Conditioning Guidelines, Exercise Intensity

CONDITIONING GUIDELINES

WARNING: Before beginning this or any exercise program, consult your physician. This is especially important for in- dividuals over the age of 35 or individuals with pre-existing health problems.

The following guidelines will help you to plan your ex- ercise program. RememberÑthese are general guide- lines only. For more detailed exercise information, ob- tain a reputable book or consult your physician.

EXERCISE INTENSITY

Whether your goal is to burn fat or to strengthen your cardiovascular system, the key to achieving the de- sired 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 recom- mended heart rates for fat burning and aerobic exer- cise.

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 at the top of your age. The three numbers are your Òtraining zone.Ó The lower two numbers are recommended heart rates for fat burning; the higher number is the recommended heart rate for aerobic exercise.

Fat Burning

To burn fat effectively, you must exercise at a relatively 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 does your body begin to use stored fat calories for energy. If your goal is to burn fat, adjust the speed and incline of the treadmill until your heart rate is near one of the lower two numbers in your training zone.

Aerobic Exercise

If your goal is to strengthen your cardiovascular sys- tem, 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 speed and incline of the treadmill until your heart rate is near the highest number in your training zone.

HOW TO MEASURE YOUR HEART RATE

To measure your heart rate, stop ex-

ercising and place two fingers on your

wrist as shown. Take a six-second heartbeat count, and multiply the result by

ten to find your heart rate. (A six-second count is used because your heart rate drops quickly when you stop exercising.) If your heart rate is too high or too low, ad- just the speed or incline of the treadmill accordingly.

WORKOUT GUIDELINES

A well-rounded workout includes the following three important parts:

A Warm-upÑStart each workout with 5 to 10 minutes of stretching and light exercise (see SUGGESTED STRETCHES on page 22). A proper warm-up in- creases your body temperature, heart rate, and circu- lation in preparation for exercise.

Training Zone ExerciseÑAfter warming up, increase the intensity of your exercise until your pulse is in your training zone for 20 to 60 minutes. (During the first few weeks of your exercise program, do not keep your pulse in your training zone for longer than 20 minutes.) Breathe regularly and deeply as you exerciseÑnever hold your breath.

A Cool-downÑFinish each workout with 5 to 10 min- utes of stretching to cool down. This will increase the flexibility of your muscles and will help to prevent post- exercise problems.
