ABSTRACT:
An exercise apparatus is provided for use in performing muscle exercise routines, including exercises such as bench presses, arm curls, and leg curls. The exercise apparatus includes a frame, an actuator mechanism, and a resistance mechanism. During an exercise routine, an exerciser moves a bar such as a handlebar, mounted on the actuator mechanism, reciprocatively, through arc movement. A clutch mechanism is provided so that, selectively, as the bar is moved the resistance mechanism is engaged. The resistance mechanism is of a fluid-shearing friction type with a rotating shearing surface acting upon a stationary shearing surface through viscous fluid. The clutch mechanism permits resistance to bar movement to be selectively provided during a forward stroke, or return stroke, or both, during reciprocative movement of the bar. The resistance mechanism includes means permitting an amount of resistance offered by the mechanism to be selectively adjusted.
