Interval HRC Ultra Workout
HEART RATE CONTROL
66
HEART RATE CONTROL
Interval HRC Ultra works similarly to Interval HRC, but the
work target heart rates gradually increase through your
workout. The first work segment target is 88% HRmax, and the
last work segment target is 97% HRmax.
The rest segment target is 65%. Note that workload usually
has to be greatly decreased to allow you to reach this low a
heart rate within a desirable time.
