So if you trained every day you wouldn't get any muscle growth.
That's not what I'm saying, closer to what silverback is saying.
I should have said "Your muscles are STILL/ALSO growing on off days" implying you still need adaquet protein on these days.
Having said that, I don't think any decent programs have beginners OR advanced lifters hitting the exact same muscles 7 days a week, that would mean a 7 day full body program.... Who does that??
