What makes the Frontier X unique?

How does the Frontier X keep your heart safe?

The Frontier X measures changes in your ECG, indicating oxygen deprivation and heart muscle damage. The device subsequently provides your Cardiac Strain values in real-time on our app. It also warns you with a double-vibration alert if you cross your pre-set threshold, helping you exercise at an exercise intensity that is safe for your heart. This alert can tell you whether you should finish the last lap, run that extra mile, do those last few push ups, or just give your heart a rest.

How does the Frontier X improve your performance?

The Frontier X measures both, Breathing Rate and Heart Rate. Breathing rate is much more closely correlated with your true internal effort than heart rate, because unlike heart rate, it is not influenced by external factors like caffeine, lack of sleep, temperature, humidity and stress, which are some of the problems with heart rate based training. The Breathing Rate based alerts on the Frontier X tell you when to speed up and when to slow down, enabling you to optimize your performance.
