From staying in touch to sleep tracking, how to get the most out of your smartwatch

Apple Watches are well-known for their three rings, a quick visual indicator that lets you know how close you are to meeting your daily step, exercise and stand goals. But there’s a lot more to the exercise experience than just that: using the built-in Fitness app, you can tell the watch to track different kinds of workouts, from long walks, to weight training to Tai Chi. No matter what type of exercise you’re doing, the Apple Watch will show you your current workout duration, heart rate and calories burned.
