Show Description

Run farther, hike longer, without worrying about charging your watch. With truly impressive battery specs, GPS heartrate monitor and intelligent software, the Apex helps you train smarter. An intuitive dial scrolls through data. The GPS provides speed and distance info, and the heartrate sensor provides pulse-related metrics. Preloaded with dozens of indoor/outdoor sport profiles, there's a mode for you. The Apex also learns how you train, lets you know when your body is ready for more, or when you need to rest. If you take a wrong turn on an uploaded route, the back-to-start feature helps get you home safely. A robust strength training mode targets muscle groups and provides a summary of reps, and sets heartrate data after your workout. COROS app displays a heatmap of muscles worked – and lets you share and download workouts, review activities, receive texts, social media alerts and email.
