Random; Manual - Life Fitness 9100 Operation Manual

Each column, as seen in the WORKOUT PROFILE WINDOW and the chart above, represents
one interval. The overall duration of the workout determines the length of each interval. Each
workout is made up of 20 intervals, so the duration of each interval is equal to the duration of
the entire workout divided by 20.
1 to 9 minutes: A workout with a duration of less than 10 minutes is insufficient for the HILL
program to complete all four phases adequately. The program, therefore, condenses a workout
of this duration at various stages.
10 to 19 minutes: The interval durations initially are set at 30 seconds for a 10-minute workout.
For every minute over 10, each interval increases by three seconds. A 15-minute workout
consists of 20 intervals at 45 seconds each.
20 to 99 minutes: All intervals last 60 seconds. If the user adds minutes to the pre-set duration
while the workout is in progress, the program adds hills and valleys that are identical to the first
eight intervals of the Interval Training phase. This pattern repeats until the workout is completed.
R
ANDOM
The RANDOM program creates a terrain of hills and valleys that varies with each workout. More
than one million different patterns are possible.
M
ANUAL
The MANUAL program sets an intensity level that does not change automatically. While the work-
out is in progress, increase or lower the intensity level as desired, using the SPEED and/or
INCLINE ARROW keys.
