Let the Life TRNr Heart Rate Monitor keep track of your workouts so you can tune in on training, running, improving, and getting healthier. This sleek ticker utilizes an ECG-accurate heart rate monitor that you can turn on by simply tapping the face, and this watch works without a chest strap so you don't have to run with a slippery strap under your chest. This monitor also uses an advanced 24-hour calorie burn formula to calculate how many calories you burn each day based off of your exercise time in congruence with your heart rate and metabolic intake. The Life TRNr also features a pedometer with a step goal meter to help you work out efficiently, and the workout memory keeps track of your results from the previous week so you can see how quickly you're improving. This watch is water-resistant down to 50 meters, has an EL backlight for your convenience, and displays the time, day, and date.
