but he looks like shit doing it
Yes, but bodybuilding puts greater precedence on muscle size than conditioning.
Both aspects of the physique, mass and conditioning, do not carry equal value.
It makes sense because it takes longer to build a lot of quality muscle than it does to take lasix and diet for weeks. Anyone can be "off" because they miscalculated the time it takes to get dry; however, you can't take away the years spent building superior muscle mass.
At the end of the day, it's a bodybuilding contest.
great muscle mass + average conditioning > average muscle mass with great conditioning.
For this reason, Jay deserves the title.
