Monitor the performance of your heart while doing your favorite physical fitness regimen. The sports heart rate monitor is a wrist-top gadget that you can wear like a wrist watch. This innovation has revolutionized cardio-monitoring technology. In the past, traditional probes and cables attached to the chest have been very bulky and uncomfortable to use. During exercises, cables often get in the way and fall off easily.

A sport heart rate monitor has a built-in probe scanner that reads the pulse on your wrist while you jog or do aerobics. It also comes with other features such as a counter that measures the amount of calories you are burning. Other models have built in pedometers that calculate the number of steps you’re making while jogging or walking.
