Should I train for pure size (hypertrophy) or can I train for athleticism. The fittest I've been was when I was doing a kettlebell program but I wasn't as muscular as I am now. I don't wanna be 'all show and no go' but I realize that size helps with confidence especially when I'm in public. When I'm playing basketball, however, I can feel that I'm not as functional and mobile.. Do rep ranges matter when it comes to T boosting (low rep range vs hypertrophy rep range)? It's hard to choose whether I want to train to play sports better or to look better.. It seems that you can't mix both with optimum results
