HEART RATE INTERVALTM

This program also combines the standard HILL workout profile with a Heart Rate Zone Training workout. It alternates between a hill, which brings the heart rate up to the target rate*, and a valley, which brings the heart rate down to 90 percent of the target. After a standard three-minute warm-up, the workout progresses toward the first hill and heart rate goal. When the goal is reached, the hill continues for three minutes. Then, the goal switches to 90 percent of the target heart rate. When the user’s heart rate falls to that goal, the valley continues for three minutes. Then, the program switches back to the target heart rate goal. This pattern continues throughout the duration. The user’s fitness level determines the number of hills and valleys encountered. At the end of the duration, the workout goes into a cool-down phase.

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.

User Example: 80 percent of theoretical maximum (40 year old / 144 recommended THR)

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