HOW TO USE THE STEPPER  
Note: If there is a thin sheet of clear plastic on  
the face of the console, remove it.  
The innovative console offers a manual mode and  
three pacer programs. The pacer programs are  
designed to help you achieve your exercise goals by  
pacing your exercise. The console also features six  
monitor modes that provide continuous exercise feed-  
back.  
The three graphs on the console show how the target  
pace will change during the pacer programs (see the  
drawing above). Each graph is divided into ten  
columns, and each column represents a two-minute  
time period. The bars in each column show what the  
target pace will be during that two-minute period. For  
example, in the first column of graph 2, there is one  
bar. This shows that during the first two minutes of  
program 2, the target pace will be 40 repetitions  
(steps) per minute (see the scale at the right end of  
the graph). In the second column, there are three  
bars. This shows that during the second two-minute  
period, the target pace will be 60 repetitions per  
minute. Each pacer program is twenty minutes long.  
HOW THE PACER PROGRAMS OPERATE  
When you use a

bars will appear in

column will show your actual pace. The target pace  
will change periodically during the program; as the tar-  
get pace changes, simply adjust your pace to keep  
both columns at the same height. Important: The tar-  
get pace is a goal pace. Your actual pace may be  
slower than the target pace, especially during the  
first few months of your exercise program. Be  
sure to exercise at a pace that is comfortable for  
you.  
¥ Reps/MinÑThis mode shows your pace, in repeti-  
tions (steps) per minute.  
¥ TimeÑIf you select one of the three pacer pro-  
grams, this mode will count down the time remain-  
ing in the program. If you select the manual mode,  
this mode will count up the length of time you have  
exercised. Note: If you stop exercising for ten sec-  
onds or longer, the time mode will pause.

ing that the target pace is 40 repetitions per

in the right column. As the program progresses,  
the target pace will change periodically; as the tar-  
get pace changes, adjust your pace to keep both  
columns at the same height. Remember, the tar-  
get pace is a goal pace. Your actual pace may  
be slower than the target pace, especially dur-  
ing the first few months of your exercise pro-  
gram. Be sure to exercise at a pace that is  
comfortable for you.

HOW TO EXERCISE ON THE STEPPER  
HOW TO ADJUST THE RESISTANCE  
Place the stepper on a level surface and place a mat  
under the stepper. (The stepper features precision  
hydraulic cylinders. However, there is a possibility of  
slight oil leakage due to the nature of hydraulic cylin-  
ders.)  
To change the stepping resistance, simply turn the  
resistance collars on the upper ends of the Resistance  
Cylinders (9) (see the inset drawing). The arrows on  
the Resistance Cylinders and the markings on the  
resistance collars show which resistance level has  
been selected. Make sure that both Resistance  
Cylinders are at the same resistance setting.  
Hold the handlebars and step onto the pedals. Begin  
stepping, alternately depressing the right and left ped-  
als with a smooth, continuous motion. Because the  
pedals move independently of each other, you must  
maintain a continuous motion or both pedals will sink  
to the floor. Change the height of your step or the  
stepping pace until you can comfortably maintain a  
continuous motion.

As you step, you can exercise your upper leg mus-  
cles by keeping your feet flat on the pedals. To focus  
on your calf muscles, rise on your toes as you step.  
Stand erect or lean forward slightly as you exercise.  
Always keeping your back straight in order to avoid  
injury.  
WARNING: The resistance cylinders become very  
hot during use. Touch only the resistance collars  
when changing the stepping resistance.

sure that the Magnet will not hit the Reed Switch when  
the Right Pedal Leg is moved. Repeat until the con-  
sole displays correct feedback.  
REED SWITCH ADJUSTMENT  
If the console does not function properly, or if the dis-  
play becomes faint, the batteries should be replaced.

CONDITIONING GUIDELINES  
The following guidelines will help you to plan your  
exercise program. Remember that proper nutrition  
and adequate rest are essential for successful results.  
gy. 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 lowest num-  
ber in your training zone as you exercise.  
WARNING: Before beginning this or any exer-  
cise program, consult your physician. This is  
especially important for persons over the age  
of 35 or persons with pre-existing health  
problems.  
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 Òaerobic.Ó 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.  
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 recom-  
mended heart rates for fat burning, maximum fat  
burning, and cardiovascular (aerobic) exercise.  
HOW TO MEASURE YOUR HEART RATE  
To measure your  
heart rate, first exer-  
cise for at least four  
minutes. Then, stop  
exercising and place  
two fingers on your  
wrist as shown. Take  
a six-second heart-  
beat count, and mul-  
tiply the result by 10  
to find your heart rate. For example, if your six-second  
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.)  
WORKOUT GUIDELINES  
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  
Òtraining zone.Ó The lowest number is the recommend-  
ed heart rate for fat burning; the middle number is the  
heart rate for maximum fat burning; the highest  
number is the heart rate for aerobic exercise.  
Each workout should include the following three parts:  
A warm-up, consisting of 5 to 10 minutes of stretch-  
ing and light exercise. A proper warm-up increases  
your body temperature, heart rate, and  
circulation in preparation for exercise.  
Training zone exercise, consisting of 20 to 30 min-  
utes of exercising with your heart rate in your training  
zone. (During the first few weeks of your exercise pro-  
gram, do not keep your heart rate in your training  
zone for longer than 20 minutes.)  
Burning Fat  
To burn fat effectively, you must exercise at a rela-  
tively low intensity level for a sustained period of time.  
During the first few minutes of exercise, your body  
uses easily accessible carbohydrate calories for ener-

workouts. After a few months of regular exercise, you  
may complete up to five workouts each week, if  
desired. Caution: Be sure to progress at your own  
pace and avoid overdoing it. Incorrect or excessive  
training may result in injury to your health.  
EXERCISE FREQUENCY  
To maintain or improve your condition, plan three work-  
outs each week, with at least one day of rest between  
Remember, the key to success is make exercise a  
regular and enjoyable part of your everyday life.
