ABSTRACT:
Portable exercise apparatus comprises a base plinth pivotably connected to an upright member which carries an upper control and display panel. In the middle of the plinth is a forceplate on which a user can stand or run in place and which is associated with load sensing apparatus. Lateral hand grips are telescopically received in angle supports to enable the user to perform progressive resistance isotonic and isometric exercises, the expended exercise effort again being sensed by the forceplate by comparison to the user's static bodyweight and communicated to the user by visual or audible signals from the control panel. The equipment can be folded away into a flat box structure and carried by a handle.
