We picked the brains of rowing coaches, fitness experts, and physical therapists to learn what features make for an exceptional rower. Based on their input, we searched the market for air and water resistance rowing machines, then tested the best for ride feel and design. We found one model of each type — air resistance and water resistance — that felt truly superior to the others.
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.
