hello, i am helping a friend out to create a free "bodybuilding 101" kinda thing. I'm responsible for the layout not the content but he asked my advice on something. He wants to break down the 4 essential components of bodybuilding training. He says they are:
Progressive strength training / Nutrition & diet / Cardio / Mobility & flexibility
(of course you can see he's skipping the mental aspects such as determination and discipline)
Personally i don't find that mobility and flexibility are Essential (apart from warm-ups and cool downs). Just looking for some other opinions.
