How Heart Rate Training Works

How Heart Rate Training Works

Click here for a larger image

To activate heart rate training features on the RC3 GPS all you have to do is add a H2 heart rate sensor chest strap (accessory sold separately.) Here’s how heart rate training works:

When you train, you don’t always have to go faster or harder to get the best results. To reach your goals you just need to listen to your heart rate and train at the right intensity.

During training, there are specific intensity zones, each with a benefit.  These zones are based on a percentage of your maximum heart rate- a number calculated by most Polar heart rate monitors. While training you can use your max heart rate to calculate and follow the recommended zones below. Training in the right zone will help you stay on track to reach your goals.

Zone 1 "Very Light" 50-60%: Improves overall health and helps recovery. Recommended for weight management and active recovery.

Zone 2 "Light" 60-70%: Improves basic endurance and fat burning. Recommended for everybody for longer and frequently repeated short exercises.

Zone 3 "Moderate" 70-80%: Improves aerobic fitness. Recommended for everybody for moderately long exercises.

Zone 4 "Hard" 80-90%: Increases maximum performance capacity. Recommended for everybody for shorter exercises.

Zone 5 "Maximum" 90-100%: Develops maximum performance and speed. Recommended for fit people and athletic training.

(Calculate your Maximum Heart Rate: 200 - Your Age= Maximum Heart Rate.)
