Haha too fat at 18%? Man when I came into high school I was about 24%. My sophomore year the only thing that changed was I went from being a 170 lb 24% to a 225 lb 22% haha.
Very nice on the leg PR's too man, being a little shorter can give you that extra push to throw up big weight like that!
I was the opposite of you though, I benched 335 lbs for one rep and could only squat less than that........luckily I've evened out a little more lol
