Stand in machine with one or both legs between pads depending upon machine's design. Position exercising leg with lever pad behind lower leg and upper pad in front of lower thigh. Bend over and grasp handles for support if available. Stand with body weight shifted on foot of resting leg and raise foot of exercising leg slightly off of floor or platform.
Pull lever up to back of thigh by flexing knee. Return lever until knee is straight. Repeat. Continue with opposite leg.
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. Similar exercise can also be performed on some multi-hip machines and certain leg extension machines. Also see Bent-over Leg Curl.
