Come on bro, can you not see the visual difference. Bolo is way more compact, his muscles are twice Van Dammes size, not even close.
Bolo and Van Damm are about the same height. Bolo was bulky--bloofy bulky, with saggy pecs. Sloping shoulders. He lacked cuts---except when he flexed his pecs (very good split in his pec reminiscent of Franco). Had some ab definition.
Van Damm always stayed pretty lean, even in his more muscular days. I'd say for Bolo to diet down, would be harder on him than Van Damm gaining weight.
Muscle-wise, you can't really tell with Bolo, as he was bulky, and never was diet down.
*He could move, though. I liked all the movies he was in, because it showed that a Bber could move quickly, and effortlessly.
