To me flex needs to be careful with his waist, he's short enough as it is, he does not need to play the size game right now. He will just get blocky, as for his back, there's not much he can do about it, if he does not have a good back at 22 years of age, he never well, its just his genetics. All he can do is thicken it up and add more detail to it. His legs our his key points, but has to bring up his chest, arms and back to match is legs.. He's going all out, to try and be # 1, alot of guys will do what it takes at all cost to be #1. Alot guys burn out in the process, again look at Ronnie, he did not start going hard on drugs until his mid 30's.. Now look at him, but i guess he has freaky genetics to his advantage. I don't know why some guys our in such a hurry to be # 1 at such a young age? I doubt there will ever be a Mr O champ in there early to mid 20's.. You peak in your 30's anyways, so save all the hardcore drug usage tell then, and let your body grow noramlly through your 20's.. Just my 2 cents.
