The maximum amount of oxygen your body can use during a workout.
VO2 Max is the ultimate score of your cardiovascular fitness. It tells us how well your heart and lungs can deliver oxygen to your active muscles. Think of it as your 'engine size'—the higher it is, the more energy and stamina you have for life's adventures.
This is one of the most powerful predictors of a long, independent life. Improving your VO2 Max through fun activities like hiking or cycling is like investing in a high-performance future.
