Primary care physicians who see young patients are often asked about strength training programs for children. Some parents are seeking ways to give their child a competitive edge in sports. Many parents of overweight children seek guidance about which activities are effective for weight loss. Musculoskeletal injuries and epiphyseal fractures are also a concern. Informed clinicians can reassure parents that, with adult supervision, proper equipment, and realistic expectations, strength training programs designed for children and adolescents are safe and effective.
