You thought wrong. Listed as 287 in 2003 and 296 in 2004 and was said to have been over 300 pounds at the 2004 Grand Prix shows.
I wonder why everyone talks about how ungodly huge he was in 2003 and not 2004 or maybe I have that wrong. I read where even Jay conceded defeat when he saw Ronnie pumping up in 2003.
Either way there's never been a human being packing as much lean muscle mass as Coleman.
