Performing the: A Step-by-Step Tutorial Exercise Ball on the Wall Calf Raise
Stand with your feet hip-width apart and flat on the ground, and then slowly start to raise your heels off the ground while pushing your back into the ball.
Ensure that you're using your calves to lift your body upwards, not your back or the ball.
Hold the position at the top for a few seconds, where you should be on your tiptoes, then steadily lower your heels back to the floor.
Repeat this process for several reps, making sure to maintain good form throughout.
