ABSTRACT:
A frictional exercising device includes a shell body which can be attached to a substantially stationary object, for instance a door, a doorjamb or a floor. A core cylinder is rigidly mounted in the shell body. The core cylinder has a wall with an arcuate friction surface having bumps formed thereon. A space is defined between the friction surface and the shell body through which a flat strap extends. The flat strap is partially wound around the core cylinder and hugs the friction surface. When one of the ends of the flat strap is pulled and a resistive force is applied at the other end, a frictional force increases between the friction surface and the flat strap.
