The proper ratio of effort is about 75 percent lower body and 25 percent upper body. Ensure you’re hitting that by driving through your legs and keeping your hands relaxed.

The Classic Rowing Machine is generally quiet for a water resistance machine, but some users believed that it was a little noisy.

And most find it motivating to hear the water paddles get louder as they burn more calories.
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.
