Also check out Functionally Correct Calves in issue 268, might give you some ideas.
I got good results from training my calves twice per week, one heavy and one light workout.
Wo 1. Standing and seated calfraises for 12-15 sets, reps 3-6.
Wo 2. Standing calfraise-donkey calfraise-jumping. All on one leg, bodyweight only. Maximum reps! Do your weak leg first. Rest 15-20 sec and do your other leg. 3-4 sets total (per leg). Rest a few minutes and continue with calfraises in legpress machine, 3-5 set 10-15 reps.
Importent, do all reps nice and slow, let the muscle work. Tempo 1211.
Start with a lower amount of sets and work up gradually, trust me on that one, I learnt the hard way!!
Seated calfraise w/o machint. Easy, sit on a bench, balance a dumbell on your knee, slide your foot back untill the heal lifts from the floor. Rep away!!
Another thing I found important when training is consistency, keep hammering those calves and they will grow. Change program every three weeks. Have two programs that you alternate.
