Bodybuilding is the practice of progressive resistance exercise to build, control, and develop one's muscles via hypertrophy. An individual who engages in this activity is referred to as a bodybuilder. It is primarily undertaken for aesthetic purposes over functional ones, distinguishing it from similar activities such as powerlifting and calisthenics.

In competitive bodybuilding, competitors appear onstage in line-ups and perform specified poses (and later individual posing routines) for a panel of judges who rank them based on conditioning, muscularity, posing, size, stage presentation, and symmetry. Bodybuilders prepare for competitions by exercising and eliminating non-essential body fat. This is enhanced at the final stage by a combination of carbohydrate loading and dehydration to achieve maximum muscle definition and vascularity. Most bodybuilders also tan and shave their bodies prior to competition.

Bodybuilding requires significant time and effort to reach the desired results. A novice bodybuilder may be able to gain 8–15 pounds (4–7 kg) of muscle per year if they lift weights for seven hours per week, but muscle gains begin to slow down after the first two years to about 5–15 pounds (2–7 kg) per year. After five years, gains can decrease to as little as 3–10 pounds (1–5 kg) per year. Some bodybuilders use anabolic steroids and other performance-enhancing drugs to build muscles and recover from injuries faster. However, using performance-enhancing drugs can have serious health risks. Furthermore, most competitions prohibit the use of these substances. Despite some calls for drug testing to be implemented, the National Physique Committee (considered the leading amateur bodybuilding federation) does not require testing.

The winner of the annual IFBB Mr. Olympia contest is recognized as the world's top male professional bodybuilder. Since 1950, the NABBA Universe Championships have been considered the top amateur bodybuilding contests, with notable winners including Ronnie Coleman, Jay Cutler, Steve Reeves, and Arnold Schwarzenegger.

Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It provides organisms with nutrients, which can be metabolized to create energy and chemical structures. Failure to obtain the required amount of nutrients causes malnutrition. Nutritional science is the study of nutrition, though it typically emphasizes human nutrition.

The type of organism determines what nutrients it needs and how it obtains them. Organisms obtain nutrients by consuming organic matter, consuming inorganic matter, absorbing light, or some combination of these. Some can produce nutrients internally by consuming basic elements, while some must consume other organisms to obtain pre-existing nutrients. All forms of life require carbon, energy, and water as well as various other molecules. Animals require complex nutrients such as carbohydrates, lipids, and proteins, obtaining them by consuming other organisms. Humans have developed agriculture and cooking to replace foraging and advance human nutrition. Plants acquire nutrients through the soil and the atmosphere. Fungi absorb nutrients around them by breaking them down and absorbing them through the mycelium.

A powder is a dry solid composed of many very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, although the terms powder and granular are sometimes used to distinguish separate classes of material. In particular, powders refer to those granular materials that have the finer grain sizes, and that therefore have a greater tendency to form clumps when flowing. Granulars refer to the coarser granular materials that do not tend to form clumps except when wet.
