UFC heavyweight contender Roy Nelson has never been the poster boy for a fitness-minded physique, and he believes there is a reason he doesn’t look like most UFC fighters. Nelson doesn’t sport six-pack abs.  He often rubs his oversized midsection when celebrating victory, embracing the fact that his body doesn’t fit the typical fighter’s form. “People that tend to be in our sport tend to abuse PEDs or performance enhancing drugs.
