To lower your True Age, you'll need to improve your cardiorespiratory fitness. You can do this by getting your heart pumping and keeping it pumping for a period of time. Aim to do enough activity to reach 100 PAI in a 7-day period.
Your True Age is determined by several factors, including your heart rate data, which you can measure and track on your wearable. So, after several weeks of being more active-- whether you've been gardening, chasing after kids or taking an extra workout class, use the True Age Calculator again to see how much you've improved your result.
