The water flywheel is comprised of two paddles encased in an enclosed tank of water. As you pull the cable, the paddles move through the water creating resistance. The beauty of this machine is it uses the mass/density of water. The paddles create the drag, so the harder you pull, the more resistance increases. Think about moving your hands through water. The faster you go, the more dense water feels. The slower you go, the less you feel the resistance. And this type of resistance is excellent for your joints. Click here to read the full review.
* While there is nothing to adjust from row to row on the WaterRower, it is possible to increase or decrease the level of resistance by changing how much water you put in the drum. The monitor is pre-calibrated to match 17 liters of water, but you can change that if you want. More than 17 liters = more resistance, up to the max fill line. This is not something you'll want to change frequently, it's more of a set-it-and-forget-it thing.
As far as “racing”, I said an air rowing machine is better because the Concept2 is the only model used for indoor rowing competitions, setting world records, and entering your actual scores online. It is because their monitor can calculate the drag factor of the flywheel in real time and accurately calculate distance and time. Small changes such as dust build up, air temperature, and humidity will not change the times between different machines because the drag factor is calculated every stroke.
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?
The Classic Rowing Machine is designed is extremely easy to use. Additionally, it has a lot of comfort features in its design. It has an ergonomically shaped handle and padded heel rests that accommodate nearly everyone. Everything on the machine can be adjusted quickly. Because there are no movement parts, maintenance is minimal. Even the computer has a lot of one button operations, so the minute you have the rower assembled, you can get to work.
This twenty minutes duration technique is designed to max your muscles out every interval, and at the same time the recovery periods assist in increasing the efficiency with the fat burning routine. Once you have prepared your rowing machine, set its resistance to four. Perform sets of ten, fifteen and twenty power strokes by pulling to handle towards the torso of your body, like doing a rowing motion. Do this motion as fast as your body permits you to. Separate your power strokes at sixty seconds, putting in only fifty percent the effort you did before this. Repeat this cycle until you have fully rowed for a total of twenty minutes.
Absolutely beautiful piece of functional furniture. I use this rower 3-5 times per week. The display is a little awkward and not nearly as advanced as the competition but for anyone short of a pro, it provides all the basic functions you could want. I've used plenty of rowers in gyms but this was my first purchase for home use. It was an excellent alternative to running outdoors in the winter and as an alternative to running when the legs need a little more recovery time. I have it set in the middle of it's resistance range and it is still plenty challenging. So there is a ton of adjustability in that regard. It's not quickly changed but for a single user device this doesn't matter. It's a different feeling than an air fan but I really like it.
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.
