GET OUT OF YOUR COMFORT ZONE!

• Max Fat Burning: Despite what you may have heard about the fat burning potential of low intensity exercise, your max fat burning zone actually occurs at the upper end of your aerobic zone, about 80 percent of your max heart rate. It’s true that working at a lower level of intensity (50 to 65 percent of your max heart rate) is easier to maintain for an extended period of time (an hour or more), and it also allows you to burn a greater percentage of fat calories as compared to carbohydrate calories. Yet minute for minute, this lower level of exertion burns substantially fewer total calories and thus fewer fat calories overall. It’s at approximately 80 percent of max that you experience the largest total amount of fat being burned during the shortest duration of time. Generally, you’ll be able to hold your max fat burning intensity for at least 30 minutes (longer as you become more fit).

Estimate your max-fat-burning heart rate with this test:

• Choose an activity in which you can maintain a consistent intensity, such as running, cycling, skiing, rowing, etc.
• Warm up for 10 to 15 minutes.
• Increase your intensity to the highest heart rate you can comfortably maintain and then hold it for 10 minutes. You should be able to talk, but your sentences will be short and choppy.
• Active recovery should be three minutes. Keep moving but with light resistance or intensity.
• Return to the highest heart rate you can hold for 10 minutes and maintain it.
• Cool down for five to 10 minutes.
• Average your heart rate from the two vigorous 10 minute sessions to determine your estimated max fat burning. (Note: This number should be equivalent to the one displayed on most aerobic equipment.)
