Many fitness trackers will allow for a fitness goal to be set, whether it’s step-based or mile-based, and automatically update it as the user moves closer to meeting it. Fitbit Charge HR comes with SmartTrack, a feature that automatically tracks workouts, including walking and running sessions, swimming laps, cycling, gym training and more. After connecting your fitness tracker to the company’s mobile app, you can personalize the tracker and set custom goals for the week. This can help you stay on track and easily update workout plans if your goals are not being met.
