No matter the resistance we set or the power we applied, the machine remains sturdy, centered, and even. We amped up the intensity for 2000m sprints and found that the C2 supports consistent effort in a way water resistance can’t. The machine assists in keeping your intensity uniform, because it stores up remaining energy in the spinning flywheel. Comments about the ride feel of both Concept 2s were noticeably brief. As one tester put it, “It’s unremarkable because it’s good,” and leaves you free to focus on the effort you’re putting into your workout.
Outside of resistance type, we found the number-one arbiter of ride feel to be cord quality. Water ergometers tend to employ nylon cords, while air ergometers feature metal chains — a durability factor we anticipated would result in our favoring air. But while all three water rowers aced our expectation of smooth, high-tension strokes, perfecting the chain seems to be more difficult: Some tug with just a slight rumble, others feature bouncy, grinding chains that are incredibly loud, something akin to angry snoring. As for nylon, the best wind and unwind like elastic silk — no slack, no sound, no catching, just perfectly even tension throughout the stroke.
Not a lot to complain about on the Classic rower, but when searching for drawbacks of this rowing machine, the S4 Monitor is the one thing that occasionally comes up. It’s rather basic and it isn’t backlit. Regardless, the monitor has all necessary tracking and features for getting an excellent workout, and in normal lighting there is no problem reading the display.
From a fitness perspective, the WaterRower Natural 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 also low impact, as it removes all the body weight from the ankles, knees, and hips, but still moves the limbs and joints through a full range of motion--from completely extended to completely contracted.
