Select desired weight. Stand near left side of cable cross machine, and adjust that pulley to the lowest position. Place ankle strap attachment securely around left ankle. Stand tall with abs engaged, feet and knees together, hands lightly gripping the bars for support (or on hips), and weight balanced on your right foot. Lift your left foot off the ground, foot flexed.
EXHALE: Keeping thighs and knees squeezed together, bend the left knee to curl your heel towards your buttocks.
INHALE: Slowly return to the start position to complete one rep.
Balance on your own as much as possible, only holding onto a pole (or similar) for balance if necessary. Only use a weight that you can lift smoothly, without momentum, and make sure the weight stack does not slam between reps. Do not lean forward or backward as you move your leg.
