Waterrower Classic Rower Rowing Machine S4 with Hi-Rise Attachment

WaterRower Classic is handcrafted in USA from solid American Black Walnut wood, finished w/danish oil. WaterRower's patented WaterFlywheel specifically designed to emulate the dynamics of boat moving though water & is unsurpassed in simulation of physical & physiological benefits of rowing. Outfitted with a "water flywheel" consisting of two paddles in enclosed water tank that provide smooth, quiet resistance, just like the paddles in actual body of water. Has no moving parts to wear out over time (even recoil belt & pulleys don't require lubricating or maintaining). More significantly, water tank & flywheel create self-regulating resistance system that eliminates need for a motor. As with real rowing, when you paddle faster, increased drag provides more resistance. When you paddle slower, the resistance is less intense. Unlike conventional rowing machines, which tend to be jerky & jarring, the WaterRower Classic is remarkably smooth & fluid. From a fitness perspective, the WaterRower Classic works 84 percent of your muscle mass, helping tone and strengthen your muscles while burning far more calories than most other aerobic machines. The exercise is low impact, as it removes all body weight from ankles, knees & hips, but still moves limbs & joints through full range of motion--from completely extended to completely contracted. The WaterRower Classic is outfitted with a Series 4 performance monitor that's designed to balance technical sophistication with user-friendliness. Other details include dual rails with four corner wheels that increase seat stability & reduce amount of sweat buildup; frame that flips upright for handy storage; & weight capacity of 1,000 pounds. The WaterRower Classic measures 84lL21Hx22W inches, 117 pounds filled.1 year warranty on frame & components (upgrades to 5 years frame, 3 years components with completion of registration form)
