Knee Swing

Stand straight with feet shoulder-width apart. Grasp a stable support with your hands. It can be a bench back or a squat rack. As you exhale, swing your leg back. At the same time, do not bend either the working or supporting leg. You can use weights to make the exercise more difficult. As you inhale, lower your leg, returning it to its original position. Complete the required number of repetitions. Repeat the exercise with the other leg. Variations: To make the exercise more difficult, you can use a lower block cable with a strap attached to it. Alternatively, you can use an expander.
