The Fitstar Personal Trainer app, meanwhile, is receiving a major overhaul that's aimed at giving you better (and more entertaining) guidance. It'll recommend workouts based on your Fitbit device's daily activity data, such as working on your upper body if you ran the day before. There are two certified personal trainers to coach you, and Fitstar Radio gives you a soundtrack for your runs and gym days.

If you happen to own a Blaze, you'll get a pair of upgrades that first appeared on the Charge 2. You now have a better view of your cardio fitness level compared to others in your age group and gender, and there are guided breathing sessions to help reduce your blood pressure and stress levels.

The Fitbit updates will be staggered throughout the early part of the year. The new Fitstar Personal Trainer app is available right now, and Personal Goal Setting will arrive later in January. You'll have to wait until February to get the Blaze features, however, and the Community update will arrive in March for the US and everywhere else later in 2017.
