Calves are unlike most other body parts- this part seem to thrive on high volume workouts. This is why it is recommended to keep the reps at a high level. It is because they’re used every day when we walk, so you really have to work with them in order for them to grow.
A lot of people feel that by angling their feet differently they can act on the different muscles in the calves. It can be effective, but is certainly not the best way. The best method is to change your stance- rotate between using a wide and a narrow stance. A narrow stance stresses the outer head of the calf; a wider stance places more force on the inner calf.
- Standing calf-raises: Great way to work the calves. Change the rep routine around constantly.
- Donkey raises: An old and efficient exercise.
- Calf-machine: An alternative to donkey raises
