Rowing machines are an excellent and effective way to get exercise and muscle tone, thanks to their sliding seat and repetitive rowing motion, that allows the engagement of almost all major muscle groups, without the need for a lot of gear or a lot of space compared to most workout machines. Long renowned as the perfect aerobic exercise, the WaterRower is unmatched with its ability to burn calories within a perceived level of exertion. Low impact and body weight bearing, the WaterRower is perfect for any user, and each one is built from beautiful, rich wood that is sourced only from sustainably-managed forests where growth exceeds removal by 229%. Wood is used for its unique visual appeal, but also for its ability to absorb sound vibration for smooth, quiet operation, as well as it's stable longevity. The Natural edition rowing machine is handcrafted in solid ash wood, and features a Honey Oak stain finished in Danish oil. Designed to require minimal maintenance, the WaterRower will give years of trouble free use.
