I have a question about HIT, I know, like I don't have enough questions already!!! But my question comes from the Matt Brzycki book "A Practical approach to Strength Training". In his book he says that a muscle that hasn't been worked in a 96 hour period, begins to lose both strength and size. That worries me in that if in fact I do the HIT program, I would be only hitting each bodypart once a week. Thats a bit longer than 96 hours. If I follow an upper/lower split then at least I would hit each BP once every 4-5 days. I follow a 3 day a week program (M-W-F) Please help me to believe that once a week is enough for the muscle to grow and become stronger. Kinda worried here My routine that I have started is like this:
Monday-Push group (Chest/shoulders/triceps)
Friday-Pull group (Back/traps/biceps/forearms)
I am worried this would not be enough according to Matt's Book.
