What if there was a single number that could predict your risk of heart disease, your ability to stay independent as you age, and even how long you're likely to live?

That number is VO₂ max, and despite sounding complicated, it may be one of the most important health metrics you've never paid attention to.... (so much so, I talk about it quite a lot!) In fact, research suggests that low cardiorespiratory fitness is as dangerous as many of the risk factors we're taught to fear, including smoking, diabetes and high blood pressure.

In this video, I explain what VO₂ max actually is, why it reflects the combined health of your heart, lungs, circulation and muscles, and why it has become one of the strongest predictors of long-term health and longevity.

We'll explore the science behind VO₂ max, what happens to it as we age, the exercise strategies shown to improve it, and why building a bigger aerobic engine today may be one of the best investments you can make in your future health.

What you'll learn:
-What VO₂ max actually measures
-Why it predicts health and longevity so well
-The link between fitness and risk of early death
-How VO₂ max changes as you get older
-Why HIIT is so effective for improving it
-The difference between interval training and steady cardio
-The risks of doing too much high-intensity exercise
-A practical weekly exercise plan for long-term health
