You are literally talking from your ass and you are delusional if you think Ruiz being as fat as he is is beneficial whatsoever.
There is a difference in being shredded and not being morbidly obese.
Weight is power......so if he loses his weight, his power might take a hit....again I have no idea if he can develop muscle or if that's pretty much "it" for him(so if he can gain muscle, then losing fat weight might not hurt along as muscle replaces some of it).......also his speed is amazing, I doubt he would get much faster if he lost weight, enough that it will be worth losing the power....That's the only benefit I see...but I agree with the idea that he should lose weight.
All Im saying is, don't expect abs on Andy Ruiz.......I don't think his body can maintain muscle and be that shredded, while doing boxing....his body simply isn't like that that......Im sure he can lose more lbs and get "in-shape", but no way is he getting super lean....at best he ends up as lean as Kelvin Gastelum @ WW, but I highly doubt that.
