Mowing the lawn and sweeping the floors are great, but are they as good as getting that heartbeat up? Several studies say cardiorespiratory fitness is a greater indicator for mortality prevention. In the past there have been studies showing the better performance in the maximal treadmill test the better lower the chances of cardiovascular mortality. Now in a large study, they are showing the maximal treadmill test is a better predictor than leisure physical activity for all causes or mortality. So, get out enjoy the day, and get that heartbeat up.
