Amazon.com Product Description
Stay within your ideal training and intensity range while jogging or working out with the Polar A4 pulse monitor watch. The strapless watch is easy to use: just press and hold the silver contact button with your fingertips and you’re set.
Knowing your heart rate not only helps you reach yourpersonal fitness goal, but also improves your physical condition in general, as it’s vitally important to train at the appropriate intensity level. If you exercise too hard, you may quit before you reach the real benefit, but if you work out too leisurely, you’ll struggle to lose weight at all.
The A4 helps overcome these problems by encouraging you to map out a complete fitness routine. By itself, the A4 makes a good training aid, but it’s particularly valuable when paired with any Polar transmitter, as the two together offer continuous heart rate monitoring. As a result, you’ll know what your heart rate is throughout your workout, rather than only when you press the button. Plus, the A4 offers all the standard sports watch functions, including an alarm, calendar, stopwatch, backlight, and target zone alarms. The watch also offers a calorie counting function and exercise file record when combined with a chest strap transmitter (not included). Finally, the watch comes with a zippered black nylon carrying case for protection. Check it out at Amazon.com
