Fred Hatfield advocates something called the Zig Zag diet where you eat way over maintenance on training days and below on rest days. He claims it works great and has used it on old bodybuilders. I have never tried it myself. I remember listening to it in a pod cast. I’ll see if I can find it.
MAJOR!!! problem I see with this is your healing building muscle or your OFF days. So during a bulk or even cut dropping cals below Maint will not hinder not just growth but simple recover and progress that allow progression in the gym.
I usually naturally eat more on training days even more so on say squat and DL just do to being ravenous but off days during bulks im sure to keep it above as well just not the simple carbs more from fruits, oats veggies. Plenty of fats and protein.
I agree. I don’t follow it.
