Sit comfortably on the machine seat with your knees bent at approximately 90 degrees and your feet positioned shoulder-width apart on the foot platform.
Adjust the thigh pad so it rests securely across your lower thighs just above your knees.
Ensure your heels are hanging off the edge of the platform so that you can achieve a full range of motion.
Brace your core gently and keep your hands resting on the handles or thigh pad for support.
Press through the balls of your feet to lift your heels as high as possible, squeezing your calves at the top of the movement.
Pause briefly at the top, focusing on a strong contraction.
Slowly lower your heels below the level of the platform until you feel a comfortable stretch in your calves.
Complete repetitions as prescribed by your physiotherapist.
