One-Legged Cable Kickback
Clip a leather cuff to a cable pulley that’s low and the cuff should be attached to your ankle. With a distance of about 2 feet, face the weight stack and at the same time holding its steel frame for added support. Your hips and knees should be slightly bent and abs tight, contract your buttocks to gradually “kick” the working leg in a semicircular arc going high as you can go.
When at full extension, your buttocks should be squeezed for peak contraction. Working leg forward, at the same time resist the cable’s pull until you get to the starting point. When you have completed the number of desired repetitions, you can complete the same number but this time use the opposite leg.
