For good health, the most comprehensive measurement of physical fitness from the options provided is VO2 max. VO2 max indicates the maximum amount of oxygen your body can utilize during intense exercise, which is a strong indicator of cardiovascular fitness and overall physical performance. It reflects your aerobic capacity and endurance, which are crucial for maintaining good health.
While Body Fat percentage, BMI, and Target fitness levels are important, VO2 max directly measures your fitness level and cardiovascular health.
