Purpose of the Interactive VO₂ Max Decline Tool:

This tool serves as a visual representation of the decline in VO₂ max, a critical marker of your cardiorespiratory fitness, as you age. VO₂ max is one of the strongest predictors of longevity and overall health. By entering your current age and selecting an activity you can comfortably perform today, you’ll see where you stand in relation to optimal fitness levels. More importantly, you can project where you want to be in your later decades by choosing a target age and an activity you aspire to maintain. The goal here is to provide a clear, data-driven perspective on how maintaining—or even improving—your VO₂ max can significantly enhance both your lifespan and healthspan, empowering you to make informed decisions today that pay dividends tomorrow.
