How do I exercise to lose body fat?
Any form of exercise is better than none at all for losing body fat and to benefit from the positive changes mentioned above. Any exercise which requires you to use your muscles will cause your body to burn fat after the exercise is over - during the "recovery phase" when your body is rebuilding and recovering. To burn fat during exercise, however, certain conditions must be met. Your body has different energy "pathways" which burn either fat or sugar during exercise as the primary fuel. Following the simple guidelines below will ensure that your body burns fat during, as well as after, exercise:
• Type of activity. The best exercises for burning fat are those which can be done continuously and involve the most muscle groups (especially the large muscles of the hips and legs). The more muscles used, the more fat you will burn. Exercises which involve movement for brief spurts followed by rest (even through they may be strenuous), use sugar - not fat - as their primary fuel source.
Fat-Burning Exercises
(Continuous)
Walking
Jogging/running
Aerobic dancing
Jumping rope

Stair climbing
Mini-trampoline
Rowing
Hiking
Sugar-Burning Exercises
(Stop and Go)
Sprinting
Tennis
Racquetball
Calisthenics
Basketball
Downhill Skiing
Square Dancing
Golf
Keep in mind that the exercises in these categories are not black and white. Some exercises are just more efficient for burning fat than others. Even though tennis is a stop and go activity, it will burn more fat in the "recovery phase" than golf simply because it requires more work. Also, since stair climbing uses only the muscles of the legs, it doesn't burn as much fat as cross country skiing which involves both upper and lower body muscles. There is no one "best" exercise for burning fat among those listed; anyone who says there is, is probably trying to sell you something. The key is movement! To burn fat, you have to use your muscles; and to use your muscles you have to move. Just remember, any exercise is good for you. But, the more muscles you use and the more continuous you use them, the more fat you'll burn.
• Intensity. This refers to your level of exertion or "pace" during exercise. Although some people still believe that if an exercise doesn't hurt, it isn't doing them any good, the "no pain, no gain" theory doesn't apply to fat-burning. If you exercise at too high an intensity, your body uses sugar as its primary fuel. To burn fat, you should exercise at a moderate, comfortable pace for you (to get the most benefit from exercise, think longer - not harder). A common way to tell if you're at the right intensity is to check your heart rate (pulse) with a Reebok Heart Rate Monitor during exercise since the rate at which your heart beats is directly related to how hard you're exercising. Try to check your heart rate several times during exercise to make sure you're at the right intensity (slow down or stop if you need to). To determine your "fat burning target heart rate," subtract your age from 220 to determine your maximum heart rate. Then take 60% of that number to determine your lower target limit, and 70% to determine your upper target limit. For example, if you are 30 years old:
220 - 30 = 190 (maximum heart rate)
190 x .60 = 114 (lower target limit)
190 x .70 = 133 (upper target limit)
• Duration. This refers to how long you exercise. Twenty minutes is generally considered the minimum to get fat-burning benefit and to increase the growth of fat burning enzymes in your muscles. Although many experts suggest exercising for up to an hour, this depends on your fitness level. If you're just starting out, go for 20 minutes and try to work up from there. Don't worry about the distance you travel while exercising; the time you exercise is what's important, not the distance.
• Frequency. This refers to how often you exercise. Shoot for a minimum of 3 times per week with no more than 2 days of rest between exercise sessions (so you don't lose conditioning). The ideal range is more like 5-6 times per week. If you want to exercise every day, by all means do it; but this again depends on how fit you are. It may be just as effective for you to increase your intensity slightly or your duration on the days you do exercise rather than to add another day. Even the most highly trained athletes need a day off now and then. |
