i bet the real reason is that you dont train your ass hard enough, you should be inspired by 8 time mr olympia - ronnie coleman
My ass is one of my better bodyparts. Girls in the club pinch it all the time.
maybe he could answer the age old question of what the hell happened to Ronnies calves?
Crappy form, not enough volume, no mind muscle connection. If you notice Ronnie only does calves after or before a workout for 5 minutes doing one exercises and just bouncing the weight in a 1 inch range of motion. Quality contraction my friend.
