Your treadmill, like any other type of sophisticated electronic equipment, can be seriously damaged by sudden voltage changes in your home’s power.

Voltage surges, spikes, and noise interference can result from weather conditions or from other appliances being turned on or off.

To decrease the possibility of your treadmill being damaged, always use a surge suppressor with your treadmill (see drawing 1 at the right).

Surge suppressors are sold at most hardware stores and department stores. Use only a single-outlet surge suppressor that is UL 1449 listed as a transient voltage surge suppressor (TVSS). The surge suppressor must have a UL suppressed voltage rating of 400 volts or less and a minimum surge dissipation of 450 joules.

The surge suppressor must be electrically rated for

120 volts AC and 15 amps.

This product must be grounded.

If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a cord having an equipment-grounding conductor and a grounding plug.

Plug the power cord into a surge suppressor, and plug the surge suppressor into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

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.

heart rate is near one of the lower two numbers in your training zone. It may also be helpful to set the speed control on the console to FAT BURN to help you maintain the proper intensity level. (See page 9.)

Aerobic Exercise

The following guidelines will help you to plan your exercise program. Remember—these are general guidelines only. For more detailed exercise information, obtain a reputable book or consult your physician.

EXERCISE INTENSITY

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 speed and incline of the treadmill until your heart rate is near the higher number in your training zone. It may also be helpful to set the speed control on the console to AEROBIC to help you maintain the proper intensity level. (See page 9.)

High Performance Athletic Conditioning

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.

If your goal is high performance athletic conditioning, set the speed control on the console to PERFOR-

MANCE to help you maintain the proper intensity level.

(See page 9.) Note: During the first few weeks of your exercise program, keep your heart rate near the low end of your training zone.

HOW TO MEA-

SURE YOUR

HEART RATE

To find the proper heart rate for you, first find your age on the left side of the chart (ages are rounded off to the nearest ten years). Next, find the three numbers to the right of your age. The three numbers are your

“training zone.” 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

To measure your heart rate, stop exercising 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 sixsecond count is used because your heart rate drops quickly when you stop exercising.) If your heart rate is too high or too low, adjust the speed or incline of the treadmill accordingly.

WORKOUT GUIDELINES

Each workout should include the following three parts:

Warming Up

Start each workout with 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.

14

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.)

Cooling 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.

Exercise Frequency

To maintain or improve your condition, complete three workouts each week, with at least one day of rest between workouts. After a few months of regular exercise, you may complete up to five workouts each week if desired.

The key to success is to make exercise a regular and enjoyable part of your everyday life.

SUGGESTED STRETCHES

The correct form for several basic stretches is described below. Move slowly as you stretch—never bounce.

1. Toe Touch Stretch
