calves are like a big dick, either you have it or you don't
for me it works best to train them like all other muscles, i.e. heavy weight low reps. best is standing calf raises.
you want to train the fast twitch fibers, only they make a muscle grow., that's why they need heavy weight, low reps.
problem for many is that there are not so many fast twitch fibers in the calves. if you don't have them it's almost impossible to grow your calfes.
just forget the nonsense that they have to be trained more often and with more sets than any other muscle.
