back swing and follow through. The system encourages a pelvic pivot about an axis to the rear of the golfer's right leg in the back swing and down swing, and a pivot about an axis behind the golfer's left leg in the follow through. A multiple pivot mechanism that connects the belt to the base inhibits lateral movement of the hips during the back swing and down swing. The belt is connected to the base by an expandable link pivotally connected at one end to the base and pivotally connected at its other end to the belt, both about generally vertical axes. As the golfer initiates the back swing, the belt pivots about the second axis as the link pivots in the opposite direction about the first axis.
