Standard fitness trackers are great for walks, runs, rides, rows, and other repetitive tasks. They're not so good for CrossFit. Built upon the proven Push band wearable, Nexus gives CrossFit detailed insight into their workouts. Using machine learning algorithms, it tracks the volume of strain on your body, the intensity of your workouts, your round splits, your cadence, and your work to rest ratio. It's available now for iOS users, with Android support coming soon.
