Jay Cutler really has some good methods on calves.
Especially the 1.5 rep technique.
Do the full rep come down slightly then push all the way back up.
My calves need a lot of work to grow.
I do calves on chest day.. not on leg day.
I do 5-6 sets of heavy standing calve raises. I go heavier each set and reduce reps... first set about 20 reps and last set about 8 reps. (I use the 1.5 rep technique for first 3-4 sets.
Then I do 4 sets of seated calve raises.
12 reps a set... the last 2 set I go to total failure with partial reps.
Anyways, this has really helped my calves.
I also try and sneak a bit of calves in on leg day. Like after each set on the leg press/hack squat machine, I finish off with calve raises.
