Aerobic activity or "cardio" gets you breathing harder and your heart beating faster. From pushing a lawn mower, to taking a dance class, to biking to the store – all types of activities count. As long as you're doing them at a moderate or vigorous intensity for at least 10 minutes at a time. Even something as simple as walking is a great way to get the aerobic activity you need, as long as it's at a moderately intense pace.
Intensity is how hard your body is working during aerobic activity.
How do you know if you're doing moderate or vigorous aerobic activity?
On a 10-point scale, where sitting is 0 and working as hard as you can is 10, moderate-intensity aerobic activity is a 5 or 6.
It will make you breathe harder and your heart beat faster. You'll also notice that you'll be able to talk, but not sing the words to your favorite song.
Vigorous-intensity activity is a 7 or 8 on this scale. Your heart rate will increase quite a bit and you'll be breathing hard enough so that you won't be able to say more than a few words without stopping to catch your breath.
You can do moderate- or vigorous-intensity aerobic activity, or a mix of the two each week. Intensity is how hard your body is working during aerobic activity. A rule of thumb is that 1 minute of vigorous-intensity activity is about the same as 2 minutes of moderate-intensity activity.
Everyone's fitness level is different. This means that walking may feel like a moderately intense activity to you, but for others, it may feel vigorous. It all depends on you – the shape you're in, what you feel comfortable doing, and your health condition. What's important is that you do physical activities that are right for you and your abilities.
