Out for a nice run with the Wahoo TICKR X! What do you want most during your run? Information about your heart rate! The heart rate sensor provides this, and that's not all it does. It remembers your exercises, which you can later synchronize with your phone. The built-in accelerometer registers your body's movement and run posture. Using this information, it measures your step frequency, the ground contact time, and the step hight in your run posture. The TICKR X can be used in combination with several popular apps, like Runkeeper and MapMyRun. You can get the most out of the TICKR X with the Wahoo TICKR X Workout. This app recognizes all your exercises, from jumping jacks to squats. The app will also notify you if you're doing an exercise wrong. This way, you get the most from your workout.
