Musclemania is a federation of it’s own. Same as NPC, NABF (North American Bodybuilding Federation), ANBC (American Natural Bodybuilding Conference), etc.
I've watched the Musclemania's shows and basically (IMO), they're trying to put bodybuilding into a "showbizzy" like setting. You know, fancy posing suits, funkier music - stuff like that. I know that the NPC has allowed competitors to wear jewelry and fancier posing suits for the evening show - but the morning shows (prejudging) it's still all business. I'm not a big fan of Musclemania. I still prefer the competition that is provided in the NPC. I still believe the NPC provides the best in competition (judging, competitors, promoters). But that's my opinion.
There was a promoter that "jumped ship" from the NPC and was busily bad mouthing the organization every chance he got, even sending me an email about this negative feelings as well as promoting his new "natural" organization. I gotta say that this promoter is also a national level competitor and one of the biggest users of synthol on the planet (as well as any other androgen) - he's cartoony big now. Anyways, I didn't "jump ship" and I won't ever. But he keeps sending me flyers of upcoming shows within this "natural" organization.
I think Musclemania is good for a competitor who is top ranked regionally and needs to gain some exposure nationally. You would compete there, get useto a big crowd, TV coverage, etc. and then go on and compete in a national level NPC contest. Just my thoughts...
