Here’s a secret, because the rowing machine provides an intense full body workout, the exercise burns a high amount of calories not only during the actual activity but also for a period after you’ve stopped. This is known as the “after-burn effect”. Essentially, you’ve worked your body so hard that it is forced to keep burning calories and fat even when you’re not rowing. The scientific jargon for this is “excess post-exercise oxygen consumption” or “EPOC” for short. But all you need to know is that if you’re doing an intense rowing workout, the benefits continue after you’re done. How great is that?

Rowing has long been recognized as the perfect aerobic pursuit, with naturally smooth and flowing movements that don't tax the joints but do boost the heart rate. Now you can take your rowing experience to the next level with the WaterRower Classic rowing machine. Using the same principles that govern the dynamics of a boat in water, the WaterRower Classic is outfitted with a "water flywheel" that consists of two paddles in an enclosed tank of water that provide smooth, quiet resistance, just like the paddles in an actual body of water. As a result, the machine has no moving parts that can wear out over time (even the recoil belt and pulleys don't require lubricating or maintaining). More significantly, the water tank and flywheel create a self-regulating resistance system that eliminates the need for a motor. As with real rowing, when you paddle faster, the increased drag provides more resistance. When you paddle slower, the resistance is less intense. The only limit to how fast you can row is your strength and your ability to overcome drag. And unlike conventional rowing machines, which tend to be jerky and jarring, the WaterRower Classic is remarkably smooth and fluid.

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.
