Moderate-intensity walking is the best cardiovascular exercise. It’s low impact, which means it will reduce the impact on your knees, especially if you’re carrying around more weight than you’d like to admit. It’s important to walk with good posture, because it can increase the number of calories you burn and make your walk more enjoyable.

You want walking to be a total-body experience, not just something that involves your legs. So use your upper body, which will increase your calorie burn. Try using hand or wrist weights 2 to 6 lbs. Be sure to keep your head facing forward, not angled down, and hold your arms at 90-degree angles and pump them in the air as you walk. And when you step, concentrate on pushing off through your heels – not the balls of your feet.

The best part of all is you can power walk anywhere: around your neighborhood, during your lunch break or even at the mall!
