Extreme Heart Ratetm

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 possible. The effect is similar to that of running sprints. The user must wear a Polar telemetry heart rate 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 Polar telemetry heart rate 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 stan- dard three-minute warm-up, the treadmill accelerates to the jog speed, and the incline increases, until the user reaches the target heart rate goal of 85% of the theoretical maximum† (HRmax). That target rate is maintained for a stabilizing pe- riod. Then, the incline is reduced to 0%, and the treadmill slows to the walk speed. When the heart rate falls to the 65% of HRmax goal, it is maintained there for a stabilizing period. The program repeats the alternating of speeds and incline levels, continuing 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 current goal.
