Quick question for those more advanced than I. I read something that indicates that muscles usually need an average of 48 hours recovery time. It continues by stating that "Advanced," not beginner or intermediate trainers, should incorporate all muscle groups in one day. As for the second part, whatever. I couldn't get a really good full-body workout in one day without some crack in my diet. My question is this. I have been training pretty hard on a 5-day split. The progress is there, but I wish I could move things along a bit more aggressively. Is it safe to think that because an isolated muscle needs roughly 48 hours to recover and rebuild that I could work out the isolated muscle not just once a week but twice a week instead?
I'm obviously looking to hear what more advanced trainers have heard or tried themselves and if this makes sense. If the food intake is there and other supplements e.g. essential amino's, creatine, AKG, carbs is in line, would it make sense to go ahead and step away from the once a week routine?
Thank you in advance for answering this.
