Abstract: An exercise machine utilizes the inherent capabilities of human muscles to exert greater forces during eccentric functions than during concentric functions. The exercise machine comprises a leverage arm pivotally connected to a frame. A force station is at a first distance from the pivotal connection. During a concentric muscle function, a person lifts first weights on the leverage arm. At the end of the concentric muscle function, a spotter applies a small force to the leverage arm at a second distance greater than the first distance from the pivotal connection. The small force produces a magnified load at the force station that the person resists during an eccentric muscle function. The leverage arm may be adjustable relative to the floor. The weight of the leverage arm may be counterbalanced. Various embodiments of the exercise machine utilize the same principles of physics for exercising different muscles.

Abstract: An abdominal exercise machine is provided which includes a seat, which is pivotally linked to a base frame. At least one link includes a handle that can be actuated by a user sitting on the seat. The user presses the handle away from the seat by flexing the trunk muscles of the user. This curls the user's body into a flexed trunk position. As the handle is actuated forward, the linkage arrangement causes the seat to displace upward. This pushes the center of gravity of the user up, thereby doing work and thereby providing resistance to the movement caused by the exercise. The handle may be adjustable in position relative to the link, thereby varying the load used by the user. Foot supports may also be provided either in front of the seat or behind the seat. The foot supports may be mounted to the frame of the seat frame which supports the seat.
