The best workout is the one you do. The easy-to-use Polar M200 with wrist-based heart rate monitoring motivates and guides you every step of the way. The M200’s built-in GPS keeps track of your pace, distance and altitude. After your run, you can see your route on Polar Flow. The M200 tracks your steps, activity, sleep and calories 24/7, encouraging you to stay active every day. Heart rate training is one of the most effective training methods. Measure your heart rate from the wrist and see your current heart rate zone on the screen.
