A common way to assess cardiovascular fitness at home is by performing a simple step test. This involves stepping up and down on a platform or staircase at a steady pace for a predetermined duration, usually around three to five minutes. After completing the test, individuals measure their heart rate immediately post-exercise and after a recovery period. The quicker the heart rate returns to baseline, the better the cardiovascular fitness level. This method is accessible and effective for those wanting to monitor their fitness without complex equipment or facilities.
