Damn it. I keep seeing more and more of these. Are bodybuilders really in fact so puny? 

Just as an FYI for those wondering, Busta Rhymes (Trevor) has been bodybuilding for over 10 years (not competing) under the tutelage of Victor Muñoz (Victor Martinez's long time bodybuilding trainer). Trevor is actually pretty big in person (not height, but muscle mass wise). It doesn't come to me as a surprise that he towers over Kai, but if Kai were to remove his top, it's game over. Looks can be deceiving, that said, Busta is actually, as inner city kids would say, "bodied up".
The math makes sense, get trained by a guy that prepares IFBB pros and be around IFBB pros and certain "things" tend to rub off.

This was filmed over 8 years ago and you can see a cameo appearance by Trevor around the 2:30-2:33 time mark:
