He look huge but his abdomen is starting to get very thick and distended, his once aesthetic appearance is all but gone.
Shy and introverted people usually have a coping mechanism to allow themselves to perform in public. E.g. A surprisingly large proportion of actors actually had speech and shyness problems as kids (although the majority are still attention whores). The coping mechanism is usually about having a persona for the world that is somewhat removed from themselves thus allowing them to do simple things in front of an audience.
On Kai's posing: I've always felt that Kai's posing detracts from his physique as it doesn't effectively display it. END OF STORY. A posing routine can be entertaining but not at the expensive of displaying his physique. Now a guest posing routine you can do just about anything that gets the crowd cheering, you are there to entertain, not compete. But guest posings are also about developing a fan base and creating a profile in the sport that is respected and admired so that fans and judges come into the events that you are competing in looking for you to be placed well. How many times have we seen relative unknowns have great physiques get overlooked in the judging? Plenty of times, simply because everyone in attendance has a list of competitors that they are expecting to be at the top of the list, the unknowns then have to compete to push in at the end of that list.
Basically in this day and age of highly accessible media, you can't afford to do something that detracts from your profile, whether that be signing pics or guest posings. Kai has built a profile on his headstands and stripper styled routines. I don't think it does the sport any good, but it hasn't hurt Kai thus-far (much to my chagrin).
Nothing brings as many polarized opinions as a kai thread.
His routines are entertaining, no doubt about that. But when competing, he should pay more attention to how to display his physique properly; hold his poses longer and make some minor adjustments to some of his poses. On top of that, he should NOT get any heavier than he already is. Getting better is not always the same as getting bigger and bigger.
Quite the entertainer this man.
All obvious comments about routine aside, there is one thing I noticed..
His rear lat spread he actually seems to do properly and really show the width and thickness that his lats have. Before it almost looked liked he was trying to hide them, which was a shame because his lats come to mind first when I think of whose are the best.
