This is the water rower that provides a full upper body workout, yet takes up to 25% less space than comparable models. Unlike similar units that have the water wheel mounted on the edge of the machine, this model houses the water wheel under the seat, reducing the length of an average machine by 20". The rower provides constant water resistance during each stroke as its flywheel operates against water contained in the five-gallon reservoir. Its LCD monitor displays time, distance, calories, and stroke count, and it also has textured footplates, padded handles, and wheels for portability.  The steel frame and molded seat support 300 lbs. and accommodate users up to 6 1/2' tall.  Monitor requires two AAA batteries. Assembly required. 63" L x 37 1/2" W x 20" D. (75 lbs.)
