CONDITIONING GUIDELINES WARNING: Before beginning this or any exercise program, consult your physician. This is especially important for individuals over the age of 35 or individuals with pre-existing health problems. The following guidelines will help you to plan your exercise program. RememberÑthese are general guidelines. For more detailed information about exercise, obtain a book or consult your physician. EXERCISE INTENSITY Whether your goal is to burn fat or 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. For effective exercise, your heart rate should be maintained at a level between 71.5% and 85% of your maximum heart rate as you exercise. This is known as your training zone. You can find your training zone in the table below. Training zones are listed according to age and physical condition. Training Zone (Beats/Min.) Age Unconditioned Conditioned 20 138-167 25 136-166 30 135-164 35 134-162 40 132-161 45 131-159 50 129-156 55 127-155 60 126-153 65 125-151 70 123-150 75 122-147 80 120-146 85 118-144 133-162 132-160 130-158 129-156 127-155 125-153 124-150 122-149 121-147 119-145 118-144 117-142 115-140 114-139 Burning Fat To burn fat, you must exercise at a low intensity level for a sustained period of time. During the first few minutes of exercise, your body uses easily accessible carbohydrate calories for energy. Only after the first few minutes of exercise does your body begin to use stored fat calories for energy. If your goal is to burn fat, adjust the intensity of your exercise until your heart rate is near the low end of your training zone as you exercise. WARNING: The pulse sensors are not medical devices. Various factors, including your movement, may affect the accuracy of heart rate readings. The pulse sensors are intended only as exercise aids in determining heart rate trends in general. Aerobic Exercise If your goal is to strengthen your cardiovascular system, your exercise must be Òaerobic.Ó 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 middle of your training zone. WORKOUT GUIDELINES Each workout should include the following three important parts: (1) a warm-up, (2) training zone exercise, and (3) a cool-down. Warm-up Warming up prepares the body for exercise by increasing circulation, delivering more oxygen to the muscles, and raising the body temperature. Begin each workout with 5 to 10 minutes of stretching and light exercise to warm up (see SUGGESTED STRETCHES on page 25). Training Zone Exercise After warming up, increase the intensity of your exercise until your heart rate is in your training zone for 20 to 60 minutes. (During the first few weeks of your exercise program, do not keep your heart rate in your training zone for longer than 20 minutes.) Breathe regularly and deeply as you exerciseÑnever hold your breath. 24
