I am a firm believer in burning out the calves I train them twice a week 8 to 12 sets with reps of 15 to 20 in each set, I always train calves before I start my intense training session due to fact that when I am done after beating myself up there is no way I will be able to train my calves with that burning intense feeling of satisfaction.
