ABSTRACT:
Disclosed herein is a machine for use in exercising the upper arm area by performing what is known as an arm curl. The machine is defined by a seating area, a pivotable arm support table, and a bar fashioned to comfortably engage the hands of the user. This provides a rotation about an axis which is transferred to a cam whose configuration causes proportional resistance throughout the exercise for maximum arm and shoulder development. The cam is operatively connected to weights through a chain drive and the increasing radius of the cam is that which provides the proportional change and resistance.
