Inspect and tighten all parts of the LIFESTYLER® DT1000 regularly. Replace worn parts immediately.

The DT1000 can be cleaned with a soft, damp cloth. Keep liquid away from the electronic monitor. Keep the monitor out of direct sunlight or the display may be damaged. Remove the batteries when storing the DT1000.


If the electronic monitor does not function properly, the batteries should be replaced. See assembly step 5 on page 5 for instructions. In addition, make sure that the sensor wire is connected to the wire on the monitor. See assembly step 6 on page 5.

If the electronic monitor displays incorrect information,

the reed switch should be checked. First, remove the pedal and the side shield from one side of the exer- cise bike.

the sprocket is as close as possible to the reed switch. Loosen the screw in

the reed switch, move the reed switch slightly closer to

the magnet, and tighten the screw. Make sure that the magnet will not hit the reed switch when the sprocket turns. Repeat until the monitor displays correct information.


If the pedals become loose, refer to assembly step 8 on page 5. Tighten the pedal axles into the arms of

the crank. Tighten the 1/2" locknuts on the pedal axles.


The exercise bike features a precision chain that must be kept properly lubricated. Apply a few drops of light multi-purpose oil to the chain every three months.

In addition, the chain must be kept properly adjusted. If the chain is too tight, the bearings may be dam- aged; if the chain is too loose, the fan may be dam- aged. If the chain causes excessive noise or slips as you pedal, check the chain in the following manner:

1. Remove the fan guards from the front of the exer- cise bike. Remove the pedal and the side shield from one side of the exercise bike.

2. Press down on the center of the chain. There should be between 1/4” and 1” of vertical movement in the center of the chain. If the chain is properly adjusted, reattach the side shield, pedal, and fan guards. If the chain needs to be adjusted, see step 3.

3. Loosen both axle nuts. To tighten the chain, turn the adjustment nuts clockwise; to loosen the chain, turn the adjustment nuts counterclockwise. Make sure that the fan is straight and tighten the axle nuts. Reattach the side shield, pedal, and fan guards.


The following general guidelines will help you to plan your exercise program. Remember that proper nutri- tion and adequate rest are essential for successful results.

WARNING: Before beginning this or any exercise program, consult your physician. This is espe-

cially important for individuals over the age of 35 or individuals with pre-existing health problems.


Whether your goal is to burn fat or 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 burn- ing, and cardiovascular (aerobic) exercise.



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, find the three numbers below your age. The three numbers are your “training zone.” The lowest number is the recommended heart rate for fat burning; the middle number is the recommended heart rate for maximum fat burning; the highest number is the recommended heart rate for aerobic exercise.

Fat Burning

To burn fat effectively, you must exercise at a relative- ly 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- 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 your pace until your heart rate is near the lowest number in your training zone as you exercise.

For maximum fat burning, adjust your pace until your heart rate is near the middle number in your training zone as you exercise.

Aerobic Exercise

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 your pace until your heart rate is near the highest number in your training zone as you exercise.


To measure your heart rate, first exercise for at least four minutes. Then, stop exercising and place two fingers on your

wrist as shown.

Take a six-

second heart- O JO) beat count, and GZ) multiply the T

result by 10 to

find your heart

rate. For

example, if your


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.


Each workout should include three important parts: a warm-up, training zone exercise, and a cool-down.

A Warm-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 prepa- ration for strenuous exercise.

Training Zone Exercise Exercise Frequency

After warming up, increase the intensity of your To maintain or improve your condition, complete three exercise until your heart rate is in your training zone workouts each week, with at least one day of rest

for 20 to 30 minutes. (During the first few weeks of between workouts. After a few months of regular

your exercise program, do not keep your heart rate exercise, you may complete up to five workouts each in your training zone for longer than 20 minutes.) week if desired.

A Cool-down The key to success is to make exercise a regular and

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