There's also high-intensity interval training for people who want to push even harder. A barometric altimeter logs stairs climbed and helps runners, cyclists, skiers, and snowboarders on their routes. The Watch learns swimmers' strokes automatically, and wheelchair users can take advantage of chair-specific workouts with a variety of pushing techniques. With more than 12 indoor and outdoor workouts to choose from, including lap and open-water swimming, biking, running, and elliptical, it's easy to stay fit. You can also compete against friends and family and respond to notifications of their progress. Swipe up from the bottom of the Watch to view active calories burned, steps taken, and distance traveled. The Stand ring shows how often you've stood up to take a break from sitting, the Move ring shows how many active calories you've burned, and the Exercise ring shows how many minutes of brisk activity you've completed. The Activity app displays progress made towards your daily activity goals with three intuitive rings that grow the more you move, finally closing when you hit your targets.
