Stomach was a weakness for me. Ruined his look starting from around 2001.
He pushed bodybuilding pretty much to the limit, which I think serves well in letting people know what can happen if you just keep trying to gain size, as far as the waist growing and eventually maybe even getting hurt. In that sense not only was he a pioneer, but it's a good lesson for current/next generation of bodybuilders to learn from.
I prefer his 98-01 look as well, but he was pretty damn big everywhere else, so I guess it's all good.
Man suffers only because he takes seriously what the Gods made for fun
