The answer is within.

Maximum heart rate is the maximum number of times the heart should beat before its function could be affected. The target heart rate must be below maximum heart rate, usually 50-85 percent of maximum heart rate. Target heart rate zone is a numerical range someone wants to exercise within. If it is below, a person does not push too hard. If it is above, then the person must slow down in order to avoid reaching maximum heart rate.
