HEART RATE INTERVAL™
This program also combines the standard HILL workout profile with the concept of Heart Rate Zone Training. The
default target heart rate is calculated as 80% of the theoretical maximum (HRmax), but the user can adjust the target
rate during the workout setup. The workout alternates between a hill, which brings the heart rate up to the target
rate of 80% of HRmax, and a valley which brings the heart rate down to 65% of HRmax. After a standard three-minute
warm-up, the workout progresses toward the first hill and heart rate goal. Once the goal is reached, the hill continues
for three minutes, then the level decreases into a valley. Once the 65% of HRmax goal is reached, the valley continues
for three minutes, after which the next hill begins. The user's fitness level determines the number of hills and valleys
encountered within the duration. At the end of the duration, the workout goes into a cool down phase. If the heart rate
goes above the theoretical maximum for more then 45 seconds, the cross-trainer automatically goes into pause mode.
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.
