1
Stand upright in a Smith machine or power rack with feet positioned on a platform or box, with balls of feet on the edge and heels hanging off. Grasp the barbell across shoulders or hold the machine handles for balance with arms bent at 90 degrees.
2
Position feet shoulder-width apart with toes pointing forward. Ensure heels are fully extended below the platform in the starting position. Engage core and maintain neutral spine throughout the movement.
3
Lower heels downward in a controlled manner by allowing ankles to dorsiflex, stretching the calf muscles maximally. Keep knees slightly bent and stable, lowering for 2-3 seconds until maximum stretch is achieved in the calves.
4
Push through the balls of feet and contract the calves powerfully to raise heels upward, plantarflexing the ankles. Return to the starting position at top of the range of motion, pause briefly at peak contraction, then repeat.
