Yea a guy like Dejaun Blair is an energy guy and he has around 12%. I'd still think under 10% would have more benefits though because you aren't carrying around that extra weight. I think 8% is a great place to be. 8% fat you will be ripped but not at a point where you have to worry about internal organs getting messed up if you get nailed in the gut lol. 4% is ridiculously low.
Aaron Brooks clocked in at 2.7 though coming out of Oregon tho
and he seems to be doing alright lol. Man WTF tho I mean I know he is always running around but good lord his metabolism must have an unquenchable thirst for calories lol.
