Im keen to see his gas tank, adding weight comes at a price when fighting especially in your mid 30s, Im a Jones fan and hope he wins but he's added a lot of weight and been out for years not weeks, heavyweights fight at a slower speed which will help, but there are lots of factors here to observe, he's clearly sweating more and breathing heavier when training, I just hope he hasn't overdone it with the weight I would have liked to seen him 10 pounds lighter, but maybe he wants or needs the weight to wrestle or for take down defence, his light heavy body and skill set plus ten pounds without cutting weight was all he needed in my opinion, he's about ten pounds over where that would have put him, hopefully it doesnt effect him negatively.
