if you don't want or need rest days you ain't training hard enough. end of story.
somewhat true but what I am trying to get across is there are so many muscles and as bodybuilders there is always areas that need improvement. I think 5 days a week is plenty but you could def use the other 2 days to work on fine tunning certain muscle areas you might be lagging or are not up to par. The few days where my work-outs are not as intense are just days where I catch up on these lagging bodyparts even if it's just forarms or maybe more work in the glutes. Now big muscle groups are diffrent but you can definately knit-pick and always find something to work on and improve.
Plus I always think it's best to work-out everyday to keep the fat burning effect going on. I think taking a few days off can slow your progress down. hell even doing a nice cardio session is fine along with a small work-out. I do agree training 7 days a week balls to the wall is not necessary! If somebody has to do that then your correct something is wrong. Alot of bodybuilders lie! The bodybuilders who are coming up and hungry train twice a day. zIt's actually the top bodybuilders who don't trai as often due to their booked schedules and all the traveling they do. Right now their is a freak NPC competitor who is training 2 times daily trying to get that pro card.
No such thing as over-training when your using anabolic steroids,HGH,anchileries and other peptides.
