ABSTRACT:
A portable stretching device includes a seat portion on which the athlete sits so that an upright axle frame of the stretching device extends in an upwardly vertical direction from the area between the athlete's thighs. The athlete then grips a handle which is located at the end of a "swing" arm of the stretching device, which extends outwardly from the upright axle frame, away from the athlete, at approximately chest-level. The stretching device also includes thigh supports on the seat portion, which enable an athlete user to stabilize the device while performing stretching exercises. The athlete user then grips the handle, and then allows a retracting force applied to the swing arm to twist his/her torso to either side while the seat portion of the device remains stationary, thus simulating a full shoulder turn required for an optimal swing for golf, hockey, tennis (and other racquet sports) and baseball and softball. The twisting of the user's torso and the corresponding rotation of the handle via the swing arm turns an axle which is located in the upright axle frame which extends downward into the interior of the seat portion. Thus, the swing arm turns in correspondence with an adjustable tension assembly which retracts the swing arm to a point of least resistance which simulates the full shoulder turn for the user. Through deliberate and repeated use of the invention, the athlete is able to significantly increase flexibility, as well as strengthen, the muscles utilized in producing a more open shoulder turn which is beneficial in sports such as golf, hockey, baseball and softball.
