NEW Polar A5 Heart Rate Monitor Wrist Receiver and Transmitter

POLAR A5 - Many exercisers pace themselves by how many sets they do, how long they exercise or how far they go. However, research shows that if exercise doesn't raise your heart rate above 50% of its maximum rate, you may not get the most effective results. And if you exercise too far above your target zone, you'll tire too quickly. The most effective exercise zone is within 65% to 85% of the maximum heart rate. The Polar A5 is an invaluable tool for moderate exercisers who are training for fitness and weight loss.
