ABSTRACT:
An athletic swing practice apparatus combines arm swing control and upper body swing control in a single swing training system. A pair of flexible arm encircling straps are each shaped to encircle the upper arm of an athletic during a practice swing. An elastic strap extends from each of the pair of flexible arm encircling straps and each elastic strap has an elongated piece of hook and loop material attached thereto for attaching the straps together to form a single elastic strap adjustably connecting the pair of flexible arm encircling straps together by a predetermined distance. A fastener member, such as an aperture with a grommet, is attached to each of the flexible arm encircling straps and a pair of elastic cords has one cord attached to each flexible arm encircling strap through the fastening member. A pair of stationary members, such as upright poles, are attached to the earth a predetermined distance apart and each pole has openings therethrough for attaching the other end of each elastic cord thereto. Thus, a person can practice an athletic swing with each arm having the arm encircling strap thereon connected across the back of the athletic with an elastic strap to apply a predetermined force between the arms during the swing while simultaneously applying a predetermined force to the movement of the upper body by the elastic resilient cords stretched between the arm straps and the upright poles.
