Common types of fitness assessments include body composition, flexibility tests, cardiovascular fitness evaluations, and muscular strength assessments. Body composition tests measure the proportion of fat to lean mass, often using methods like BMI, skinfold calipers, or bioelectrical impedance. Flexibility can be evaluated using the sit-and-reach test, while cardiovascular fitness can be assessed through a treadmill test or the Cooper test. Muscular strength is typically measured through one-rep max tests for various exercises. These assessments help track progress, identify fitness levels, and guide personalized training programs.
