Calories Burned in Fat Burning Zone Still not convinced that the fat burning zone doesn't really burn more fat? Let's do the math. The chart below details the fat calories expended by a 130-pound woman during a typical exercise session. In this example, the woman burns more total calories and more fat calories at a higher intensity. Calories Burned at Low and High Intensity So, Is Low Intensity Exercise Just a Waste of Time? Before you start doing all your workouts in the high intensity zone, keep in mind that exercising at a high intensity all the time is just not smart. It can easily lead to overtraining, injury, and exercise burnout. Low-intensity cardiovascular exercise has many benefits, and for some people, it is the best way to exercise. One reason some people are better off sticking with a lower intensity workout is that working at the high intensity is difficult. Yes, it's hard work. You can't go very long without running out of fuel, so it's not going to be something you can do for hours on end. Unless you train at a high level, you probably have enough glycogen to last about two hours before you run out of glycogen and need to refuel, or slow down. Refueling with the right food is one way to maintain a high intensity over hours and hours, and why ultra-endurance athletes snack on energy bars, bananas and power drinks. This isn't necessary for most recreational exercisers who rarely work out for more than an hour. If your typical workout routine includes an hour at the gym, you don't need to worry about running out of fuel if you work hard. So going for a high-intensity effort, at least a couple times a week, is a simple way to make the most of your workout time. High intensity workouts aren't for the timid. And they aren't for a beginner. They require a lot of effort and you will need to gradually build up your body to handle those efforts. You can't go from couch potato to high-intensity queen overnight. You need to get your muscles, joints, cardiovascular system, and even your mind prepared to handle the stress, or you could easily overdo it and wind up injured or ill. So, while high intensity gets you fit faster, and burns more calories, low intensity exercise should still have a place in your workout schedule. In fact, longer, slow endurance exercise should be a regular part of a well- balanced, healthy lifestyle. Recovery is faster with low intensity movement. Going for a hike, taking a casual bike ride, or just stretching are excellent low intensity activities. Mix it up with shorter, higher intensity workouts and power training to add variety, burn calories and build endurance quickly. Be smart, listen to your body, and mix up your workouts in the way that works best for your goals and comfort zone. overall calories carbohydrate week, and burning more overall calories from both fat and stored glycogen. While it is true that you burn a higher percentage of calories from fat in the low intensity "fat burning zone," you still burn more total calories, and more calories from fat, at a higher intensity. Pushing your pace, alternating bursts of high and low intensity (interval training), and adding some all-out efforts forces you to activate the anaerobic system (70-90% of your maximum heart rate), which results in a greater number of total calories burned during your workout, which is what ultimately determines fat loss from exercise.
