The following graph shows how your effective heart
rate ranges vary with your age.
Figure 13: Heart rate target zones
On the Workout List, you can find several heart rate
workouts (refer to Available Workouts). These workout
courses automatically manage your heart rate at a
target level based on your age. By monitoring your
heart rate and making changes to the equipment's
settings as you exercise, the workouts keep your heart
rate within a few beats per minute of the target rate.
