NANBF Bikini Guidelines


The Bikini category is for women who have a healthy-looking, toned body with good symmetry and balance. Bikini competitors should have good posture and stage presence, while maintaining a feminine look. They should not display an abundance of muscle size.


Competitors will compete in a two-piece suit and high heels. The bottom of the suit must be v-shaped. No thongs are permitted. All suits must be in good taste. Athletes will be warned about improper suits and are advised to contact show promoter if you are concerned your suit does not meet specifications. The fronts of the suits should not be too low and must be constructed higher. Competitors may wear jewelry.


Starting in 2020, bikini competitors are permitted to crossover to Figure, Women’s Physique or Women's Bodybuilding.


The use of performance-enhancing substances is never permitted. All competitors must successfully pass a polygraph screen prior to competition.

Judging criteria

A specific level of muscularity or leanness is not sought after for NANBF Bikini competition. Judging is based on having an overall healthy-looking toned body with good symmetry, shape, fullness, balance, and proportion with good poise, posture, confidence, stage presence, and comfortable presentation. Other factors that can affect overall appearance are skin tone, complexion, suit fit, hair, and make-up. Bikini competitors should not display an abundance of muscle size, deep muscle separation, or muscle striations.

Group comparisons

Each class is brought to front center stage and is guided through quarter turns to display physiques from all sides. The front and rear stances are to be with one hand on a hip with the opposite hip extended outward. Side stances will have the backhand on hip elbow rotated forward and front shoulder and arm open to the judges.  Stances should be fairly relaxed. Competitors should not appear to be flexing. The leg on the side with hand on hip should have toes angled outward slightly while the opposite legs toes should point straight forward.

Individual presentation and stage walks

The individual presentation portion is a stage walk.  This portion of the show is for the crowd and gives the competitor a chance to win a "Best Presenter" or "Best Poser" award.  Competitors walk out to House music of the promoter's choice and perform a T-walk or the L-walk.


T-walks consists of walking out from rear center stage, do a single pose, then walk to front center stage turn and walk to stage left and do two poses, then walk to stage right do two poses, then walk to the front center of the stage doing the final two poses then exit the stage.  For the L-walk, walk from center stage to either right or left stage. Do the same amount of poses in three spots in a straight line, then leave the stage. *This walk may be modified at the Promoters discretion.


Individual presentations should be done tastefully and be conducive to a family atmosphere. Bodybuilding-type poses, fitness moves (like push-ups) and costumes/props should be avoided.
