Take your training to the next level. Bodylink combines advanced GPS and heart rate monitoring technologies to create the perfect coaching system. Using Global Positioning System (GPS) technology, this innovative training tool precisely tracks your speed and distance as you exercise. The integral heart rate monitor informs you when you’re in or out of your target zones and assists you in maintaining a proper rate during any exercise. This ensures that you can perform workouts that are physically demanding and effective. Each function is displayed on the Timex wristwatch, so you can glance at your wrist to see pace, heart rate and distance.
