User blog comment:VeryUnknownFan/How do you think Racial Characters are handled on the Show?/@comment-24245380-20140112220350/@comment-24600224-20140113045050

I don't think there's racism but if you ask me, the level of musculanity and power in those boys ranges as follows. (This is my personal assessment, by the way):

Lightning > Alejandro > Justin > Geoff > DJ

I feel that Lightning is committed to having the strongest body possible, where as Alejandro and Justin mostly just want to look good and feel good. Geoff is likely just muscular as a result of his partying lifestyle and DJ is just naturally big boned.
