OPERATION
Seat Adjustment
Proper seat height ensures maximum exercise efficiency and comfort, while reducing
the risk of injury.
1. Place one pedal in the down position, and center the ball of your foot over the center
of the pedal. Your leg should be slightly bent at the knee.
If you leg is too straight or your foot cannot touch the pedal, you will need to lower
the seat. If your leg is too bent, you will need to raise the seat.
2. Dismount the bike, unscrew the adjustment knob on the saddle post and pull out the
locking pin.
Lower or raise the seat to the desired height. Allow the locking pin to engage and
fully tighten in place.
Lower Body Workout
Once you are in position and sitting comfortably, slowly begin pedaling with your arms
relaxed at your sides or with your hands resting on the hand grips as the arm levers
move.
Pedal at an easy pace until you feel secure and comfortable.
To increase the air resistance and workload, increase your pedaling speed.
Upper Body Only Workout
Once you have gained momentum with pedaling, you can experiment with an upper
body only workout technique.
Grasp the hand grips firmly with palms down and place your feet on the foot pegs near
the fanwheel axle. Lean forward at the hips, keeping your back straight and shoulders
down, while continuing to push and pull the arm levers.
Lower and Upper Body Workout
For a complete body workout, grasp the hand grips with palms down. Push and pull the
arm levers as you pedal, keeping elbows low and next to your body.
To exercise all the muscle groups in your arms, vary your hand position on the grips.

WARM-UP and COOL-DOWN
A successful exercise program consists of a warm-up, aerobic exercise, and a cool-down.
Do the entire program at least two and preferably three times a week, resting for a day
between workouts. After several months, you can increase your workouts to four or
five times per week.
WARM-UP
The purpose of warming up is to prepare your body for exercise and to minimize injuries.
Warm up for two to five minutes before strength-training or aerobic exercising. Perform
activities that raise your heart rate and warm the working muscles. Activities may include
brisk walking, jogging, jumping jacks, jump rope, and running in place.
STRETCHING
Stretching while your muscles are warm after a proper warm-up and again after your
strength or aerobic training session is very important. Muscles stretch more easily at these
times because of their elevated temperature, which greatly reduces the risk of injury.
Stretches should be held for 15 to 30 seconds.

DO NOT BOUNCE.
REMEMBER always to check with your physician before starting any exercise program.
EXERCISE PHASE
This is the stage where you put
the effort in. After regular use,
the muscles in your legs will
become more flexible. Work at
your own pace and be sure to
maintain a steady tempo
throughout. The rate of work
should be sufficient to raise your
heartbeat into the target zone
shown on the graph below.
COOL-DOWN
The purpose of cooling down is to return the body to its normal or near normal, resting
state at the end of each exercise session. A proper cool-down slowly lowers your heart rate
and allows blood to return to the heart.
