In a wave of new research and expert consensus, VO2 max has taken center stage as arguably the most crucial health and fitness metric for people of all ages, overtaking traditional indicators such as BMI or body weight. This push to recognize VO2 max’s importance underscores its powerful ability to predict cardiovascular health, longevity, and even cognitive function, prompting a growing number of doctors and fitness professionals to urge everyone—from elite athletes to ordinary individuals in Thailand—to pay attention to and improve their VO2 max. But with so much attention now on this number, what exactly is VO2 max, why does it matter, and how can Thais take actionable steps to improve it?

A fresh perspective on exercise is shaking up how we approach physical wellbeing, with new recommendations from Harvard Health Publishing advocating a “three-pronged” strategy for optimal fitness. This approach, derived from years of research and now the subject of renewed attention in 2025, consists of combining moderate-intensity aerobic exercise, vigorous-intensity aerobic bursts, and regular strength training—a formula that promises to boost cardiovascular health, maintain muscle strength, and promote longevity (Harvard Health).
