Abstract

An exercise apparatus for leg strengthening has a frame, a knee support for supporting a knee of a user relative to the frame, a leg brace for bracing a lower leg of the user relative to the frame, and a linkage assembly facilitating performance of a hamstring curl exercise motion wherein a chest of the user is lowered and then raised relative to the frame. The linkage assembly has a driver arm pivotably coupled to the frame and supporting the chest of the user, a loaded arm pivotably coupled to the frame above the driver arm and providing or supporting a load, and a connecting arm pivotably coupling the driver arm to the loaded arm so that lowering of the chest during the hamstring curl exercise motion is resisted by the load and so that raising of the chest during the hamstring curl exercise motion is assisted by the load.
