also, experiment with your calf workout. some people grow faster with lower reps and heavy weight...others do better with high reps and less weight.
then you have people like me, who have genetically larger, stronger calves. Even though I've been lazy for a year now, I could walk up to the standing calf raise machine, pop the pin at the bottom (something like 490 lbs) and go for 3 sets of 20 reps without a problem. Thus, I tend to skip calves in my leg workouts, as I need to bring my quads up to speed.
