How do I register for an event?

Find the event on the website by clicking here.  Click on the link to the website for that particular competition.  Some shows require online registration and some will take mail in applications.  Send in your application and entry fees to the address on the application.  At this point, some promoters will schedule you for a polygraph and others will require you to contact the polygraph examiner to schedule an appointment.  The next step is to register for your INBF Membership Card.  Your card will be presented to you at check-in for your selected competition.


What categories are offered?

  • Bikini
  • Bodybuilding – Men
  • Bodybuilding – Women
  • Figure
  • Fit Body
  • Men’s Physique

The criteria for each category is located here.


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.

What is the definition of Junior?

20 – 23 years of age


To compete in an INBF event, an athlete must have a current INBF membership.  Memberships are active for 11 months (expiration is the end of the month prior to competition month the next year).  For example if you compete on 7/16/16, your membership will expire 6/30/17.  You may compete in any INBF event during this time frame.  All affiliate membership cards are accepted by the INBF competitions in the U.S.

International Athletes

International athletes are welcome to compete with the INBF (Amateur Affiliate of the WNBF in the United States), or in an affiliate country as long as there is not a WNBF affiliated federation in their country.  If a WNBF affiliate has been established in your country you must purchase that organizations membership card and compete within your country.  To submit a question please do so via our contact page here.


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 polygraph 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 examiners will require you to submit pre-screening 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.

Banned Substances/Prescribed Medications:

Please read the banned substance list thoroughly prior to submitting a supplement, or prescription medication question by clicking the envelope below

* An athlete who has failed a polygraph or urinalysis test with any federation must divulge this information prior to registering with the INBF.   Such a failure that regards any INBF banned substance will result in a 10 year suspension.
