Abstract: A stretching device comprises a shoulder or body harness with an adjustable central hold arranged around the upper body connected with an adjustable extension strap configured to engage a foot at a distal end. The extension strap is slidably connected to the central strap to move along the length of the central strap. The wearable device and method of using the device provides a comfortable tension and facilitates hands free stretching in the supine position, for improving duration of the stretching and range of motion. The device straps may be quickly disassembled with a strap independently used, or in a combination rearranged for connection by interlocking the central strap with either a shoulder strap or the extension strap, for upper body and shoulder stretching.
