The heart rate monitor answers the eternal question of how fast is fast and how slow is slow. A heart rate monitor (HRM) is a useful tool to find your target zone of heartbeats per minute. The HRM is your pacer, telling you when to speed up or to slow down to achieve the results you want to get with your workout. However, before starting any exercise program, you should consult a physician to design a program that is well suited for your goals and current condition.
