ABSTRACT:
An exercising apparatus for developing selected muscles of the body comprises a rigid upright support having a first beam pivoted on a horizontal axis near the top of the support and a second beam similarly pivoted below the first beam. The two beams are connected by a telescopic adjustable link so that they move together at selected distances from one another. Handles and shoulder pads are provided for lifting the first beam and a weight holding rod is located on the outer end of the second beam for receiving a selected number of weights to be lifted. The rate of movement of the bars during lifting of the weights is maintained substantially constant by an isokinetic device connected between the structure and one of the beams. The combination of the two beams and the adjustable link facilitates the use of the apparatus for a wide range of sizes of people and a wide range of different exercises.
