ABSTRACT:
An exercise device for the exercise of a user's muscles by movement through an exercise stroke. The exercise device includes a weight tower frame and concentric and eccentric weight stacks, each having a selected number of weights stacked in a generally vertical array, the weights being movable between lowered and elevated positions. The exercise device further includes selected levers and mechanical linkages designed to respond to force applied by the exercise of the user's muscles by the lifting of selected weights of the concentric weight stack from the lowered to the elevated position. A pneumatic cylinder and related linkages lift from the lowered to the elevated position a selected number of the weights of the eccentric weight stack without additional exertion of the user and, at a selected point in the exercise stroke, are caused to add automatically the weight of the weights so lifted to that of weights of the concentric weight stack lifted by the user.
