The Wahoo TICKR FIT Optical Heart Rate Monitor Armband offers an alternative to chest straps monitor. With sweat-proof technology and real-time data transfer, you'll be able to track your heart rate and calories burned while you're crushing sprints, putting in some miles on foot, or busting out strength training at the gym.

The TICKR FIT reads blood flow in the arm and sends exercise data Bluetooth and ANT+ to your cycling computer, smartwatch, or apps on your phone for immediate access to data to improve your training. It comes with two different adjustable armbands for users with various arm sizes, ensuring you can cinch things down just right for a fit that's both comfortable and secure. It recharges with an included USB cord for up to 30 hours of battery life in each full charge. Wahoo made the TICKR Fit to run with a huge array of apps including Strava, TrainerRoad, Nike+ Running, Runkeeper, and MapMyFitness, as well as with Apple watches and Apple TV by opting to either plug in directly, or utilizing Wahoo RunFit, Beachbody on Demand, or the 7 Minute Workout app.
