As I identified in my original reply, the guideline to exercise at 60 - 90%
greater than your resting heart rate would have the perverse effect of
causing fitter people (with lower resting heart rates) to exercise at lower
intensities than unfit people. Having never heard of such a thing, its
easier to assume that the OP misunderstood the advice. Have you ever heard
advice of this type? What is the advantage in reducing exercise intensity as
you get fitter?

BTW, where is the evidence that you would use to make a case that exercising
at 90% of your max doesn't develop aerobic potential and ability?
