Stand under a doorframe on a slightly elevated surface with your arms extended over your head.
2. Slowly flex your ankle to lower your heels (This is the bottom of the rep).
3. Once your heel touched the ground (Or you felt you can’t flex your ankle anymore), raise your heel as much as you can by squeezing your calf while creating resistance by pushing your hands to the top of the doorframe (This is the top of the rep).
4. Constantly move your heels between these two points until fatigue.
