BS - I have run 70 km in this last week. You clearly know
nothing about HR monitoring. Clueless. Essentially, a low RESTING HR indicates fitness. A high EXERCISING HR indicates intensity. If you are exercising and your HR is low, you are chilling and you need to go faster. It does not mean you are fit necessarily. As you get fitter, you will be faster with the same HR. A fit person's HR will rapidly rise and recover in response to exercise (but not as much). An unfit person's will be slower in response to changes in intensity (but more for the same INTENSITY).
So if you are unfit:
* HIGH exercise HR, but you won't make 30 minutes.
If you are slow and lazy:
* LOW exercise HR
If you are Fit:
* HIGH exercise HR for hours because you are exercising intensely = speed.
You are like those people who think Discovery is rewarding unfit people by giving more points for higher HRs. Wrong. Wrong. Wrong. That is why it is combined with a time. You must be very SLOW.
The 'vigorous' range is now definitely high. But for the
moderate range - these people were just expecting to be rewarded for doing almost nothing for their health. Just chilling at the gym.
