ok, so i've seen the rotation recommended for insanity on the other post and my question is: Do you think doing such an intense workout 5 days per week would lead to overtraining? I'm thinking that mabe the workouts should be done everyother day due to the intensity. What are your thoughts? I have read that metabolic workouts like these are hard on the central nervous system and its imparative to only perform such workouts no more than 3 times per week.
