Bodybuilding is the practice of increasing the size of your muscles through intensive exercise. It generally uses a variety of bodybuilding exercises that target a specific muscle group. Several organizations in the United States offer bodybuilding competitions at the national level. Joining a bodybuilding club is a common way to get involved in these competitions.
The major muscle groups targeted by bodybuilding exercises include the chest, shoulder and back muscles for the upper body. The main muscles in the arms are the biceps and triceps, and the primary leg muscles are the quadriceps and hamstrings. The abdominal muscles are the major muscle group for the trunk of the body.

Exercises that use a large amount of weight with a low number of repetitions build strength, while exercises that use a low amount of weight and a high number of repetitions build endurance. Bodybuilding exercises generally fit in the middle of these two extremes. Most exercise sets in bodybuilding consist of 8 to 12 repetitions.
The rest period between sets is also an important consideration for bodybuilding exercises. The ideal rest period between sets is usually about one minute. Larger muscle groups use more oxygen and require more rest, while muscle groups with good blood supplies benefit from a shorter rest period.
