HRC Ultra Workout
CHAPTER SEVEN: HEART RATE CONTROL
44
Unlike Constant and Interval HRC, you don’t pick a target heart
rate, but you must enter your age correctly.
For the first fifth of your workout time, HRC Ultra tries to
increase your heart rate to 70% of your maximum heart rate
(HRmax) within three to four minutes.
In the middle three-fifths of your workout, HRC Ultra increases
your heart rate to 88% HRmax within three to four minutes, and
then maintains that heart rate.
During the final fifth of your workout, HRC Ultra tries to raise
your heart rate to 97% HRmax by the time you reach one minute
to go in your workout time.
Note: if you prefer lower (“less Ultra”) heart rate targets in either
Ultra workout, you can reduce the targets across the board by
pressing the key.
