How does the water resistance work? Can I change the resistance to make it harder?
Water resistance is a smooth, natural and exceptionally quiet form of resistance. It's very easy on your back and joints, while still providing an incredible full-body workout. Water resistance scales naturally with your effort; the harder you pull on the rower's handle, the more resistance you'll feel from the water.
This is meant to mimic the sensation of rowing an actual boat -- on water, when you use your oar or paddle to make a deeper stroke, you immediately feel more resistance from the water pushing back against your oar.
