The Newest Fitness Trackers We Can't Wait to Sport

The Fitbit Charge HR ($150), announced late last year, is now shipping as of Jan. 6. Similar to the Fitbit Charge, the Charge HR tracks your steps, distance traveled, and sleep, plus displays caller ID when synced with your phone via Bluetooth. Unlike the Charge, however, the Charge HR includes a feature that's becoming more and more prevalent in newer tracker models: a built-in heart rate monitor that continuously tracks your pulse via an LED sensor. It's a great way to measure your resting and active heart rates as well as keep track of your optimal training zone when it's time to sweat.
