“The first run I had with the device showed me how comfortable, simple, and easy to use it (the Frontier X) was, but more importantly, it gave me reassurance after years of pushing my body and my heart to its limit, that I hadn’t caused any lasting damage.”

TRAIN IN THE ZONE
THAT'S RIGHT FOR YOU

Set discreet real-time vibration alerts for Heart Rate, Breathing Rate, and Cardiac Strain and nudge yourself into your zone.

"Using the Frontier X makes me stay in that area in which I am exercising enough to strain the heart muscle, therefore train it, but not so much that I precipitate a cardiac event."
