Is this awful? I have a friend who swears by it saying that just because the calnder revolves around weeks doesent mean your muscles should. He uses very high volume workouts upwards of 30 sets sometimes for major msucle groups and up to about 20 on smaller ones and believes the only way for him to fully recover session to session is to take 10 days between his muscles. He also told me since he seperates all his muscles in his workouts he gets a slight workout on muscles not being worked that day due to his high volume when he works secondary muscles in his excercises, for example on his triceps day his chet gets a slight workout form the 6 sets of dips he does and so on. He believes thus if there is any undertraiining going on this solves the problem. I actually think this is a pretty cool conept and may consider giving it a shot. I am curious to see what you guys believe.
