Yes, that guy is known as CaptnJ, and his feats of strength are
really impressive.
That said, some bodybuilders started out as weightlifters. Arnold
Schwarzenegger and Franco Columbo started out as weightlifters.
Same goes for Ronnie Coleman and Johnnie Jackson. There is a large
amount of carryover, but IMO, you have to specialise to be really
successful in either bodybuilding and weightlifting.
