Interval Program
The Interval Program, available by pressing the INTERVAL
key, is one of the best programs for conditioning your
cardiovascular system. The program raises and lowers your
level of exertion repeatedly through rest and work intervals.
You specify the period of time according to your training
regimen.
Initially, the rest interval is set to 0% grade and 1 mph
(1 kph). The work interval is set at a 3% grade and the speed
remains at 1 mph (1 kph).
While exercising, you can vary the speed and change the
preset incline using the SPEED or INCLINE arrow keys. The
settings are repeated throughout the remainder of the
program.
The display lets you know when the speed setting is about to
change, and indicates the levels of the next interval.
Note: Incline changes are limited to +/–5% grade variance
from the previous incline level.
Random Program
The Random Program can be accessed by pressing the
VARIETY key. Every time the Random program is selected, a
different program profile appears. The columns that appear
in the program profile show the preprogrammed incline. You
can override the preprogrammed incline at any time using
the INCLINE arrow keys.
The incline is preset to zero for the first column. The
maximum change allowed between columns is +/–4%.
The running belt speed is completely under your control. You
can adjust the pace by pressing the SPEED arrow keys.
