- Donkey calf raises - 5 sets of 15, with 30 seconds rest between sets.
- Seated calf raises - One drop set (100 x 12, 75 x 6, 50 x 6, 25 x 6, then just the machine weight x 25).
- Deep stretching - 3 sets of 30 seconds each calf.
The higher volume has added almost 3/4 of an inch to my calves in the last couple months.
Of course, sprints, hills, stairs, prowler work kills them too :)))
