You might look better, but please think of the functionality.

Having bigger muscles will hold you back in the ring. Great fighters in history haven't built muscle to be good in the ring. The muscle that they did have came naturally with their boxing training. Mike Tyson didn't lift weights in his prime. More muscle equates to the requirement of more oxygen. Watch Bob Sapp fight to see how quick the big oaf gasses.

Also, while we're at it, screw your friends. They're not there to compete with you. If they're stronger, and you have the naturally boxing abilities of a decent fighters, well their strength won't help them out very much if you want to put a whooping on them.
