The head judge says “Competitors, quarter turn to the right”, and twelve people turn at once under the lights, holding their stomachs tight and trying to keep their legs from shaking. Five judges at a table write numbers on their sheets. That moment, repeated over call-outs and comparisons, is how a bodybuilding show is decided. This page explains the bodybuilding rules that matter: how judging works, the mandatory poses and criteria for each division, what you can wear, tanning rules, and the big difference between natural (drug-tested) and untested federations. We use the National Physique Committee (NPC) rulebook pages as the reference, since the NPC is the largest amateur federation in the US; other federations are similar but check your own show’s rules.

How bodybuilding judging works

At NPC shows, men’s bodybuilding is scored in two rounds. The judging round (prejudging) counts for 100% of the score; the finals are scored only if a confirmation round is needed. In prejudging, each competitor walks to center stage alone and runs through the mandatory poses, then the group lines up and the head judge calls small groups to the middle (“call-outs”) for side-by-side comparisons. Being called in the first call-out, and toward the center, usually means the judges have you near the top.

In bodybuilding, the NPC tells judges to score the “total package, which is a balance of size, symmetry, and muscularity”. For the women’s divisions, the NPC lists four criteria: muscularity and condition (both of which vary by division), symmetry and balance, and presentation (posing). Gymnastic moves are not allowed in Men’s Physique, and the NPC bans lewd poses.

Mandatory poses and criteria by division

Division	What judges look for	Poses	Attire
Men’s Bodybuilding	Size, symmetry and muscularity (“total package”)	8 mandatory poses; 60-second posing routine in finals	Solid-color cloth trunks, at least half rear coverage, barefoot
Classic Physique	Same “total package” wording, within a weight limit by height	5 mandatory poses incl. favorite classic pose (no most muscular); 60-second routine	Black cloth trunks, barefoot
Men’s Physique	Shape, symmetry, muscularity and overall condition; “extreme muscularity should be marked down”	Quarter turns; stage presence	Board shorts, shirtless, barefoot
Women’s Physique	More muscular density than Figure, clear separation; not overly striated	5 mandatory poses with open hands; 60-second routine	Two-piece suit, barefoot
Figure	Overall balance of muscle, “small amount of muscle separation”, no visible striations	Quarter turns only, no routine	Two-piece suit, high heels
Wellness	More mass in hips, glutes and thighs; developed upper body	Front stance, quarter turns, model walk	Two-piece suit, heels
Bikini	A foundation of muscle that shapes the body; no figure-level density or striations	Front and back stance, model walk	Two-piece suit, high heels

Men’s Bodybuilding (and 212)

The eight mandatory poses are front double biceps, front lat spread, side chest, back double biceps, back lat spread, side triceps, abdominals and thighs, and most muscular. Each competitor has up to 60 seconds for the mandatory poses in judging and up to 60 seconds for the posing routine at finals. NPC shows split bodybuilding into weight classes from bantamweight to super-heavyweight. Trunks must be a solid, non-distracting color, with no metallic or shiny material and no padding, and competitors can’t wear watches, chains or other jewelry. At pro level, the IFBB Pro League also runs the 212 division, for competitors who weigh 212 lb (96 kg) or less, with the same poses as the Open.

Classic Physique

Five mandatory poses: front double biceps, side chest, back double biceps, abdominals and thighs, and a favorite classic pose, with no most muscular. Each competitor gets up to 60 seconds. Classic Physique has a maximum body weight for each height class, from 167 lb for competitors up to 5’4″ to 274 lb for those over 6’7″, and shows run two to four height classes depending on size. Competitors wear black cloth trunks and nothing on the chest or torso.

Men’s Physique

Each competitor walks to center stage alone and does quarter turns, with an optional hand on the hip or in a pocket, then the group returns for comparisons in quarter turns. Board shorts start an inch below the navel and end two inches above the kneecap; no spandex, and no logos except the maker’s. The NPC says judges look for “fit contestants who display proper shape and symmetry combined with muscularity and overall condition”, plus stage presence.

Bikini, Wellness and Figure

Bikini athletes do a front stance, a turn to a back stance and a model walk; the NPC wants “full round glutes with a slight separation between the hamstring and glute area”, a little roundness in the shoulders, a conditioned core, and an overall look including hair, makeup, suit and tan, but no striations. Wellness is for athletes with “more body mass in the hips, glutes and thighs”, with conditioning close to Bikini and slightly more muscle. Figure competitors do four quarter turns and are judged on an overall balance of muscular development with a V-shape, some separation and no striations. All three wear two-piece suits with V-shaped bottoms (no thongs) and high heels.

Women’s Physique and Women’s Bodybuilding

Women’s Physique uses five mandatory poses done with open hands: front double biceps, back double biceps, side triceps with one leg extended, side chest with both arms extended, and abdominals and thighs, in up to 30 seconds, plus a 60-second routine at finals. The NPC wants “full muscle bellies” and clear separation, but not the “graininess associated with female bodybuilding”. Women’s Bodybuilding, the most muscular women’s division, is judged on bodybuilding poses; the pro title is Ms. Olympia.

Tanning and oil rules

Every NPC division says the same thing: tanning products must give a natural tone. Products that make the skin orange, yellow, red, green, gold or metallic are not allowed, and so is excessive oil, moisturizer or cream. Bikini, Figure and Wellness athletes can’t use posing oil but can use a light “glaze”. Many shows have an official spray-tan company on site. For your skin: the FDA allows DHA, the active ingredient in sunless tanners, for external use only, not on the lips or around the eyes, so ask the tanner how they protect your eyes, lips and lungs. Skip tanning beds; the American Academy of Dermatology says indoor tanning can more than double the risk of melanoma.

Natural vs untested federations: the drug-testing rules

This is the biggest rule difference in the sport, and it shapes what a division looks like at the top level.

• NPC and IFBB Pro League (untested): regular shows don’t drug-test. The Pro League runs separate “Natural” pro shows (the Ben Weider Natural Pro among them) with polygraph and urine tests, mandatory testing for anabolic agents and diuretics, and the top two in each division tested by urinalysis. Penalties run from a one-year suspension to a lifetime ban for a third offense. Some NPC amateur shows are also run as “Natural” tested events.
• WNBF: every competitor must pass a polygraph with a WNBF-approved examiner, and winners of pro-qualifying classes are urine-tested to the World Anti-Doping Agency (WADA) Code. Athletes must be free of anabolic steroids, growth hormone and peptides for 10 years. Since 2022, a failed test for steroids, growth hormone, peptides or SARMs brings a lifetime ban.
• OCB: polygraph screening for every competitor, with urine tests for pro-qualifying winners and random tests at the promoter’s discretion. The OCB explains that polygraphs are used because many steroids stop showing up in urine within weeks and growth hormone isn’t caught by routine urine tests.
• INBA/PNBA: urine or blood tests at WADA-accredited labs, random testing at events and out of competition, with bans from one year to life.
• IFBB (the international amateur federation): a separate organization from the IFBB Pro League. It has been a signatory to the World Anti-Doping Code since 2003.

Two practical rules for tested athletes. First, prescription medicines on WADA’s list (including diuretics) can still be used with a therapeutic use exemption; the OCB, for example, wants the form at least 10 days before the show. Second, supplements can be contaminated, so pick products certified for sport, such as NSF Certified for Sport. Our bodybuilding nutrition and supplements page has more on that. For the organizations themselves, see bodybuilding leagues and associations.

Age, class and safety rules

NPC teen divisions are for competitors who are at least 18 and not over 19 on the day of the show; collegiate classes are for students taking college courses that year who are 25 or under; masters classes start at 35+. Bring proof of age to national shows. Natural federations set their own teen ages, so check before you enter; our youth bodybuilding page has more. No rule stops anyone from cutting water or using diuretics before an untested show, but medical sources are clear that these practices are dangerous; see the health section of our bodybuilding hub and the show day page for what to do on the day.

What to bring to stay within the rules

A legal suit or trunks (bring a spare), heels if your division needs them, a competition tan that gives a natural tone, and a bag big enough for food, water and touch-up gear. The Pro Tan Competition Tanning Kit (about $50) is a single-show do-it-yourself kit with an exfoliator, overnight base coat, instant top coat and a small bottle of posing oil, all in carry-on sizes; the Under Armour Undeniable 5.0 Duffle (about $34) has a vented pocket for shoes and a water-resistant finish.

Bodybuilding rules FAQs

What are the 8 mandatory bodybuilding poses?

Front double biceps, front lat spread, side chest, back double biceps, back lat spread, side triceps, abdominals and thighs, and most muscular. Classic Physique uses five (with a favorite classic pose instead of most muscular), and Women’s Physique uses five with open hands.

How is bodybuilding scored?

Judges place competitors by comparing them in call-outs during prejudging. At NPC shows that round counts for 100% of the score; finals are only scored if a confirmation round is needed. Judges look at size, symmetry and muscularity in bodybuilding, and division-specific criteria elsewhere.

What’s the weight limit in Classic Physique?

It depends on height. The NPC table runs from 167 lb for competitors up to 5’4″ to 274 lb for those over 6’7″. The IFBB Pro League’s 212 division is a separate bodybuilding class for athletes 212 lb or lighter.

Are NPC shows drug tested?

Most are not. Some NPC shows and some IFBB Pro League shows are run as “Natural” events with polygraph and urine tests. Federations such as the WNBF, OCB and INBA/PNBA test every show.

Can I wear heels or jewelry on stage?

Bikini, Figure and Wellness competitors wear high heels and may wear jewelry. Men’s divisions and Women’s Physique compete barefoot, and men can’t wear watches, chains or other jewelry during judging.
