During the Workout
1. During the heart rate controlled workout, the treadmill will respond every 20 seconds to the
heart rate. The program uses the heart rate to adjust the intensity of the workout. It will adjust
speed and (if necessary) incline to elevate the heart rate to the upper end of the training range,
then it will gradually decrease elevation and (if necessary) speed, to take the user to the lower
target heart rate. A typical 20 minute workout may repeat this pattern 3 - 5 times.
2. The program will display various motivating and interesting information throughout the workout.
After the workout is complete, the program will scroll the summary workout information.
3. If, for any reason, the treadmill does not read your heart rate signal, the treadmill will gradually
decrease the workout intensity. After a heart rate signal is re-established, the interval training
program will resume.
