In professional bodybuilding, competitors appear in lineups and perform specified poses (and later individual posing routines) for a panel of judges who rank them based on symmetry, muscularity, size, conditioning, posing, and stage presentation.

At the time of shooting ''Pumping Iron'', Schwarzenegger (while never admitting to steroid use until long after his retirement) said that "you have to do anything you can to get the advantage in competition". He would later say that he does not regret using anything. To combat anabolic steroid use and in the hopes of becoming a member of the IOC, the IFBB introduced doping tests for both steroids and other banned substances. Although doping tests occurred, the majority of professional bodybuilders still used anabolic steroids for competition. During the 1970s, the use of anabolic steroids was openly discussed, partly due to the fact they were legal. In the Anabolic Steroid Control Act of 1990, U.S. Congress placed anabolic steroids into Schedule III of the

Professional bodybuilding

In the modern bodybuilding industry, the term "
professional A professional is a member of a profession or any person who works in a specified professional activity. The term also describes the standards of education and training that prepare members of the profession with the particular knowledge and sk ...
" generally means a bodybuilder who has won qualifying competitions as an amateur and has earned a "pro card" from their respective organization. Professionals earn the right to compete in competitions that include monetary prizes. A pro card also prohibits the athlete from competing in federations other than the one from which they have received the pro card. Depending on the level of success, these bodybuilders may receive monetary compensation from sponsors, much like athletes in other sports.


Natural bodybuilding

Due to the growing concerns of the high cost, health consequences, and illegal nature of some steroids, many organizations have formed in response and have deemed themselves "natural" bodybuilding competitions. In addition to the concerns noted, many promoters of bodybuilding have sought to shed the "freakish" perception that the general public has of bodybuilding and have successfully introduced a more mainstream audience to the sport of bodybuilding by including competitors whose physiques appear much more attainable and realistic. In natural contests, the testing protocol ranges among organizations from

. Penalties also range from organization to organization from suspensions to strict bans from competition. It is also important to note that natural organizations also have their own list of banned substances and it is important to refer to each organization's website for more information about which substances are banned from competition. There are many natural bodybuilding organizations; some of the larger ones include: MuscleMania, Ultimate Fitness Events (UFE), INBF/WNBF, and INBA/PNBA. These organizations either have an American or worldwide presence and are not limited to the country in which they are headquartered.


Men's physique

Due to those who found open-bodybuilding to be "too big" or "ugly" and unhealthy, a new category was started in 2013. The first Men's Physique Olympia winner was Mark Wingson, who was followed by Jeremy Buendia for four consecutive years. Like open-bodybuilding, the federations in which bodybuilders can compete are natural divisions as well as normal ones. The main difference between the two is that men's physique competitors pose in board shorts rather than a traditional posing suit and open-bodybuilders are much larger and are more muscular than the men's physique competitors. Open-bodybuilders have an extensive routine for posing while the Physique category is primarily judged by the front and back poses. Many of the men's physique competitors are not above 200 lbs and have a bit of a more attainable and aesthetic physique in comparison to open-bodybuilders. Although this category started off slowly, it has grown tremendously, and currently men's physique seems to be a more popular class than open-bodybuilding.


Classic physique

Preparations


Bulking and cutting

The general strategy adopted by most present-day competitive bodybuilders is to make muscle gains for most of the year (known as the "off-season") and, approximately 12–14 weeks from competition, lose a maximum of body fat (referred to as "cutting") while preserving as much muscular mass as possible. The bulking phase entails remaining in a net positive energy balance (

surplus). The amount of a surplus in which a person remains is based on the person's goals, as a bigger surplus and longer bulking phase will create more fat tissue. The surplus of calories relative to one's energy balance will ensure that muscles remain in a state of

fat while preserving as much muscle as possible. The larger the calorie deficit, the faster one will lose weight. However, a large calorie deficit will also create the risk of losing muscle tissue. The bulking and cutting strategy is effective because there is a well-established link between muscle hypertrophy and being in a state of positive energy balance. A sustained period of caloric surplus will allow the athlete to gain more fat-free mass than they could otherwise gain under eucaloric conditions. Some gain in fat mass is expected, which athletes seek to oxidize in a cutting period while maintaining as much lean mass as possible.


Clean bulking

The attempt to increase muscle mass in one's body without any gain in fat is called clean bulking. Competitive bodybuilders focus their efforts to achieve a peak appearance during a brief "competition season". Clean bulking takes longer and is a more refined approach to achieving the body fat and muscle mass percentage a person is looking for. A common tactic for keeping fat low and muscle mass high is to have higher calorie and lower calorie days to maintain a balance between gain and loss. Many clean bulk diets start off with a moderate amount of carbs, moderate amount of protein, and a low amount of fats. To maintain a clean bulk, it is important to reach calorie goals every day.

goals (carbs, fats, and proteins) will be different for each person, but it is ideal to get as close as possible.

hypertrophy Hypertrophy is the increase in the volume of an organ or tissue due to the enlargement of its component cells. It is distinguished from hyperplasia, in which the cells remain approximately the same size but increase in number.Updated by Linda J. ...
: sarcoplasmic and myofibrillar. Sarcoplasmic hypertrophy leads to larger muscles and so is favored by bodybuilders more than myofibrillar hypertrophy, which builds athletic strength. Sarcoplasmic hypertrophy is triggered by increasing repetitions, whereas myofibrillar hypertrophy is triggered by lifting heavier weight. In either case, there is an increase in both size and strength of the muscles (compared to what happens if that same individual does not lift weights at all), however, the emphasis is different.


Nutrition

The high levels of muscle growth and repair achieved by bodybuilders require a specialized diet. Generally speaking, bodybuilders require more

This is a widely debated topic, with many arguing that 1 gram of protein per pound of body weight per day is ideal, some suggesting that less is sufficient, while others recommending 1.5, 2, or more. It is believed that protein needs to be consumed frequently throughout the day, especially during/after a workout, and before sleep.

Whey is the type of protein contained in many popular brands of protein supplements and is preferred by many bodybuilders because of its high biological value (BV) and quick absorption rates.

Meals

Some bodybuilders often split their food intake into 5 to 7 meals of equal nutritional content and eat at regular intervals (e.g., every 2 to 3 hours). This approach serves two purposes: to limit overindulging in the cutting phase, and to allow for the consumption of large volumes of food during the bulking phase. Eating more frequently does not increase

Dietary supplements

The important role of nutrition in building muscle and losing fat means bodybuilders may consume a wide variety of

Injecting oil into muscles

A recent trend in bodybuilding is to inject synthol into muscles to create larger bulges, or injecting

Site enhancement oil, often called ''santol'' or ''synthol'' (no relation to the Synthol mouthwash brand), refers to oils injected into muscles to increase the size or change the shape. Some bodybuilders, particularly at the professional level, inject their muscles with such mixtures to mimic the appearance of developed muscle where it may otherwise be disproportionate or lacking. This is known as "fluffing". Synthol is 85% oil, 7.5%

Rest

Although muscle ''stimulation'' occurs when lifting weights, muscle ''growth'' occurs afterward during rest periods. Without adequate rest (48 to 72 hours) and sleep (6 to 8 hours a night), muscles do not have an opportunity to recover and grow. Additionally, many athletes find that a daytime nap further increases their body's ability to recover from training and build muscles. Some bodybuilders add a

Overtraining

Overtraining occurs when a bodybuilder has trained to the point where their workload exceeds their recovery capacity. There are many reasons why overtraining occurs, including lack of adequate nutrition, lack of recovery time between workouts, insufficient sleep, and training at a high intensity for too long (a lack of splitting apart workouts). Training at a high intensity too frequently also stimulates the
