Abstract
Exercise apparatus for building strength in the lower extremities while reducing the risk of injury to knee joints. A weight-bearing lever is pivotable upon a first post located forward and to the side of a seat for the user. A second pivotable arm which has a cushioned leg bar mounted to it is pivotable about a second pivot point on the first post. A roller bearing extends from the pivotable arm and is received by a bearing race fixed to the underside of the weight-bearing lever. As the user moves the leg bar forward and upward, the roller urges the weight-bearing lever upward. The Rolling Fulcrum.TM. pivot support of the weight-bearing lever moves away from the user reducing the moment arm of the weight on the weight-bearing arm as the user's legs approach full extension at the knee.
