both , I remember him doing waits on one of his training vid not heavy but med to light heavy lots of reps.
He did before the Ruiz fight but that doesn't say much, he was bulking up to a higher weight. I don't know whether he did it before though.
I remember Lampley saying once that Jones claimed that he didnt use weights but did pull ups, push ups and bag punching for that physique. He did lift weights to fight Ruiz.
dont try to change my post up. Im sayin to prove the steroids thing RJ was always ripped, his muscle structure is like anyone we have seen. that whole steroids things was alleged. He did it by hardwork
if he says he didn't use weights at all, that means he probably did...no smart fighter gives away all his techniques, and i know for a fact that light weight training helps muscle endurance, if not for size...
