HEART OF THE MATTER
The watch has a builtin heart-rate monitor, so you’ll know if you’re in the fat-burning zone. It also knows if you’re sitting and will remind you to get moving or, at the very least, stand
up if you’ve been sedentary for too long. It also tracks distance, calories burned and the duration of your workout. And, for the romantics out there, you can email an emoticon of your actual heartbeat.
