Lever Alternating Standing Leg Curl

Instructions

Preparation

Stand in machine with lower pads behind lower legs, upper pads in front of thighs, and lever fulcrum between knees. Bend over and grasp handles for support if available.

Execution

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.

Comments

Some apparatuses allow for a bent over posture potentially further decreasing active insufficiency of three of four heads of hamstring at completion of knee flexion. If hips are not significantly bent (ie: body upright), Rectus Femoris becomes antagonist stabilizers. Dorsal flexion of ankle reduces active insufficiency of Gastrocnemius allowing it to assist in knee flexion.
