Also kai is closest to ronnie in terms of their apporach to lifting, both are very sober and focussed, and they ave very similar genetics... their legs come out of their hips in the same weird way, dunno how to describe this, their quads also start really high up allowing them to have huge huge thighs, their arms are the same, big heavy thick hanging tris and a sharp peak on the bicep. Very similar structures i'd say
