In their book, Heart 411, Drs. Gillinov and Nissen say:
Fitness companies include heart- rate monitors with treadmills, elliptical trainers, rowing machines, and stationary bicycles, promising to guide people to heart- rate targets that put them in their “fat-burning zone,” “fitness zone,” or some other yet-to-be-defined zone. While cardiologists use the ideas of maximum and target heart rates to evaluate results of exercise stress tests, we have no evidence to support their use in guiding a person’s daily workout. The truth is that you can have an excellent workout at both relatively low and relatively high heart rates. Tailor your workout to how you feel and make sure that you exert yourself—evidence of a good workout will be obvious as the sweat begins to flow.
The most important calculation related to exercise is not your maximum heart rate; it’s determining where in your busy schedule you can fit a 30 thirty-minute workout on most days of the week.
