The **Body Composition Assessment** is a type of fitness evaluation that measures body composition, specifically the ratio of fat mass to lean mass in the body. Methods include BMI (Body Mass Index), skinfold calipers, bioelectrical impedance analysis, and dual-energy X-ray absorptiometry (DEXA). Understanding body composition is crucial for developing tailored fitness programs and monitoring progress over time. A healthy composition is linked to reduced risks of obesity-related diseases and is a better health indicator compared to weight alone.
