According to Men's Health, a physically fit adult man should be able to bench-press his own body weight one time; as a general rule, youth fitness tests do not include weight-lifting exercises.
The American College of Sports Medicine encourages children and adolescents to engage in strength training. However, it warns that strength training for these age groups is not about lifting maximal amounts of weight or trying to build large muscles. Instead, it should be part of a complete program of fitness training intended to help the musculoskeletal system develop. Strength training with heavy weights should be avoided to reduce the risk of injuries to growth plates.
