Abstract: A modular system of equipment for physical exercise includes various devices designed for the exercising of different muscles. The system includes a number of separate frame modules, each having an essentially rectangular form and provided with coupling elements enabling the modules to be linked together, or mounted individually on a wall. In addition, the frame modules are provided with mounting elements enabling separate exercising devices without frame structures to be mounted on and supported by the modules.

Abstract: A cam structure for use in athletic exercise and rehabilitation apparatus, in said structure the cam (1) comprising a guiding surface (3) which is eccentric relative to the center of rotation (2) of the cam and on which a force transmission member has been disposed to be carried when the cam is rotated. The cam comprises a second eccentric guiding surface (5), the starting points (4,6) of said guiding surfaces being connected with each other so that the force transmission member can be shifted from the first (3) guiding surface onto the second (5) and back.
