|Utility:||Basic or Auxiliary|
Stand in machine with lower pads behind lower legs, upper pads in front of thighs, and lever fulcrum between knees. Bend over, placing forearms on pads, and grasp handles.
Raise left foot slightly off of floor or platform. Raise lever up with left leg, bending knee as high as possible. Return lever until knee is straight. Shift body weight to left foot and raise right foot slightly off of floor or platform. Raise lever up with right leg, bending knee as high as possible. Continue alternating movement between legs.
The bent-over posture decreases active insufficiency of three of four heads of hamstring at completion of knee flexion. Dorsal flexion of ankle reduces active insufficiency of Gastrocnemius allowing it to assist in knee flexion.
