Abstract
An exerciser device has a rotary crank assembly turnable in opposite selected directions and driving an endless first chain entrained on sprockets. The chain drives through a first engaged clutch when the crank assembly is turned in one direction to turn a wheel which drives a variable resistance device such as a variable delivery pump. A second chain entrained on other sprockets which are driven by the first chain when engaged by a second clutch, to drive the wheel when the crank assembly is turned in opposite direction. The wheel always turns in the same direction regardless of the direction in which the crank assembly is turned.
