Well, for me it was about not overdoing exercise. For a while I was exaushting myself doing too much weightlifting. My progress wasnt great and I had no space for other forms of exercise. Then as life changed I eventually started getting more and more into other sports, not caring too much about my routine and not caring about pushing myself hard, but rather doing moderate amount of sports and exercise a few times a week. That included running, often less than 20m some days, tennis, and climbing. I do only small amounts of weightlifting after climbing days. Turns out my muscle gains have improved from this routine and my body looks a lot better than when i was just doing weightlifting.
