Walking has long been touted as a good form of exercise. It doesn’t require any special equipment and can be done by just about anyone, anywhere, at any time. The benefits are numerous and include burning calories, strengthening bones and muscles and improving mood. But the extent of these benefits depends on your exercise intensity. This can be measured in two ways: your perceived exertion and your heart rate.
Your perceived exertion is merely a subjective measure of how hard physical activity feels to you while you’re doing it. According to the Mayo Clinic, the general guidelines are:
- Your breathing quickens, but you’re not out of breath
- You develop a light sweat after about 10 minutes of activity
- You can carry on a conversation, but you can’t sing a song
- Your breathing is deep and rapid
- You develop a sweat after only a few minutes of activity
- You can’t say more than a few words without pausing for breath
Determining your heart rate can be done in several ways. Some exercise equipment or wearable fitness devices will measure your heart rate. You can also take your pulse manually by placing two fingers on either your wrist, throat or temple. Count the beats for 10 seconds and then multiply by 6 to get your pulse rate per minute.
To get an aerobic or cardio benefit to your walking, it is necessary to keep your heart rate within its “target zone” for a minimum of 15-30 minutes. To calculate your target heart rate, you first need to know your maximum heart rate. This is the upper limit of what your cardiovascular system can handle during physical activity. There are numerous methods for calculating this, but one simple way recommended by both the American Heart Association and the Mayo Clinic is to subtract your age from the number 220. Your target zone varies from person to person and depends on your age. The chart below is a guide.*

*Important note: Some high blood pressure medications lower the maximum heart rate and thus the target heart rate. If you're taking such medicine, or if you have, or suspect, a heart condition, talk to a health care professional before exercising.
So, the next time you go for a walk, increase your intensity by walking at a brisker pace or walking up an incline. Swing your arms and try taking smaller, quicker steps. Make note of your perceived exertion or your heart rate. Try to build up to a moderate or vigorous intensity, and maintain that for several minutes. Gradually increase this on your walks, being careful not to overdo it. Over time you’ll notice your stamina increasing and your fitness level improving.
Don’t want to walk alone? Be sure to check out area hiking clubs and walking groups on the Hoosier Hikers Council website.
