I know some people like the definite quantification of having heart rate numbers, but individuals vary in this as in all other bodily measures. A friend's husband was getting extremely frustrated that he was not getting his heart rate up in his "target zone". He finally brought it up with his doctor, who told him that a lifetime of athletic activity had adapted his heart to have a larger than average stroke volume, which meant that his heart was very strong and efficient, pumping more blood per beat, and didn't need to be in the "target zone" to support vigorous activity. Numbers can be a guideline, but they are not the end-all and be-all.
