Six in the morning, the gym nearly empty, a lifter on her twelfth week of prep writing the day’s weights in a notebook. A Saturday prejudging in a hotel ballroom, forty competitors backstage with tan touch-ups and resistance bands, a head judge calling “quarter turn to the right”. A packed arena in Las Vegas in late September, where Nick Walker won the 2026 Mr. Olympia. Bodybuilding is a sport judged on how a body looks on one day under stage lights, and the work behind that day takes months or years in the gym and the kitchen.

This page covers bodybuilding and the physique sports that grew out of it: Men’s Physique, Classic Physique, Bikini, Figure, Wellness, Women’s Physique, and the natural, drug-tested federations. It explains how a show works, how athletes move from a local contest to a pro card, and most of all bodybuilding health: what the research says about steroids, diuretics and extreme dehydration, body image, and how to compete and still be healthy the week after the show.

Bodybuilding at a glance

What it is	A judged physique sport. Athletes are scored on how they look and present on stage, not on what they lift.
Judging (bodybuilding)	In the NPC’s words, the “total package, which is a balance of size, symmetry, and muscularity”, shown in eight mandatory poses and a posing routine of up to 60 seconds.
Main divisions	Men’s Bodybuilding (and 212 at pro level), Classic Physique, Men’s Physique, Women’s Bodybuilding, Women’s Physique, Figure, Bikini, Wellness and Fitness; plus teen, collegiate, masters and novice classes.
Biggest show	The Olympia (IFBB Pro League). The 2026 Olympia weekend ran September 24–27 in Las Vegas, the 62nd Mr. Olympia.
Tested vs untested	The NPC and IFBB Pro League mostly do not drug-test; natural federations such as the WNBF, OCB and INBA/PNBA test every competitor, and the Pro League runs separate “Natural” shows with testing.
Main health issues	Lifting injuries, long dieting and its effects on mood, hormones and sleep, eating and body-image problems, and the serious risks of anabolic steroids, diuretics and dehydration.

How a bodybuilding show works

Most amateur shows run in two parts. Prejudging, usually in the morning, is where the scoring happens: in the NPC’s rules the judging round counts for 100% of the score, and the evening finals are scored only if a confirmation round is needed. In prejudging, competitors come out in a group, then in small “call-outs” so judges can compare them side by side. The evening show is the part friends and family come to see: individual posing routines to music, awards and, for the top finishers, a posedown.

Each division shows the body in its own way. Men’s Bodybuilding uses eight mandatory 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, including a “favorite classic pose” and no most muscular, and sets a weight limit for each height class. Men’s Physique, Bikini, Figure and Wellness are judged mostly in front, side and back stances or quarter turns. Our bodybuilding rules page goes division by division, with the judging words from the rulebooks, attire rules and the differences between tested and untested federations.

The divisions in plain words

• Men’s Bodybuilding: the most muscle, with symmetry and conditioning. Weight classes from bantamweight to super-heavyweight at NPC shows; at pro level, the Open and the 212 (for athletes 212 lb and under).
• Classic Physique: the “golden era” look: a smaller waist, flowing lines and a body-weight cap set by height (the NPC table runs from 167 lb for athletes up to 5’4″ to 274 lb over 6’7″). Competitors wear black trunks.
• Men’s Physique: board shorts, quarter turns, shape and condition. The NPC’s rules say outright that “this is not a bodybuilding contest so extreme muscularity should be marked down.”
• Bikini: a foundation of muscle that shapes the body, round glutes, a conditioned core and overall presentation, with a model walk. No striations, no figure-level density.
• Figure: more muscle and a V-taper, with “small amount of muscle separation” and no visible striations; judged in quarter turns.
• Wellness: a fuller lower body (glutes and thighs) with a fit, athletic upper body.
• Women’s Physique and Women’s Bodybuilding: the most muscular women’s divisions, with mandatory poses done with open hands in Women’s Physique.

Bodybuilding at every level

Teens

Lifting weights is great for teenagers when it’s supervised and built on good technique, and the American Academy of Pediatrics (AAP) supports it. Competing on a bodybuilding stage is a different question. The NPC requires competitors in its teen divisions to be at least 18 and not over 19 on the day of the show, and its 2026 Teen, Collegiate and Masters Nationals ran July 15–18 in Pittsburgh. Some natural federations run teen classes too, with their own age limits. Our youth bodybuilding page covers what pediatricians say, healthy goals for teens and the questions parents ask.

First-time and amateur competitors

Most competitors are amateurs with jobs and families who do one or two shows a year. Many start in a novice class at a local show. In the United States, the NPC is the largest amateur organization and the only amateur route to an IFBB Pro League card. Natural athletes have their own path through the WNBF, OCB, INBA/PNBA and other tested federations, which award their own pro cards. Our leagues and associations page explains who runs what.

Pros and the Olympia

The Olympia is the IFBB Pro League’s world championship. The 2026 Olympia weekend ran September 24–27 in Las Vegas, with finals at the Orleans Arena. Nick Walker won his first Mr. Olympia title, ahead of Samson Dauda and Derek Lunsford; Niall Darwen won Classic Physique, Keone Pearson the 212 and Ryan Terry Men’s Physique. Natural bodybuilding has its own showcase: the INBA/PNBA has held a Natural Olympia since 1998.

Masters athletes

Bodybuilding is one of the few sports where people step on stage for the first time in their 40s, 50s or later. NPC national masters classes run from 35+ to 80+. Older athletes often need longer to recover between hard sessions, and a check-up before a long diet is a good idea at any age, especially for anyone with a heart condition, high blood pressure or diabetes.

Bodybuilding health: what every competitor should know

Bodybuilding health is the heart of this section. Training hard and dieting carefully can be done safely, and many people get fitter and healthier along the way. The serious risks in the sport come mostly from drugs and from extreme measures in the last days before a show. This section is general information, not medical advice.

Anabolic steroids: the honest picture

Steroid use is an open secret in untested bodybuilding, and social media often makes it look routine. The medical picture is clear. The National Institute on Drug Abuse (NIDA) lists high blood pressure, heart attacks and strokes, “even in athletes younger than 30”, among the risks of misusing anabolic steroids, as well as aggression, mania and major depression; about 32% of people who misuse them become dependent. In men, it lists shrinking testicles, decreased sperm production and enlarged breasts; in women, a deeper voice and body-hair growth that can become permanent. An Endocrine Society scientific statement linked performance-enhancing drug use to an increased risk of death and to heart, psychiatric, liver, kidney and hormonal problems, and noted that most users aren’t competitive athletes at all but recreational lifters.

The deaths of well-known bodybuilders make headlines, and research is starting to measure the risk. A 2025 study in the European Heart Journal followed 20,286 male athletes who competed in IFBB-affiliated shows between 2005 and 2020. It found 121 deaths, 46 classified as sudden cardiac deaths; among athletes still competing, the rate was about 33 per 100,000 athlete-years, and professionals had about five times the risk of amateurs. Autopsies of sudden cardiac deaths consistently showed enlarged hearts. The study didn’t measure drug use directly, and other researchers note that many factors are mixed together, but the authors called on the sport and doctors to improve prevention. If you have used or are using steroids, a doctor can check your heart, blood pressure, blood tests and mental health without judgment; stopping suddenly can bring on depression, so get medical help to stop.

Diuretics and dehydration before a show

“Peak week”, the final days before a show, is where some of the most dangerous practices happen: cutting water, manipulating sodium and taking diuretics (“water pills”) to look harder on stage. Diuretics are prescription medicines, and Cleveland Clinic lists unbalanced electrolytes, low potassium, dehydration, dizziness, heart palpitations and muscle cramps among their risks. They’re banned at all times under the World Anti-Doping Agency’s Prohibited List, and the IFBB Pro League’s natural shows test for them. A widely cited review of natural contest preparation concluded that dehydration and electrolyte manipulation in the final days and hours “can be dangerous, and may not improve appearance”. We don’t publish peak-week protocols. If you feel faint, confused, have a racing or irregular heartbeat or severe cramps before or after a show, stop and get medical help; call 911 for collapse or chest pain.

Dieting, body image and the week after the show

Getting stage-lean means months of eating less while training hard. The same review recommends losing about 0.5 to 1% of body weight per week to keep as much muscle as possible, and warns that physique athletes are at higher risk of eating and body-image disorders, so they should have access to mental-health professionals. A 2026 study of 60 competitive bodybuilders found reduced libido, hunger, sleep problems and frequent binge eating after shows in both men and women, and menstrual changes in many women. Muscle dysmorphia (sometimes called “bigorexia”), a constant feeling of being too small, is a recognized body-image disorder. If food, the mirror or the scale is taking over your life, or your period has stopped, talk to a doctor, a sports dietitian or a mental-health professional.

Tanning and skin

Stage lights wash out pale skin, so competitors use a competition tan. Most are sunless tanners built on DHA (dihydroxyacetone). The FDA allows DHA for external use only, not on the lips, mucous membranes or the eye area, and suggests asking a spray-tan booth how it protects your eyes, lips and lungs. Skip the tanning bed: the American Academy of Dermatology says indoor tanning can more than double the risk of melanoma. And a sunless tan doesn’t protect you from the sun unless the label lists an SPF.

When to see a doctor, physical therapist or athletic trainer

Get a check-up before your first prep, especially if you’re over 35 or have a heart condition, high blood pressure or diabetes. See a sports medicine doctor or physical therapist for joint pain that lasts more than a few days, a sudden pop or sharp pain during a lift (pec and biceps tears happen in heavy pressing and pulling), back pain that runs down a leg, or numbness. Get urgent care for chest pain, fainting, a racing heartbeat, or dark, cola-colored urine after a hard session. Our bodybuilding injuries page covers the common lifting injuries in detail.

Training for bodybuilding

Bodybuilding training is resistance training aimed at building muscle: compound lifts like squats, presses and rows, plus isolation work for each muscle group, with enough volume and enough recovery. Good technique comes before heavy weights, and progress comes over years, not weeks. A coach who has prepared natural athletes, or a qualified personal trainer, can save you a lot of trial and error. Our bodybuilding training page covers off-season and prep training, cardio and posing practice. Many lifters track sleep and readiness with a wearable; see HRV for athletes.

Nutrition is half the sport. The natural contest-prep review suggests most athletes do well on 2.3–3.1 g of protein per kg of lean body mass per day during a diet, 15–30% of calories from fat, and the rest from carbohydrate; individual needs differ, so a sports dietitian is worth it. Creatine monohydrate and caffeine are among the few supplements with good evidence, and anyone in a tested federation should pick products certified for sport. See bodybuilding nutrition and supplements, our creatine and protein powder guides, and the show day page for what to pack on the day.

Recovery for bodybuilders

Muscle grows between sessions. The CDC, citing the American Academy of Sleep Medicine, recommends 8–10 hours of sleep a night for teens and 7 or more for adults, and sleep often suffers late in a diet. Plan easier weeks, eat enough protein through the day, and treat foam rollers, massage guns and recovery shoes as comfort tools, not treatment. One thing to know if you love ice baths: a 2015 study found that regular cold-water immersion right after strength training reduced long-term gains in strength and muscle, so many lifters keep cold plunges away from lifting days. After a show, a gradual return to normal eating and a few easier weeks help body and mind; our bodybuilding recovery page covers the reverse diet and post-show weeks.

Gear for bodybuilding

You don’t need much: a good gym, a notebook or app, and shoes with a stable sole. A belt for heavy squats and deadlifts and straps for heavy pulls are the two accessories most lifters end up buying. The Gymreapers Quick Locking Belt (about $35, 4-inch neoprene) and Gymreapers lifting straps (about $15, padded, 18-inch cotton) are popular, inexpensive picks; Thorne Creatine (about $44, NSF Certified for Sport) suits tested athletes; and a TriggerPoint GRID foam roller (about $40) lives in many gym bags. Our bodybuilding gear guide adds bags, posing wear, competition tans and recovery tools, and best wearables for bodybuilders covers trackers.

Bodybuilding FAQs

Is bodybuilding healthy?

Resistance training and good nutrition are healthy for almost everyone. The health risks in competitive bodybuilding come mainly from anabolic steroids and other drugs, diuretics and extreme dehydration before shows, and long, hard diets that can affect mood, hormones and eating habits. Competing natural, dieting gradually and getting regular check-ups keep most of the benefits and avoid most of the risks.

What’s the difference between natural and untested bodybuilding?

Natural federations such as the WNBF, OCB and INBA/PNBA test competitors for banned substances, using polygraphs, urine tests or both, and follow the World Anti-Doping Agency’s list. The NPC and IFBB Pro League generally don’t test, except at their separate “Natural” shows. If you want to compete without drugs, choose a tested federation.

How do I get started in bodybuilding competitions?

Train consistently for a while first, pick a federation and a division that fits your physique, and choose a local show far enough away to diet gradually. Many first-timers enter a novice class. Learn and practice the division’s poses for weeks, not days, and get a check-up before your prep.

Which division should I compete in?

It depends on your build and what you enjoy. Men with a lot of muscle tend toward Bodybuilding or Classic Physique; leaner, athletic men toward Men’s Physique. Women choose among Bikini, Wellness, Figure, Women’s Physique and Women’s Bodybuilding, roughly from least to most muscle. Watching a local show and talking to the judges afterward helps.

Who won the 2026 Mr. Olympia?

Nick Walker won his first Mr. Olympia title at the 2026 Olympia in Las Vegas (September 24–27), ahead of Samson Dauda and Derek Lunsford. Niall Darwen won Classic Physique and Ryan Terry won Men’s Physique.

Do I need a competition tan?

Almost everyone uses one, because stage lights wash out muscle detail. Federations ask for a natural-looking tone; the NPC bans orange, yellow, red, green, gold or metallic finishes. Use sunless tanning products, not tanning beds, and keep DHA away from your eyes and lips.

Bodybuilding at its best is a long project: years of training, learning how your body responds, and standing on stage proud of the work.
