How Often Should You Exercise
Consult a physician before you start an exercise program. Stop exercising if you feel pain or tightness in
your chest, become short of breath, or feel faint. Contact your doctor before you use the machine again.
Use the values calculated or measured by the machine’s computer for reference purposes only. The heart
rate displayed is an approximation and should be used for reference purposes only.
• 3 times a week for 20 minutes each day.
• Schedule workouts in advance and try to follow the schedule.
Seat Adjustment
Correctseatplacementencouragesexerciseefciencyandcomfort,whilereducing
the risk of injury.
1. With a Pedal in the forward position, place the heel of your foot to the lowest part
of it. Your leg should be bent slightly at the knee.
2. If your leg is too straight or your foot cannot touch the Pedal, you need to move
the seat downward. If your leg is bent too much, you need to move the seat
upward.
Step off the machine before you adjust the seat.
3. Loosen and pull the Seat Post Adjustment Knob on the Seat Post. Adjust the seat
to the desired height.
Do not lift the Seat post above the “STOP” mark on the Seat Post.
4. Release the Seat Post Adjustment Knob to engage the locking pin. Be sure that
the pin is fully engaged and fully tighten the adjustment knob.
5. To move the seat closer to, or away from the console, loosen the seat adjustment knob. Slide the seat to the desired
position and fully tighten the knob.
Note: When the Seat is at the lowest position, the Frame can interfere with turning the handle. Pull the handle and turn it,
then releaase it to engage the locking mechanism at the new position.

1. Be sure that the arrow on top of the Pedal points forward.
2. Push the cleat down and forward to engage the Pedal.
3. Repeat for the other foot.
4. Practice engaging and disengaging from the Pedals before starting your workout.
To disengage (release) the cleats from the pedals, push
the heels outward and lift.

Handlebar to the desired height.
Do not lift the Handlebar Post above the “STOP” mark on the Handlebar Post.
2. Release the Handlebar Post Adjustment Knob to engage the locking pin. Be sure that the
pin is fully engaged and fully tighten the adjustment knob.
NOTICE: Do not crimp the cables.
3. To move the Handlebar closer to, or away from the console, loosen the Handlebar
Adjustment Knob. Slide the Handlebar to the desired position and fully tighten the knob.
Note: When the Handlbar is in the position nearest to the rear, the Frame can interfere with
turning the handle. Pull the handle and turn it back, then push it in to engage and turn it.
