The link between weight, body fat and performance is often poorly-understood, so consider this a quick and interesting lesson. Do you recognize the basketball player in the photo to the left? Probably not, since he never got to play in the NBA.
His name is Chris Marcus, a 7'1", 300-lb., 23.1% body fat college player. Anyone remember James Lang, Dexter Pittman, Darrell Johns and Marco Killingsworth? They were in the high-teens and low 20's with regard to body fat. The extra baggage may have played a role in their anonymity among out readers.
