Aerobic fitness increases the amount of oxygen that is delivered to your muscles, which allows them to work longer. Any activity that raises your heart rate and keeps it up for an extended period of time will improve your aerobic fitness.

As you increase your aerobic fitness, you will notice that you can do more physical activity without becoming out of breath or feeling like your heart is pounding. You will be able to do activities such as playing with children, housework, yard work, or hiking without becoming exhausted as quickly. Many forms of aerobic exercise will also strengthen your muscles and increase your flexibility.

One of the best and easiest aerobic activities is walking. You don’t need special equipment, and it can be done almost anywhere. To get aerobic benefit, you must walk briskly-fast enough to increase your pulse and breathing, but not so fast that you can’t talk comfortably.

Some people start by walking 30 minutes daily during lunch or after work. Others start more gradually, with a 10-minute walk every other day. You can also add up exercise time over the course of a day. Walking 10 minutes 3 times a day is roughly equivalent to walking 30 minutes once a day.
