Kai is a solid bodybuilder and has nothing to be ashamed of. He'll keep working at it and pushing forward because he loves it.
His gut can be controlled but unfortunately, I don't see that waist line coming in. Also, his image is badly tainted and even though I think he is a better bodybuilder than Heath, the IFBB will never have him as the representation of the sport. He'd have to TRULY DOMINATE in Ronniesque fashion where not a sole in the world could argue against him being the best for him to have a shot at being Mr. O.
Still, if he's smart, he can maximize his opportunity and set his financial future up if he wanted to and should stay in bodybuilding because I don't know where else he'll have an opportunity to do that. G4P? Sure, but damn, is that what you really want to make your living from if you don't have to?
