This exercise workes the muscles of the upper calf. You may work your calves slightly faster than other body parts. Be careful to keep the movement controlled.
How to do:
1. Using the leg press machine, place your toes and the balls of your feet on the edge of the platform, so your heels rise in mid-air.
2. keep your knees locked.
3. Push the platform by extending the foot (toes higher than heels, calves contracted).
4. Lower the platform by contracting your foot (toes lower than heels, calves stretched).
5. Be very careful not to bounce the weight.
6. Repeat until failure or until you have completed the desired number of repetitions.
