A popular choice among many, the Polar heart rate monitor provides you with an accurate way to track your workouts and ensure you are making good progress.

The main Polar heart rate monitor features that you will find on their watches are the activity time, a calorie counter, the barometer/temperature reading and an altimeter.

The calorie counter on the Polar heart rate monitor will be especially useful for dieters because it will allow them to more accurately gauge how many calories they are burning during their workouts. Since weight loss is a function of burning more than you take in, this essential calculation will be figured out for you.

The barometer function also comes in handy if you are exercising outdoors as it will let you know just how hot or cold it is. Exercising in extreme temperatures can get very dangerous so this is something you need to consider.

Finally the altimeter will help those who are running or cycling at altitudes determine how this might be effecting them. When you exercise in very high altitudes there will be less oxygen present to your body and thus everything may feel harder. Knowing this before you start will help you monitor your performance and effort levels accordingly.

So if you're looking for a top of the line device, definitely give this brand some consideration.
