Cable Standing Leg Curl
Stand with knees slightly bent and feet no more than shoulder width apart. Place strap around ankle. Stabilize upper body by grasping stationary support on cable machine. Stand in good body alignment (abs tight, chest up, back straight). Keep stationary knee slightly bent and fixed throughout movement. In a controlled motion, flex the knee by drawing foot back and up as far as possible. Contract hamstring muscles fully without compromising form; avoid any hip movement. While maintaining the controlled motion, return to starting position without setting down weight or relaxing the muscles. Do not allow the knee to hyperextend.
