Yes, walking can be a great cardio workout. The biggest perk of getting your stroll on: 150 minutes (or two-and-a-half hours) of moderate-intensity cardio per week significantly reduces your risk of cardiovascular disease.

In addition to supporting your heart and strengthening your lungs, research shows that walking can also boost your overall energy and immune function, according to Stonehouse.

Also important, though: Walking is a leisure activity you can do on your own to clear your head, spend time with your pet, or be distant, but social, with other people—all of which can be seriously relaxing.
