One way to gauge how hard you’re working during these intervals is through the scale of perceived exertion, where a 1 means no effort and a 10 means maximal effort. You’ll definitely be breathing hard during the work intervals (of course, slow it down or take a break if you start to feel a little too breathless), and you’ll be able to take full advantage of the rest periods. Because it’s a cardio workout, expect to increase your heart rate. This no-equipment, at-home cardio routine is a high-intensity interval workout (HIIT), so you’ll be alternating between periods of intense work and rest. It’s actually pretty simple to get in a great, no-equipment cardio workout at home: The best way to do it, as we reported previously, is to choose exercises that are compound movements (meaning they work multiple muscle groups at a time, like squats or push-ups) and dial up the intensity: Think exercises with lots of movement that you can rep out quickly. But with gyms and studios closed due to the coronavirus-and some neighborhoods a little too crowded for exercising outdoors safely- at-home cardio routines have become the new normal for a sweaty workout. Getting in a no-equipment cardio workout at home might seem like a challenge for those of us used to indoor cycling classes or runs either outside or on the treadmill.
