Yes!! It’s a common misconception that if you’re looking for the best weight loss results you should workout in your “fat burning zone” at about 60% to 70% of your maximum heart rate. However, the fat burning zone burns fewer calories than working out at the higher intensity “aerobic” zone (70% to 85% of your maximum heart rate). The body may burn a greater percentage of fat in the fat burning zone compared to higher intensities but in the aerobic zone you burn way more total calories AND more fat calories overall than at lower intensities. Of course, caloric burn also depends on a workout’s duration and it is easier to work out longer when exercising at a lower intensity.
Electronic heart monitors, such as Polar products, typically consist of a wristwatch-like display and an electrode-studded chest strap that provide accurate, real-time heart rate information. Using a heart rate monitor can help you pace yourself and can also motivate you to exercise. With your heart rate monitor you can observe if your workouts are helping you to lower your resting heart rate. You can also monitor your workout routine to see if you can maintain the same pace but get your heart to pump more slowly or to see if you can shorten the time it takes your heart rate to return to normal after a workout.
