Fitbit has launched a firmware update for the Charge 2. The update is packed with an upgraded heart rate zone display, guided breathing session, pause and resume workouts, battery life indicator, do not disturb mode, and a new clock face.

The new heart rate zone display lets users see which zone they are in and tells them whether or not their heart is pumping as fast as it should. This enables the user to adjust his/her intensity while working out.

In the guided breathing session, the device will emit a slight vibration which cues the user when to inhale or exhale while closing the eyes. In this manner, the user can enter a deeper state of relaxation thanks to this new feature.

Pausing and resuming workouts will help the user track the time the user is actively working with the simple press of a button.

There's the new battery life indicator. This lets the user know when the device is running low on juice and when to recharge it.

The Do Not Disturb option turns off any notifications by simply putting the device in silent mode, enabling the user to stay focused without any distraction.

Finally, there is a new clock face. The Charge 2 displays the time down to the second which adds to the precision of the user's workout.

With all these updates, Fitbit is making sure that you burn all those holiday fat to keep healthy and fit without any excuses.
