ABSTRACT:
An adjustable apparatus for developing bending strength in the muscles of a user. The apparatus simulates the resistance encountered when attempting to bend metal bars with the arms outstretched forwardly and the hands initially in a horizontal, palms downward position, and thus develops specifically those muscles and skills required for such feats. The apparatus is formed of two U-shaped members hinged at their open ends to form an O-shaped assembly. Each U-shaped member has a handle attached near the middle of the base portions, for grasping by the user's hands. Bend-resistant lengths of fairly rigid, yet resilient, material can be added successively between the U-shaped members to obtain an increased resistance to bending pressures, thus providing a device for progressively developing strength in the sets of muscles involved in bending strength.
