If you seriously believe he got like that using ONLY his body weight then you've just been'd something serious. You can tell by the amount of muscle mass one has usually if they use weights or just do purely calisthenics. A lot of cats his size though have MASTERED the calisthenics, and really have no need for weight work anymore, plus to stay cut AND lose weight more efficiently (b/c weights will add muscle weight), they tout calisthenics and people that don't know any better are misinformed into believing that they can get like this with their body weight, and a few bars alone.
No.
The more I look at calisthenics the more I think that hannibal has to be using weights or at least lifted heavy a good amount before doing calisthenics; he seems way too huge for it to be built of pure bodyweight.
People who train pure calisthenics are usually lean & muscular not huge & muscular
