Important: If you entered your age during the Setup prompts and are wearing the
chest strap, you can adjust the rest or work intervals to keep your heart rate in its
recommended zone. For the weight loss zone, try to maintain your heart rate at the
lower end (55% of maximum heart rate) while in the “rest” intervals and keep it at 70%
of maximum heart rate while in the “work” intervals. See Diagram 27.
To use the interval program, take the following steps:
1. Follow the instructions on page 39, Quick Steps to Working Out.
2. At the PROGRAM prompt, use the
▼▲ key to select the INTV program.
3. Press Enter.
4. Select a workout time. If the workout time entered is an even number, then all
intervals (rest and work) are two minutes long. If the workout time that you
enter is an odd number, then all intervals (rest and work) are two minutes
long, except the last one which will be one minute.
5. Press Enter to proceed to the next prompt. When you’re finished answering
the Setup prompts, the Interval program begins.
To set the resistance level for each interval, take the following steps:
1. When the Rest interval prompt appears, press the Resistance ▼ or ▲ key to
change the resistance level. When the desired setting is displayed, simply
continue working out—you do not need to press Enter.
The EFX returns to the “rest” settings at the beginning of each rest interval
until you readjust it or end your workout.
2. The same procedure applies to specifying the settings for the work interval.
Each time the EFX changes intervals, it informs you by displaying a message. When
you complete the time limit set for the program, the automatic cool-down period begins.
