Stand up straight with your feet shoulders width apart.
Raise your arms in front of you.
When ready, perform a shallow squat movement as you simultaneously draw your arms backward.
Next, forcefully jump into the air as high as you can, using your arms to generate upward momentum.
Ensure you keep your legs straight when in the air and aim to land on the same spot as you started.
Upon landing, instantaneously perform another jump as quickly and as high as you can.
Continue as instructed by your therapist.
