Stand upright in a calf raise machine, position the pads on your shoulder and your forefoot on top of the platform.
2. Slowly flex your ankle to lower your heel (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 (This is the top of the rep).
4. Constantly move your heel between these two points until fatique.
5. Once finished, repeat the steps with your other leg.
