Basics of using the heart rate monitor.
Nobody wants a new gadget in his life but using a heart rate monitor is a superb idea to help you get much more out of aerobic exercise. So, WHAT IS IT? It's a simple gadget that tells you how hard your heart is working...in part...





















I sometimes use a heart rate monitor during my commute (by bike). On 5/15/2008, Bike To Work Day, my MHR was 151, AHR was 137. I had another HRM that estimates calories burned. According to that, I burned 9000 calories during one bike ride to San Francisco. I have had a combination HRM and GPS, which I used frequently.
