If you are doing moderate-intensity physical activity, such as walking or hiking, you can talk, but not sing during the activity. Here are some examples of activities that require vigorous effort: If you’re being active at a vigorous level, you won’t be able to say more than a few words without pausing for a breath. You may use the Talk Test to gauge the intensity of your aerobic physical activity. Vigorous-intensity aerobic activity means you’re breathing hard and fast, and your heart rate has gone up quite a bit. Riding a bike on level ground or with few hills.Here are some examples of activities that require moderate effort: One way to tell if it’s a moderate-intensity aerobic activity is that you’ll be able to talk, but not sing the words to your favorite song. Moderate-intensity aerobic physical activity means you’re working hard enough to raise your heart rate and break a sweat. Intensity is how hard your body is working during a physical activity. As long as you’re doing aerobic physical activities at a moderate- or vigorous-intensity, they count toward meeting the aerobic guideline. From pushing a lawn mower, to taking a dance class, to walking or biking to the store – these types of activities and more count.
