The M51 and M52 heart rate monitors are identical except for the color of the watch casing. That said, the M51 and M52 are excellent fitness tools that combine exercise guidance with valuable information about your workout. A sophisticated, built-in heart rate zone test, automatically determines and guides you to the safest and most effective heart rate zone. A calorie counter will help you manage your weight loss program by letting you know how many calories you burned. The Polar M51 and M52 will also tell you how efficient your workout was by tracking the time you exercised in your heart rate zone, your zone settings and your average heart rate.
The Polar M51 and M52 tracks your total exercise time and the total amount of calories you burned for your current and previous workouts. Sophisticated electronics even tell you how many of your calories burned came from fat and how many from carbohydrates.
The Polar M51 and M52 share all of the same features as the M21 and M22. In addition, the M51 and M52 allow you to have heart rate settings and storage files for two users. A sophisticated and easy to use aerobic fitness test is also included. The M51 and M52 make it easy and rewarding to track your fitness improvements.
