I just hit calves for you man. Did standing calf raises on a 10cm thick book 3 sets of 12 ONE foot at a time with my bodyweight. My calves are 15 inches

Hey, my calves are the same size, it's good size believe me.

I think I would fail with those one legged calf raises, I have never done them because they are so hard.

Stronger calves might assist in the squat and make one faster runner, I should do them.
