Body composition is commonly measured by methods such as bioelectrical impedance analysis, dual-energy X-ray absorptiometry (DEXA), and skinfold measurements. These techniques assess the proportion of lean mass versus fat mass in the body, providing insight into overall health and fitness levels. Understanding body composition is essential for evaluating fitness progress, designing effective exercise programs, and identifying potential health risks associated with excessive body fat or low muscle mass. Maintaining a healthy body composition can improve physical performance and reduce health complications.
