VO₂ max is essentially a measure of how efficiently your body delivers and uses oxygen during exercise — involving your heart, lungs, blood flow, and muscles all working together.
As we age, VO₂ max naturally declines (about 5–10% per decade after 30 if we’re inactive), which can show up as lower energy, reduced endurance, and feeling more easily fatigued.
The encouraging part?
This is one of the most trainable markers of health.
With the right kind of movement — especially a mix of steady effort and short higher-intensity bursts — you can improve your VO₂ max at any age and support both your daily energy and long-term heart health.
