Face the weight stack from a distance of about two feet, grasping the steel frame for support. While keeping your knees and hips bent slightly and your abs tight, contract your glutes to slowly kick the working leg back in a semicircular arc as high as it will comfortably go as you breathe out. Tip: At full extension, squeeze your glutes for a second in order to achieve a peak contraction.Now slowly bring your working leg forward, resisting the pull of the cable until you reach the starting position.
