EXTREME HEART RATE TM
This intense, varied workout is designed to help more experienced users to break through fitness
improvement plateaus. The workout alternates between two target heart rates* as quickly as possi-
ble. The effect is similar to that of running sprints. The user must wear a chest strap or grip the
LifepulseTM sensors throughout the workout.
NOTE: It is recommended that users who run at speeds faster than 4.5 MPH wear the chest strap
and do not use the LifepulseTM sensors.
When setting up the workout, the user enters a target heart rate and selects a walk speed and a
jog speed. After a standard three-minute warm-up, the treadmill accelerates to the jog speed,
and the incline increases, until the user reaches the target heart rate goal. That target rate is
maintained for a stabilizing period. Then, the incline is reduced to 0 percent, and the treadmill
slows to the walk speed. When the heart rate falls to the 75 percent goal, it is maintained there
for a stabilizing period. The program repeats the alternating of speeds and incline levels, contin-
uing this pattern throughout the duration.
If the user does not reach a heart rate goal after five minutes, the MESSAGE CENTER displays
a prompt to increase or decrease speed, depending on whether the workout is in a hill or valley
phase. The program does not proceed to a new heart rate goal until the user reaches the cur-
rent goal.

* The FITNESS TEST design is based on a published study: Ebbeling, Cara B.; Puleo, Elane
M.; Ward, Ann; Widrick, Jeffrey, and Rippe, James M. "Development of a Single Stage
Submaximal Treadmill Walking Test: University of Massachusetts Medical Center, 1991
* Target Heart Rate (THR) is a percentage of the theoretical maximum. For example, a
40-year-old user's THR for the EXTREME HEART RATETM WORKOUT is 153. The workout
program targets a standard 85 percent of the maximum, so the equation would be
(220-40)*.85=153.
