Abstract: A training apparatus for improving a golfer's golf swing is disclosed. The training apparatus can restrict movement of the golfer's hands, as well as the shaft of the golfer's golf club, during the swing. A set of rails supported by a support structure are oriented so as to restrict the golfer's hand movement, and golf club shaft movement. The set of rails include at least two rails for inducing the golfer to move the golfer's hands within the hand space, throughout at least a portion of the swing, and at least two rails for inducing the golfer to move the golfer's golf club shaft within the golf club shaft space. The rails can include various adjustability features, allowing for adjusting the height and angular orientation of the set of rails, as well as the spacing and orientation of individual rails relative to each other.
