Product Description:
The Polar A3 Heart Rate Monitor helps you focus on the only truly
accurate measurement of whether or not your training is working the
way you want it to. The amount of time you train, the ache in your
lungs, the soreness in your muscles, the calories you burn: all part
of the process and the big picture. But the heart rate is the true
gauge of how you're doing, and that's where the Polar A3 comes in.
