Natural Bodybuilding Federation Bulgaria — Drug-Free Sport, Lifetime Values
The Natural Bodybuilding Federation Bulgaria (NBFB) was founded to provide Bulgarian athletes with a fair, drug-free competitive platform rooted in integrity. We believe the human body, trained through discipline, nutrition, and relentless work, is extraordinary on its own.
From Sofia to Plovdiv, Varna to Burgas — we unite competitors, coaches, and fans across the nation under one banner: natural sport, pure achievement. Our federation is officially registered and operates in full compliance with national sports law and international anti-doping standards.
Whether you are stepping on stage for the first time or a seasoned champion, NBFB is your home.
We uphold the strictest anti-doping protocols. Every competitor is tested, every title is earned cleanly.
Men, women, juniors, and masters — every Bulgarian has a division and a stage to compete on.
We provide seminars, coaching certifications, and nutritional resources to elevate the sport nationwide.
NBFB athletes represent Bulgaria in INBA, WABBA, and NANBF international championships.
The most muscular of the men's categories, scored evenly on symmetry and muscularity across two rounds. Because athletes are compared throughout, posing stamina and holding a complete, balanced, conditioned physique matter from start to finish.
Criteria, rounds and poses are summarised from the 2026 WNBF Judging Criteria and Rules. NBFB events are run to WNBF natural standards; exact classes and format for each show are confirmed in the official athlete packet.
Register for This DivisionA tribute to bodybuilding's golden era — not simply a smaller category. Symmetry leads at 50%, with the rest split between muscularity (25%) and directly-judged presentation (25%), so an expertly presented, symmetrical physique will beat a bigger one.

Register for This DivisionThe second-most muscular women's category — more muscular than Figure, but weighted toward symmetry and directly-judged posing. Conditioned with separation across all groups, without pursuing size or leanness at the expense of balance.

Register for This DivisionJudged equally on symmetry and muscle tone with presentation as a key component. More muscular than Bikini but less than Fit Body or Women's Bodybuilding — lean and hard with clear separation, never a soft look. Judged through quarter turns, with no muscularity poses.

Register for This DivisionFocuses on presentation, balance and category-specific development — softer than Figure but lean with separation, and with the glutes, back and shoulders emphasised. Judged to the international standard, with presentation forming half the score and a key tie-breaker.

Register for This DivisionEvery NBFB athlete is subject to drug testing. We do not make exceptions. Our testing protocols are among the strictest in Bulgarian sport, ensuring every trophy, every medal, and every title is earned through hard work alone.
Every competitor must complete a polygraph examination before stepping on stage. No exceptions, no opt-outs — this applies to all athletes in every division.
Biological testing at NBFB competitions is conducted by WADA, the World Anti-Doping Agency, following their accredited protocol. Both urinalysis and blood panels are administered on-site.
First violation: 5-year ban. Second violation: lifetime ban. Zero exceptions, zero appeals outside protocol.
We follow the World Anti-Doping Agency's annual prohibited substances list in its entirety.
Our certification program allows athletes who maintain a clean record over 2+ seasons to carry the NBFB Certified Natural badge — recognized across our partner federations.
Testing is conducted by accredited independent laboratories. Results are confidential but violations are publicly disclosed.
Our roster of national champions will be published here after the inaugural 2026 NBFB Bulgarian Open. Athlete profiles, divisions, and competition highlights will follow as the season unfolds.
Every competitor at the 2026 NBFB Bulgarian Open will undergo a mandatory polygraph examination before stepping on stage, in addition to urine and blood testing conducted by WADA. Combining a pre-competition polygraph with WADA-administered biological testing sets a new standard for natural sport in Bulgaria and reinforces our commitment to a genuinely drug-free stage.
Full scorecards, placings, and photos from the 2026 NBFB Bulgarian Open will be published here after the event.
