Workout intensity is adjusted at any time during the workout by using the arrow keys or the
numeric keypad (CT 9500HR) to increase or decrease either the resistance level or the target
heart rate (Fat Burn and Cardio workouts only).
Changing level. The height of the LEDs in the Workout Profile window represents the amount
of workout intensity. Changes to the resistance level (between 1 and 20) or the speed of pedal-
ing can be used to optimize the workout intensity.
Changing target heart rate. The initial target heart rate † shown is based upon the entered age
and the workout chosen (Fat Burn or Cardio). The user accepts or adjusts the specified target
heart rate during the set-up process. During the workout, the heart rate is transmitted by the
chest strap or by Lifepulse Sensors (CT 9500HR) and is used to control the workout resistance
in order to keep the user in the correct target heart rate zone. The user can adjust the target
heart rate at any time during the workout, using the arrow keys or the numeric keypad (CT
9500HR).
† Defined by the American College of Sports Medicine's "Guidelines for Exercise Testing and
Prescription" as 220 minus the user's age.
