6 days per week after my workout.
Standing Calf machine raises 4 sets to failure 300 lbs (as high as it goes)
45degrees donkey calf raise machine 4 sets to failure with 180lbs
seated calf raises 4 sets of failure with 90 pounds
instead of banging out quick reps and couting as fast as possible to the last rep, i just bang them out as much as i can until i cant even twitch them. i started this for about a week and i feel it getting stronger and i just cant wait til theyre not one of my weak points anymore.
i agree with high reps and low reps with calves. sometimes ill go really heavy to failure, sometime ill put a little less weight and do a couple more reps, but definitely train calves til failure. they get worked every day you walk, they need special attention for growth, imo.
