Knee braces generally have been rigid in both the knee bending direction and in the knee straightening direction unless a manually operated release is incorporated in them to allow the knee to bend. Desirably a braced knee joint should effectively duplicate the compound, complex, actions of a normal knee. The key to knee braces is the knee joint housing. The housing herein carries a number of cam action pawls, with teeth adapted to engage the internal teeth of a ratchet ring mounted in the housing. Cam action return springs and the shape of the cam action pawl teeth allow rotation of the ratchet ring in a leg straightening direction while still supporting a load. The leg can then be extended during walking while at the same time being prevented by the cam action pawls from buckling in the knee bending direction.

A unique abdominal bench with a pivoting torso section has a number of pivots, rods, and levers that allow the fixed seat section of the abdominal bench to remain a constant distance from the pivoting torso section during an abdominal exercise. The leg section of the abdominal bench pivots towards the abdomen, as does the torso section when the torso is raised. The leg section is pivotably connected to the torso section through a number of rods, pivots and levers such that the gap between the seat and torso section remains the same. A push rod is connected to the pivoting leg brace and is in turn connected to a torso bracket through several guide rods and a dog-leg lever. The push rod, guide rods and the dog-leg lever allow the torso section to remain a constant distance from the fixed seat section. Allowing the torso and seat section to remain a constant distance eliminates the pressure on the lower body of the exerciser and will not cause any movement of the lower body of the exerciser with respect to the torso section.
