Made by hand in the USA, the WaterRower® Performance Ergometer is designed for fitness enthusiasts and rowers looking for in-depth training data and analysis. The Performance Ergometer features built-in SmartRow technology in place of the S4 Performance Monitor found on the WaterRower® Original Series. SmartRow is an intelligent power meter that provides highly precise measurements of your WaterRower® performance, including your power output. The Performance Ergomoeter includes a folding phone/tablet holder, with performance data wirelessly transmitted via Bluetooth to the free to use SmartRow app (iOS and Android compatible – phone/tablet not included). You can set SmartRow to display the metrics that matter the most to you, including Power (W), Work (J), Energy (kCal), Stroke Length (CM), Average Speed (/500m) and much more. With SmartRow, you can compete live and be ranked against other WaterRower® Performance Ergometer users from around the world, and integrate with fitness tracking apps like Strava and Apple Health. You can even choose from pre-set Beginner, Intermediate or Advanced workouts for guided training too!
