Stand upright with your feet hip-width apart, then step one foot slightly forward so your stance is staggered—roughly one foot-length between front and back.
Distribute your weight evenly between both feet, but slightly more through the rear leg, which will be doing the majority of the work.
Press down through the ball of the rear foot to slowly lift both heels off the ground, rising onto the balls of your feet.
Pause briefly at the top, ensuring control and balance.
Slowly lower both heels back to the ground in a controlled manner.
Complete repetitions as prescribed by your physiotherapist.
