FEATURES OF THE CONSOLE
The advanced console offers an array of features
designed to make your workouts more effective and
enjoyable.
When you use the manual mode of the console, you
can change the resistance of the pedals with the touch
of a button. While you exercise, the console will dis-
play continuous exercise feedback. You can also
measure your heart rate using the handgrip pulse sen-
sor.
The console also offers twenty-four preset twelve hill
climbing workouts and twelve interval workouts. Each
workout automatically changes the resistance of the
pedals and prompts you to vary your pedaling speed
as it guides you through an effective workout.
The console also features an iFit training mode that
allows your console to communicate with your wire-
less network through an optional iFit Live module.
With the iFit Live mode, you can download personal-
ized workouts, create your own workouts, track your
workout results, and access many other features. See
www.iFit.com for complete information.

3. Begin pedaling to start the workout.
Each workout is divided into one-minute seg-
ments. One resistance level and one target speed
are programmed for each segment. Note: The
same resistance level and/or target speed may be
programmed for consecutive segments.
The workout profile will
show your progress.
The flashing segment
of the profile represents
the current segment of
the workout. The height
of the flashing segment
indicates the resistance level for the current seg-
ment.
When the first segment of the workout ends, the
target speed and the resistance level for the sec-
ond segment will appear in the display for a few
seconds to alert you. The next segment of the pro-
file will begin to flash, and the pedals will
automatically adjust to the resistance level for the
next segment.
As you exercise, keep your pedaling speed near
the target speed for the current segment.
The target speed
meter will show
your pedaling
speed and the tar-
get speed for the
current segment.
When the words
SPEED UP appear
in the target speed
meter, increase
your pedaling
speed. When the
words SLOW DOWN appear, decrease your ped-
aling speed.
IMPORTANT: The target speed is intended only
to provide motivation. Your actual pedaling
speed may be slower than the target speed.
Make sure to pedal at a speed that is comfort-
able for you.
If the resistance level for the current segment is
too high or too low, you can manually override the
setting by pressing the Resistance buttons.
IMPORTANT: When the current segment of the
workout ends, the pedals will automatically
adjust to the resistance level for the next seg-
ment.
The workout will continue in this way until the last
segment ends.
To stop the workout at any time, stop pedaling. A
tone will then sound. If the time display mode is
selected, the time will begin to flash in the display.
To restart the workout, simply resume pedaling.
