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 percent 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
percent of HRmax, and a valley, which brings the heart rate down to 65 percent 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 percent 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 exercise bike automatically goes into pause mode. The program does not pro-

ceed to a new heart rate goal until the user reaches the current goal.

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 chest strap or grip the Lifepulse

sensors throughout the workout.

When setting up the workout, the user enters a target heart rate. After a standard three-minute warm-up, the intensity
increases, until the user reaches the target heart rate goal of 85 percent of the theoretical maximum

†

(HRmax). That target

rate is maintained for a stabilizing period. Then, the intensity decreases. When the heart rate falls to the 65 percent of
HRmax goal, it is maintained there for a stabilizing period. The program repeats the alternating of intensity levels, contin-
uing this pattern throughout the duration. The program does not proceed to a new heart rate goal until the user reaches
the current goal.

Defined by the American College of Sports Medicine's "Guidelines for Exercise Testing and Prescription" as equal to 220 minus an individual’s age.

* Target Heart Rate (THR) is a percentage of the theoretical maximum (HRmax). A 40-year-old user's recommended THR for the HEART RATE INTERVAL
workout is 144, or 80 percent of the maximum; so the equation would be (220-40)*.80 = 144.
