ABSTRACT:
An exercise device, as for example, the wing on a butterfly exercise machine, is arranged to be moved from an at rest position in an exercising direction in a range of travel counter to a load and to be returned to the at rest position by the load. An adjustment mechanism between the exercise device and load selectively adjusts the start of the travel range by movement of the exercise device in a direction opposite from the exercising direction. The adjustment mechanism includes a rack and pawl arranged to be engaged with one another when the exercise device is moved in the exercising direction.
