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. The forces overcome first loads due to weights placed on exercise arms to which the force stations are joined. The force stations are located relative to a support that enables a person on the support to exercise selected pairs of muscles. 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.
