My utmost worst was 375 @ 38% bf. It was during my double knee surgeries in 2K3 & 2K4. Sure, my strength was enormous but I looked like a piggy piggy. By 2K7, I got serious with my training and gear use and now I'm a much leaner 260 @ 20% (for now).
Recently, I cracked a joke with Scot Mendelson when he was telling us that his heaviest was 360. I told him, "Mine was 375."
He then turned to me and said, "Yeah, but I had abs."
I replied, "Well, I did too. I just kept them my six pack tucked away behind my keg." LOL
