HIP ABDUCTION

How To Set the pads so they rest against the outside of your knees, and pick a load you can control through the whole range. Sit tall with your back against the pad, feet flat on the footrests, and hold the handles. Exhale and press your knees apart against the pads, driving from the sides of your hips, until you reach the widest point you can hold. Pause for a moment, then inhale and let the pads bring your knees back together slowly; do not let the stack slam. To bias the glutes, lean your torso slightly forward and keep that angle for every rep.
