|Utility:||Basic or Auxiliary|
Place platform to one side of padded lever. Have additional padded board in hand. Facing machine, stand to one side of padded roller. Place far leg on elevated platform. Position closest leg into apparatus by placing back of lower leg against lever roller. Place extra padded board between knee and edge of seat. Position knee forward securely against padded board and edge of seat. Bend over seat by bending hips and support torso with arms.
Pull lever to back of thigh by flexing knee. Return lever until knee is straight. Repeat. Continue with opposite leg.
A leg extension with padded rollers with access to both sides is required. If needed, raise body slightly by raising heel so lever fulcrum closer to knee articulation. Disregard calf as stabilizer if this is not necessary. Dorsal flexion of ankle reduces active insufficiency of Gastrocnemius allowing it to assist in knee flexion.
