HOW TO USE THE ELLIPTICAL CROSSTRAINER
HOW TO ADJUST THE PEDALS
The motion of the
pedals is deter-
mined by their
positions on the
flex bars. There
are five positions.
To adjust each
pedal, first loosen
the knob beneath
the pedal. Next,
push the bolt
upward, slide the
pedal forward or backward to the desired position, and
then retighten the knob. Make sure that both pedals
are in the same position.
HOW TO EXERCISE ON THE ELLIPTICAL
CROSSTRAINER
To mount the elliptical crosstrainer, hold the handgrip
pulse sensor and step onto the pedal that is in the low-
est position. Then, step onto the other pedal. Push the
pedals until they begin to move with a continuous
motion. Note: The pedal disks can turn in either
direction. It is recommended that you move the
pedal disks in the direction shown by the arrow
below; however, for variety, you can turn the pedal
disks in the opposite direction.
To dismount the elliptical crosstrainer, wait until the
pedals come to a complete stop. Note: The elliptical
crosstrainer does not have a free wheel; the ped-
als will continue to move until the flywheel stops.
When the pedals are stationary, step off the highest
pedal first. Then, step off the lowest pedal.
HOW TO USE THE HANDLEBARS
The handlebars are
designed to add
upper-body exer-
cise to your work-
outs. Push and pull
the handlebars as
you exercise to
work your arms,
shoulders, and
back.
To exercise only
your lower body,
hold the handgrip
pulse sensor as
you exercise.
CAUTION:Before using the ellipti-
cal crosstrainer, read the following precau-
tions.
• Always hold the handgrip pulse sensor or the
handlebars when mounting, dismounting, or
using the elliptical crosstrainer.
• When you stop exercising, allow the pedals to
slowly come to a stop.
• The pulse sensor is not a medical device.
Various factors may affect the accuracy of
heart rate readings. The pulse sensor is
intended only as an exercise aid in determin-
ing heart rate trends in general.

FEATURES OF THE CONSOLE
The advanced console offers a selection of features
designed to make your workouts more enjoyable and
effective. When the manual mode of the console is
selected, the resistance of the pedals can be changed
with the touch of a button. As you pedal, the console
will provide continuous exercise feedback. You can
even measure your heart rate using the built-in hand-
grip pulse sensor.
The console also offers four Smart programs. Each pro-
gram automatically changes the resistance of the ped-
als and prompts you to increase or decrease your pace
as it guides you through an effective workout.
In addition, the console features two Heart Rate pro-
grams that change the resistance of the pedals and
prompt you to vary your pace to keep your heart rate
near a target heart rate as you exercise.
The console also features iFIT.com interactive technol-
ogy. Having iFIT.com technology is like having a per-
sonal trainer in your home. Using a stereo audio cable
(available at electronics stores), you can connect the
elliptical crosstrainer to your home stereo, portable
stereo, computer, or VCR and play special iFIT.com CD
and video programs (iFIT.com CDs and videocassettes
are available separately). iFIT.com CD and video pro-
grams automatically control the resistance of the ped-
als and prompt you to vary your pace as a personal
trainer coaches you through every step of your work-
out. High-energy music provides added motivation. To
purchase iFIT.com CDs and videocassettes, call
toll-free 1-800-735-0768.
With the elliptical crosstrainer connected to your com-
puter, you can also go to our Web site at www.iFIT.com
and access programs directly from the internet.
Explore www.iFIT.com for more information.
