Sorry, should have clarified. When I said fight game I was specifically talking about MMA. It's clearly a prohibitive body type to have in MMA. The majority of top MMA fighters have the will power to get in more aesthetically pleasing shape and would do so if they thought it was useful. Reminds me of strong men. Brian Shaw, Halfthor Bjornson, Eddie Hall, none of these top guys are super cut.. at least not when they are competing.
