people focus to much on the top end portion of the contraction pump away with a short choppy motion or use entirely to much weight. what people fail to realize is that when we walk around we work them at the top end 99% of the time and miss out on the bottom end work from the stretch position. so next time you hit calves go ahead and do your 10 or so full range reps then focus another 10-20 reps that are from the full stretch to flat only. i do full sets this way only myself and they are brutal and make them grow like nothing else. that and lots of failure work. they can also be trained very very frequently just like traps forearms and abs
