Advanced Health and Fitness Tracker with GPS, Stress Management, Sleep Tracking, and 24/7 Heart Rate Monitor.

• You can connect the Charge 6 to certain exercise machines and see your heart rate right on the screen. With over 40 types of exercises to choose from, like running, biking, or strength training, you can set your own goals and track how you're doing. It also helps you know if your body is ready for exercise or if you need more rest. Watching your heart rate helps you know if you're burning fat or pushing harder. The more time you spend in the cardio or peak zones, the more credit you get for working out.
