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 isolation exercise machine comprises two force stations and a connection mechanism that causes the force stations to rotate in opposite directions in response to applying forces to the force stations.

A leverage arm is attached to the connection mechanism for rotating with one or the other force station. At the end of a concentric muscle function, a spotter applies a small force to the leverage arm. The applied force is converted by the connection mechanism into second loads at the force stations that the person resists during an eccentric muscle function. A counterweight arm and counterweight may be used to cancel out the weight of the leverage arm.
