There are some phrases that seem self-explanatory. You figure, you should know what they mean. Maybe you act like you know, but really are not sure.

For example, when you hear that a GPS device designed for fitness measures heart rate–what exactly does that mean? Your heart rate is the number of times you heart beats in one minute. This measurement is expressed as beats per minute or bpm.

It is very important to pay attention to your heart rate while you are exercising. The Garmin Forerunner 301 GPS Fitness Trainer with Heart Rate Monitor has a heart rate monitor that continuously tracks and records your heart rate so you can see whether you’re training too hard or not hard enough.  The Forerunner 301 has three separate sport modes for running, biking and another activity. Your heart rate can vary, so it is important to ask your doctor what is a normal heart rate for you during different activities.

The Forerunner 301 will display your current heart rate zone. This is a range of heart beats per minute that helps you gauge the intensity of your workout and train more effectively. This GPS device is so dynamic that it can learn about and adjust to you. After a few intense runs, Forerunner’s AutoLearn feature calculates your heart rate zones and automatically adjusts them as your fitness level improves.

The Garmin Forerunner 301 GPS Fitness Trainer with Heart Rate Monitor not only gets you where you’re going, it also lets you know if you should keep going.
