Before using your EFX, we recommend that you follow these instructions and go through a
preliminary demonstration of the unit.

When using the EFX, follow these general guidelines:

Before and after a workout, gently stretch your lower body and back to help prevent stiffness
or soreness.

At the beginning of a workout, take several minutes to bring your heart rate into your training
zone, shown in Diagram 13 in Chapter 6.

After your workout, walk slowly for several minutes to cool down your body and lower your
heart rate. Use the cool-down feature on your EFX.

A variety of exercise options are available on the EFX. The course profiles shown on the electronic
console label provide workouts from manual mode to customized courses all with heart rate
interactive capability. (To use the Smart Rate and Heart Rate features, you will need to purchase
and install the Precor Heart Rate Option.)

As you workout, keep in mind that because of the EFX’s unique design, you have several ways of
increasing your work effort:

decreasing the resistance and increasing the strides per minute.

increasing the resistance and keeping the same strides per minute.

increasing both the resistance and ramp settings and maintaining your stride rate.
