Fitbit bands automatically track exercise

Fitbit has released an update to some of their major products which makes it easier to track exercise than ever before.

The Charge HR and Surge fitness trackers now features SmartTrack, which automatically knows when you start exercising. The new tech is even smart enough to know what kind of exercise you've started, with the ability to identify running, walking, biking, certain classes (like Zumba) and sports. The important data is all synced back to your Fitbit app on your smartphone or desktop, and you don't have to worry about fiddling with menus before you get moving.

PurePulse has been updated as well and should provide better heart-rate monitoring during high intensity sessions. That will provide better information for making sure you're exercising in the most optimal way possible.
