Abstract: A stretch-assisting device, adapted for mounting in a vertical orientation on a door, wall or analogous vertical substrate, features an upper framework portion and a lower framework portion, coupled together. Each framework portion consists essentially of hollow rigid tubing arranged in a loop shape, with attached metal rings which project horizontally.
