HRC ULTRA WORKOUT
CHAPTER SEVEN: HEART RATE CONTROL
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
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.
