Remember that proper nutdtion and adequate rest am essential for successful results. If your goal is to bum fat, adjust the intensity of your exercise until your heart rate is near the lowest number in your training zone as you exercise. For maximum fat burning, adjust the intensity of your exercise until your heart rate is near the middle number in your training zone as you exercise. Aerobic Exercise If your goal is to strengthen your cardiovascular system, your exercise must be =aerobic." Aerobic exercise is activity that requires large amounts of oxygen for prolonged periods of time. This increases the demand on the heart to pump blood to the muscles, and on the lungs to oxygenate the blood. For aerobic exercise, adjust the intensity of your exercise until your heart rate is near the highest number in your training zone. EXERCISE INTENSITY Whether your goal is to burn fat or to strengthen your cardiovascular system, the key to achieving the desired results is to exercise with the proper intensity. The proper intensity level can be found by using your heart rate as a guide. The chart below shows recommended heart rates for fat burning, maximum fat burning, and cardiovascular (aerobic) exemise. BPM HEART RATE TRAINING HOW TO MEASURE YOUR HEART RATE To measure your heart rate, first exercise for at least four minutes. Then, stop exercising and place two fingers on your wrist as shown. Take a six-second heartbeat count, and multiply the result by 10 to find your heart rate. For example, if your six-second heartbeat count is 14, your heart rate is 140 beats per minute. (A six-second count is used because your heart rate will drop rapidly when you stop exercising.) ZONES IliMtEIgW •, iimililgllm ,%e 2o 30 40 50 60 7o 80 WORKOUT GUIDEUNES To find the proper heart rate for you, first find your age at the bottom of the chart (ages are rounded off to the nearest ten years). Next, find the three numbers above your age. The three numbers are your =training zone." The lowest two numbers are recommended heart rates for fat burning;the highest number is the recommended heart rate for aerobic exercise. Each workout should include the following three important pads: A warm-up, consisting of 5 to 10 minutes of stretching and light exercise. A proper warm-up increases your body temperature, heart rate, and circulation in preparation for exercise. Burning Fat Training zone exercise, consisting of 20 to 30 minutes of exercising with your heart rate in your training zone. (During the first few weeks of your exercise program, do not keep your heart rate in your training zone for longer than 20 minutes.) To bum fat effectively, you must exercise at a relatively low intensify level for a sustained pedod of time. Dudng the first few minutes of exercise, your body uses easily accessible carbohydrate calodes for energy. Only after the first few minutes of exercise does your body begin to use stored fat calodes for energy. 9 A cool.down, with 5 to 10 minutes of stretching. This will increase the flexibility of your muscles end will help to prevent post-exercise problems. EXERCISE FREQUENCY may complete up to five workouts each week, if desired. CAUTION: Be sure to progress at your own pace and avoid overdoing it. Incorrect or exceaalve training may result In Injury to your health, To maintain or improve your condition, plan three workouts each week, with at least one day of rest between workouts.
