The International Natural Bodybuilding & Fitness Federation (INBF)

With a close affiliation with the NANBF who adhere to the same strict standards of drug-screening and show quality. Members of the two federations can choose from over 50 competitions annually with one membership card.

This tremendous growth is due to a number of factors. The gateway to the Pro Natural WNBF is an obvious reason.

But there is more to the INBF: There are no politics involved in the judging process, in the promotion of competitors or in the "control" of where athletes can compete. If they wish to, INBF members can compete wherever they please. It is their choice. But once they've had the opportunity to compete in the INBF/NANBF network of shows, why would they want to compete anywhere else anyway?
