kai is "aesthetic"
in this context, the word "aesthetic" means beautiful.
kai is a midget who looks like he's had four vertebrae removed. he has the ugliest face in bodybuilding at present.* his waist is the size of a planet. his arms are very oddly shaped. i think tbombz is right about wolf having badly shaped (though large) arms, but kai's are just as bad. Phil has pleasing if suspiciously large arms. Ronnie had awesome looking arms. Kevin and shawn had beautiful arms. Kai's biceps are very short and look like a slime ball that has gained sentience and is trying to escape. His quads, while absolutely enormous and striated, are the definition of ugly:
they look almost square from the front, short vastus intermedius / rectus femoris, and monstrous sartorious, and even his medialis looks like some poorly squeezed dollop of toothpaste in this shot.
this is what an aesthetic thigh looks like:
also, kai's traps appear puny from behind.
phil has "aesthetic" muscles, bones, skin, etc. same as victor, brandon curry, lionel beyeke, etc.
but kai?!?!
*probably not true but i can't be bothered to think hard about this
