Your new treadmill is part of the True Z5 Series treadmills, which
are all built to the same heavy-duty standards. Since this owner’s
guide covers all five Z5 Series models, you might notice explanations
of features that are different from your treadmill. The main
differences are in the consoles. The following section describes the

Calorie Expenditure Calculations
three : BasIC operatIon
True treadmills use the calorie expenditure formula as described in
Guidelines for Exercise Testing and Prescription from the American
College of Sports Medicine. This is the most widely
accepted formula for running and walking.
The ACSM guide says that running burns calories
twice as fast as walking, e.g., a 150-pound person
jogging at 5 mph requires 548 calories per hour, while
walking at 5 mph requires 274 per hour. See Appendix
C for more details.
(Other respected researchers such as David Costill think the ACSM
overstates the energy difference between running and walking.
Costill believes running requires 60% more energy than walking, not
100% as calculated by the ACSM. Using the same example, Costill's
calculations result in 496 cal/hour for running 5 mph, with 313 cal/
hour for walking 5 mph.)
One potential source of calorie estimate
error is that the treadmill doesn't know
if you are running or walking, so it has

to make some assumptions. It assumes
you are walking at 3 mph and slower,
and running at 5 mph and faster. Between those two speeds, the
treadmill combines the walking and running formulas to make its
best guess.

trap
The Z5 Series (except the Z5 Non) can
monitor your heart rate when you wear the
transmitter strap provided. It will display
it as a digital beats-per-minute
readout, and it is very accurate,
typically within one beat per
minute.
Although your treadmill functions fine without using the heart
rate monitoring feature, this kind of monitoring gives you valuable
feedback on your effort level. It also allows you to use the most
advanced training system available on a treadmill: True's Heart Rate
Control, where the treadmill automatically adjusts your workout
level based on your heart rate. See the Heart Rate Control section of
this manual for details.
The transmitter strap should be worn directly
against your skin, about one inch below the pectoral
muscles/breast line.
Women should be careful to place the transmitter
below their bra line.
BasIc operatIon
Some moisture is necessary between the strap and
your skin. Sweat from your exercise works best,
but ordinary tap water may be used prior to your
workout if desired.

One part of True's unique
cushioning and stability
system is the S.O.F.T. System.
It cushions the initial impact
of your foot plant near the
front of the treadmill deck,
then transitions to a firm,
secure surface for push-off.
The combination of softness, then firmness — right when you need
it — reduces stress on ankles, knees, hips, and back.
The other part of True's comfort and performance system is the
S.O.F.T. Select adjustable softness surface on the Z5.4 and Z5.5
Limited. You can adjust the deck support through a 22-inch range
by moving the lever on the right side of the treadmill or, on the Z5.5
Limited model, by pressing the Softer or Firmer keys on the console.
