Abstract
Abstract A golf practice and exercise apparatus has a shaft with a grip at one end and a variable drag device at the other end. The variable drag device has a main body with opposed edges. Several wings are attached to each of the edges in a manner to be easily removed from the apparatus. The shaft can be held in a golfer's hands and the practice device swung as in striking a golf ball with a golf club, whereupon air resistance of the drag device imparts a force into the golfer's body to improve muscle strength and coordination and to cause the golfer to assume an improved stance which will be remembered with practice.
