The Leg Extension and Curl Machine provides a full range of motion while performing hamstring curls and leg extensions from the same seated position. Crafted with a rotary leg clamp mechanism that easily allows you to enter the machine, lock your thighs in place, adjust the foot roller starting position, and perform full reps every time, no matter the athlete's size. It is not hard to switch from a leg curl to a leg extension workout by flipping the weight post to the opposite starting position. With this, you can strengthen your muscles simply and effectively!
