heres something i used to really get my calves to grow
its all about the negative...on your last set of standing calf raises...hold the negative for 15-20 seconds..and then the positive part of the movement for 15-20 more....that will burn the living hell out of your calves
also if you have access to a leg press machine, try blowtorch calve presses...3 sets of 100 reps...with some solid ass weight on there...approx half of your max leg press...that will have you screaming for mercy by the end of the 3rd set
then finish it off with the bodyweight raises..and your legs will be shaking like the chicks in rap videos
