Calves have always been the one muscle that has never grown for me. I've always used a similar approach to training them as any other muscle group. 8-12 reps and have experimented with anywhere from once a week to daily training. nothing has done a damn thing for them. Yesterday i went on a short 1.5 mile up hill hike and today my calves are sorer than they've ever been by training them. I also had a insane pump while walking that exceeded anything i get from training them. This makes me question if the key to calves is high volume to ultra high volume. I've never experimented with high reps for any length of time and thinking it might be worth a shot. what do you guys think?
