Polar is taking their heart rate monitor experience and making it live, on-screen for health club group exercise classes, like spinning. Class members simply wear a Polar chest strap (no watch required), and their live heart rate data (% of max HR, target zones) is beamed onto a digital checkerboard screen. The data helps people know exactly how hard they’re working, and get training guidance with the target zones. You can read the full press release here.
