Want to burn up to 1000 calories per hour? Then you need to get one of these. The WaterRower is one of the best tools for burning off calories and getting in shape. Rowing is a full body workout and is one of the highest calorie burning exercises you can do. The WaterRower has something called a ‘WaterFlyWheel’ which emulates the dynamics of a boat moving across the water. The wave-like sound it creates is relaxing and feels like the real thing.
