For INBF Pro Qualifying events, athletes may enter Open OR Novice, NOT BOTH. Crossovers may occur between an age division and Open or Novice, or between categories such as Figure & Fit Body, or Men’s Physique and Bodybuilding.

Why do you not allow novice to open crossovers?

The INBF does not allow this because the divisions are a totally different mind set. Novice athletes should have a goal to gain competition experience, and do the best they can. By not allowing Open competitors to cross back into Novice, this gives people the best chance to compete with other beginners. It makes for a fair playing field for real Novice competitors. Open class competitors should have competed before, and are working towards winning Pro status.

What is the definition of Novice?

Novice competitors are either first time competitors, someone who has competed and has not placed, or has not placed top three in an Open class. If you win a Novice class, you are then required to compete in an Open division.


Global union membership is valid for 11 months after enrollment.

International Athletes

International competitors can compete in local competitions if the country is a member of the union.


Am I required to take the polygraph?

Yes, we require all competitors to take and pass an intense polygraph. This test is good for 6 weeks for amateurs and 2 weeks for pros. If you are entering another INBF or WNBF event please let the show promoter know you have been tested and they will confirm this with a WNBF official.

Can I use another organizations polygraph test?

No, we require all competitors to test directly with us. Our banned substance list is more stringent than other organizations, and we have very high standards for our licensed professionals.

How long does the polygraph take?

The polygraph examination itself is not a long process, usually completed on Thursday & Friday prior to a Saturday competition. The pre-screening, completing the athlete questionnaire, and multiple pre-interviews do take significantly more time. All of this information is necessary for us to gather in order to make our polygraph process more valid. You should plan to arrive at least 30 minutes before your scheduled appointment time to fill out paperwork. Some testers will require you to submit paperwork in advance. A valid ID, drivers license, or passport also needs to be provided to the polygraph examiner.

Am I required to urine test?

If you are a Professional member, we can and will ask competitors to submit a urine specimen unannounced. If you are at a show, all prize money winners and also pro card winners are required to urine test immediately after leaving the stage from awards. All competitors are required to test in a posing suit and will not be allowed to bring anything into the testing area.
