CONDITIONING GUIDELINES

The following general guideUnes will help you to plan

your exercise program. Remember that proper nutri-

tion and adequate rest are essential for successful

results.

EXERCISEINTENSITY

Whether your goal is to burn fat or strengthen your

cardiovascular system, the key to achieving the

desi_d 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, maximum fat

burning, and cardiovascular (aerobic) exercise.

HEART RATE TRAINING ZONES

To find the proper heart rate for you, first find your age

near the top of the chart (ages are rounded off to the

nearest ten years). Next, look below your age and

find the three numbers in grey boxes. The three num-

bers are your "training zone." The lowest number is

the recommended heart rate for fat burning; the mid-

dle number Is the recommended heart rate for maxi-

mum fat burning; the highest number is the recom-

mended heart rate for aerobic exercise.

Fat Burning

To burn fat effectively, you must exercise at arelative-

ly low intensity level for a sustained period of time.

Dudng the first few minutes of exercise, your body

uses easily accessible carbohydrate caiodes for ener-

gy. Only after the first few minutes of exercise does

your body begin to use stored fat calodes for energy.

If your goal is to bum fat, adjust the intensity of your

exercise until your heart rate is near the lowest num-

ber 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 num-

ber in your training zone as you exercise.

Aerobic Exercise

If your goal is to strengthen your cardiovascular sys-

tem, your exercise must be "aerobic."Aerobic exer-

cise 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.

HOW TO MEASURE YOUR HEART RATE

To measure your heart rate, first exercise for at least

four minutes. Then, stop exercising and pisce two fin-

gers on your

wdst as

shown. Take a

six-second

heartbeat

count, and

multiply the

result by 10 to

find your heart

rate. For

example, if

your six-sec-

ond 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.)

Adjust the intensity of your exercise until your heart

rate is at the desired level. You can adjust the intensi-

ty of your exercise by changing your pedaling speed,

adjusting the pedaling resistance, or using the handle-

bars in the dual-motion position.

WORKOUT GUIDEUNES

Each workout should include the following three parts:

A warm-up, lasting 5 tO 10 minutes. Begin with slow,

controlled stretches, and progress to more rhythmic

stretches to increase the body temperature, heart

rate, and circulation in preparation for strenuous exer-

cise. (See SUGGESTED STRETCHES on page 11.)

Training zone exercise, consisting of 20 to 3_min-

utes of exercising with your heart rate in your training

zone.

A cool-down, with 5 to 10 minutes of stretching.

Thorough stretching helps to offset problems caused

when you stop exemising suddenly. Stretching for

increased flexibility is also most effective after exercis-

ing. A proper cool-down should leave you relaxed and

comfortably tired.

EXERCISE FREQI_IERC¥

To maintain or improve you_ Oond_!on;'pl_l}lthree

workouts each week_ with _t leas_ne da_ of'rest

between workouts. After a few mqnths of r_egularexer-

cise, you may completeup to five Workouts each

week, if desired.

Remember, the key to success is make exercise a

regular and enjoyable part of your everyday life.

SUGGESTED STRETCHES

The correct form for several basic stretches is shown in the

drawings below. Move slowly as you stretch--never bounce.

1. Toe Touch Stretch

Stand with your knees bent slightly and slowly bend forward

from your hips. Allow your back and shoulders to relax as you

reach down toward your toes as far as possible. Hold for 15

counts, then relax. Repeat 3 times. Stretches: Hamstrings,

back of knees and back.

2. Hamstring Stretch

Sit with one leg extended. Bring the sole of the opposite foot

toward you and rest it against the inner thigh of your extended

leg. Reach toward your toes as far as possible. Hold for 15

counts, then relax. Repeat 3 times for each leg. Stretches:

Hamstrings, lower back and groin.

3. Calf/Achilles Stretch

With one leg in front of the other, reach forward and place

your hands against a wall. Keep your back leg straight and

your back foot fiat on the floor. Bend your front leg, lean for-

ward and move your hips toward the wall. Hold for 15 counts,

then relax. Repeat 3 times for each leg. To cause further

stretching of the achilles tendons, bend your back leg as well.

Stretches: Calves, achilles tendons and ankles.

4. Ouaddceps Stretch

With one hand against a wall for balance, reach back and

grasp one foot with your other hand. Bring your heel as close

to your buttocks as possible. Hold for 15 counts, then relax.

Repeat 3 times for each leg. Stretches: Quadriceps and hip

muscles.

5. Inner Thigh Stretch

Sit with the soles of your feet together and your knees out-

ward. Pull your feet toward your groin area as far as possible.

Hold for 15 counts, then relax. Repeat 3 times. Stretches:

Quadriceps and hip muscles.

MAINTENANCE AND STORAGE

Inspe_ and tighten all parts of the PROFORM 770S

regularly. The 770S can be cleaned with a soft, damp

cloth. To prevent damage to the console, keep liquids

away from the console and keep the console out of

direct sunlight.

BATTERY REPLACEMENT

If the console does not function properly, the batteries

should be replaced. To replace the batteries, see

assembly step 4 on page 7.

HANDLEBAR LUBRICATION

moved, a small amount of grease should be applied.

CRANKADJUSTMENT

If the arms of the Crank (17) become loose, they

should be tightened in order to prevent excessive

wear. Loosen the Crank Nut (24) on the left arm of the

Crank, Place the end of a standard screwdriver in one

of the slots in the Slotted Crank Nut (22). Ughtly tap

the screwdriver with a hammer to turn the Slotted

Crank Nut counterclockwise untilthe arms are no

longer loose. Do not overtighten the Slotted Crank
