Most heart-rate monitors require you to wear a bulky chest strap with a sensor that constantly needs to be moistened in dry, cold weather. But the Mio Alpha isn’t like most heart-rate monitors.
The watch-like monitor takes accurate, continuous heart-rate readings through your wrist—no chest strap required.
In workout mode, multi-colored LED lights let you know whether you’re below, within, or above your target heart-rate zones. It connects via Bluetooth with your phone so you can integrate your stats with Strava, Map My Run, and other apps. The easy two-button navigation lets you see your exercise time, average heart rate, and the period you spend “in zone.” It also has a clock and continuous heart-rate display.
