Walking is an easy way to get some exercise in your day, and it delivers mental health benefits as well. I’m one of the many people who added daily walks to my routine during the pandemic, and they improved my life so much I don’t intend to stop. But does walking do enough for your body that you can count it as cardio exercise?
The answer is complicated. Walking counts as cardio in some respects: it can burn calories, it gets your heart rate up, and it counts toward the exercise we should all be getting every week. But on the other hand, it’s not going to increase your cardio fitness in the same way as a run or an intense aerobics class would. If you want to improve your endurance, you’ll have to do more than just walking.
