Upgrade the way you train with the Hykso Punch Tracker System. These two powerful sensors attach to your wrists to offer impeccable feedback. Both of the Punch Trackers track at a rate of 1000 times per second. With these incredible metrics, the system can determine how many punches you complete, the velocity, and, most amazingly, the type. Having these metrics in front of you will help you get 6% faster and train up to 21% harder each session. The app delivers live feedback right to your device. You can clue into your numbers so you can improve in real time rather than waiting until your next session. In addition, the app records your metrics so you can see and review your progress. Best of all, the Hykso app connects you to other users to drive your competitiveness even more.
