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. For more detailed exercise informa- tion, obtain 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 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 and aerobic exercise.

Aerobic Exercise

If your goal is to strengthen your cardiovascular sys- tem, 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 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 re- sult by ten to find

your heart rate. (A six-second count is used because your heart rate drops quickly when you stop exercis- ing.) If your heart rate is too high or too low, adjust the speed or incline of the treadmill accordingly.

WORKOUT GUIDELINES

To find the proper heart rate for you, first find your age at the top of the chart (ages are rounded off to the nearest ten years). Next, find the three numbers below your age. The three numbers are your “training zone.” The lower two numbers are recommended heart rates for fat burning; the highest number is the recom- mended 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.

Each workout should include the following three impor- tant parts:

A Warm-up

Warming up prepares the body for exercise by increas- ing 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 15).

Training Zone Exercise

After warming up, increase the intensity of your exer- cise until your heart rate is in your training zone for 20 to 60 minutes. (During the first few weeks of your exer- cise program, do not keep your heart rate in your train- ing zone for longer than 20 minutes.) Breathe regularly and deeply as you exercise—never hold your breath.

A Cool-down

Finish each workout with 5 to 10 minutes of stretching to cool down. This will increase the flexibility of your muscles and will help to prevent post-exercise problems.
