Polar Ignite Fitness Watch
No one wants to do the same workout every day — and in fact, you shouldn't. Using the data it gains from built-in sleep tracking — presented as an easy-to-grok score — and recovery measurement, the Polar Ignite's FitSpark training guide will suggest exercises that will keep you fit without burning you out. It supports over 100 different sports, and tracks things like swimming style, running cadence, and VO2max, as well as your steps, continuous heart rate, calories burnt, distance, route, and altitude using GPS, accelerometers, and Polar's signature Precision Prime heart rate sensor.
