Fitbit knows that maintaining a good exercise regimen is as much about motivation as anything else. To that end, it's launching multiple updates to help you stay focused. To start, its core mobile app now has a Community area that makes it easier to keep yourself going. There's a social feed where you and your fitness-minded peers can compete, find nearby workouts, join groups and share achievements. You'll also get advice from Fitbit experts to help refine your routines, and there's a Personal Goal Setting option in the app to help set realistic goals based on your activity.
