I can remember working out at the same time with Pat Swilling and thinking he really wasn't that much bigger than me. He may have had me by 15 or 20 pounds at the most and wasn't that huge a guy. However, when it came time to bench, he would just endlessly toss up weights that I was struggling to get 6 or 7 reps with. It was humiliating. He wasn't that big, but he had some fast twitch muscle fiber. I can tell you that.
