Kai is the best trainer I think I've ever seen, he blows guys like charles glass out of the water, dude actually understands every single exercise and the purpose behind it and what the proper mechanics are!!! a trainer like this would shave years off people's bodybuilding dreams, he could probably transform your body in 2 months with proper training and no wasted exercises.
Also! Kai mentions a getbig phrase 'no homo' around 9:40
