A form of exercise and competitive sport in which the primary aim of participants is to develop muscularity and body mass, and to produce symmetry and harmony between different body parts. In addition, body-builders try to achieve definition so that muscles can be separated from each other. During competition, body-builders are judged while posing in specific body positions. Weight-training for body-building usually incorporates ‘split’ systems (a few selected muscles or muscle groups are exercised in each session), which have a low risk of serious injury. The training does not improve maximal aerobic power or endurance capacity, but it does seem to have some health-promoting effects (for example, steroid-free male and female body-builders tend to have favourable lipoprotein-lipid profiles, reducing the risk of coronary heart disease). Well-trained body-builders are characterized by having lean and muscular bodies with enhanced muscular strength and power.
