ABSTRACT:
A machine for strengthening the leg muscles and for testing the strength of the leg muscles. The machine includes a platform having an actuator end and a weight support end. The platform is pivotally supported by a base. Weights are placed upon the weight support end of the platform. One foot of a standing user is placed upon the actuator end of the platform so as to pivot the platform on the base by the application of pressure by the leg of the user. A pneumatic control system is attached between the base and the platform to provide an adjustable resistance to the pivotal movement of the platform, and for recording the force applied to the platform by the user. An optional stabilizer attachment may be attached to the base for griping by the user to prevent the user from being lifted during applications of extreme force. Alternatively, additional resistance to pivoting of the platform may be provided by use of an elastic cord attachment which is attached to the actuator end of platform and griped by the user.
