Interval Programs
The Interval Programs, available by pressing the INTERVAL
key, are among the best for conditioning your cardiovascular
system. Each program raises and lowers your level of
exertion repeatedly for the specified period of time.
Four programs let you choose the rest and work intervals
according to your training regimen. In the Custom Interval
Program, you specify the duration of the rest and work
intervals.
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 or incline levels
are 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.
