EXTREME HEART RATETM WORKOUT (93X ONLY)
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 possi- ble. The effect is similar to that of running sprints. The user must wear a Polar chest strap through- out the workout.
When setting up the workout, the user enters a target heart rate. After a standard
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, continuing this pattern throughout the duration. The program does not proceed to a new heart rate goal until the user reaches the current goal.
