I'm not bagging on Jon like he has to drop a ton, but 240 is probably a little too much, especially for someone as young as (I think) he is. Exercise is one part, eating another, and some is just plain genetics. I work out like a mutha in the gym, plus sticktime 2 or 3 times a week, and I'm still 220 (at 5'8"), but part of that is due to being a 47-year-old endomorph with 80% slow-twitch muscle fibers ..... i.e., I couldn't be a hockey stud even if I had 3 hours a day of icetime and Toe Blake coaching me.
BBO that is my old man and he is just busting balls
