Don’t weigh yourself down with more tech. Suunto’s 3 series uses the GPS you’re already carrying (your phone) to collect training data. The free Suunto app lets your phone communicate with your watch to send notifications, reminders and messages. An optical heart rate monitor takes pulse information straight off your wrist, doing away with the need to wear a finicky chest strap. As it learns your current activity level, the 3 provides you with a personalized training plan that offers live updates, letting you know when to go harder or to slow down. It also adapts if you miss a workout, or if you crush it a bit harder than you have before. If a training plan isn’t your style, the 3 series is has 70 different activity profiles. When you're not training, the activity tracker trackd your steps and calories, and monitors the quality of your sleep. It then takes all of your data into consideration when calculating recovery times and tracking progress.
