Rowing is a cyclic (or intermittent) form of propulsion such that in the quasi-steady state the motion of the system (the system comprising the rower, the oars, and the boat), is repeated regularly. In order to maintain the steady-state propulsion of the system without either accelerating or decelerating the system, the sum of all the external forces on the system, averaged over the cycle, must be zero. Thus, the average drag (retarding) force on the system must equal the average propulsion force on the system. The drag forces consist of aerodynamic drag on the superstructure of the system (components of the boat situated above the waterline), as well as the hydrodynamic drag on the submerged portion of the system. The propulsion forces are the forward reaction of the water on the oars while in the water. Note also that the oar can be used to provide a drag force (a force acting against the forward motion) when the system is brought to rest.
One downside of the Waterrower for me are the footrests. Whilst they are perfectly adequate if you want to row in shoes, rowing barefoot, which is something I like to do, is impossible. The plastic is completely square at the bottom and has sharp edges that cut into your heels. I also found that my shoes get caught when trying to put them in and out of the holders, which is a bit irritating.
Unlike most other non-combat sports, rowing has a special weight category called lightweight (Lwt for short). According to FISA, this weight category was introduced "to encourage more universality in the sport especially among nations with less statuesque people". The first lightweight events were held at the World Championships in 1974 for men and 1985 for women. Lightweight rowing was added to the Olympics in 1996.
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.
Rowing machines were first used in Archaic Greece. Chabrias, an Athenian military general in 4th Century B.C., invented wooden rowing simulators for his inexperienced oarsmen. This enabled them to learn technique and timing before stepping foot on actual water crafts. And it must have worked — Chabrias successfully led numerous naval attacks against the Spartans.
Women row in all boat classes, from single scull to coxed eights, across the same age ranges and standards as men, from junior amateur through university-level to elite athlete.[49][50] Typically men and women compete in separate crews although mixed crews and mixed team events also take place.[51] Coaching for women is similar to that for men.[52] The world's first women's rowing team was formed in 1896 at the Furnivall Sculling Club in London.[53]
Not a lot to complain about on the Classic rower, but when searching for drawbacks of this rowing machine, the S4 Monitor is the one thing that occasionally comes up.  It’s rather basic and it isn’t backlit. Regardless, the monitor has all necessary tracking and features for getting an excellent workout, and in normal lighting there is no problem reading the display.
 Bring the unparalleled full-body workout of on-the-water rowing home with the premium design and feel of the XTERRA Fitness ERG600W Water Rower. The full body rhythmic nature of rowing makes it wonderfully efficient at burning calories while also developing flexibility and strength. Plus, the "zen-like" water movement you hear from the ERG600W multi-bladed impeller can be soothing and meditative. The large and easy to read 5.5" LCD console with height and angle adjustment includes motivating programmable modes to keep you involved, inspired, and reaching your goals.
The Challenge AR features an advanced computer monitor providing the rower with measurable performance output, an ergonomically designed seat that rides on precision bearings and rollers for absolute smoothness, an upgraded footboard with advanced heel support, and an innovative soft grip handle to eliminate stress on the hands and wrist during the comfortable, but physical workout.
One of the most common brand of ergometers is Concept2.[33] The company offers multiple types of models, including the Model D, Model E, and the dynamic rower. An updated Rowperfect brand of dynamic rowers, RP3, produces ergometers that more naturally mimic the feel and resistance of rowing in a shell on the water. It additionally, shows a dynamic force curve of power that provides the rower with detailed information about their stroke which they can use to improve technique and get stronger.[34]
I am happy with this rowing is quiet and offers good resistence without puttong too much stress on my joints...HOWEVER...the electronic counter has NOT worked from day one!!!..pulling the handle does NOT activate the meter at all!...I hve pluged in the wires and repeated that process SEVERAL times..BUT...nothing!!...I can activate the meter is USELESS for registering any rowing activity!!..As I said...good rower....USELESS Eleconic meter!!!
With the smaller boats, specialist versions of the shells for sculling can be made lighter. The riggers in sculling apply the forces symmetrically to each side of the boat, whereas in sweep oared racing these forces are staggered alternately along the boat. The sweep oared boat has to be stiffer to handle these unmatched forces, so consequently requires more bracing and is usually heavier – a pair (2-) is usually a more robust boat than a double scull (2x) for example, and being heavier is also slower when used as a double scull. In theory this could also apply to the 4x and 8x, but most rowing clubs cannot afford to have a dedicated large hull which might be rarely used and instead generally opt for versatility in their fleet by using stronger shells which can be rigged for either sweep rowing or sculling. The symmetrical forces also make sculling more efficient than rowing: the double scull is faster than the coxless pair, and the quadruple scull is faster than the coxless four.
The Water Rower comes partly preassembled in two large boxes. The assembly instructions are reasonably good, and as long as you take your time and follow them carefully (read all the text) it takes about 45 minutes from opening the first box to trying it out. I bought bottles of distilled water to fill it, which made it easy to fill using the included funnel & hose.
Cardiovascular training involves any activity that requires the use of the large muscle groups of the body in a regular and uninterrupted manner. Rowing is one of the few non-weight bearing sports that exercises all the major muscle groups. In addition, the consistent and all encompassing activity associated with rowing, combined with being outdoors on the water, has an unparalleled impact on reducing stress.2

No matter the resistance we set or the power we applied, the machine remains sturdy, centered, and even. We amped up the intensity for 2000m sprints and found that the C2 supports consistent effort in a way water resistance can’t. The machine assists in keeping your intensity uniform, because it stores up remaining energy in the spinning flywheel. Comments about the ride feel of both Concept 2s were noticeably brief. As one tester put it, “It’s unremarkable because it’s good,” and leaves you free to focus on the effort you’re putting into your workout.

Real Water Resistance: Because the Stamina Wave Water Rowing Machine incorporates water resistance, users will truly feel as though they are out on the lake or river. Water resistance makes the rowing stroke smoother and more consistent, but most importantly, it offers infinite resistance. Just like rowing on water, faster, harder pushes increase the resistance. To further increase or decrease the resistance, you can add or remove water with the included siphon. Even more, water in the reservoir mimics the sound of moving water, which makes the indoor rowing experience more lifelike. Built to Endure While Building Endurance: The Wave Water Rowing Machine is built to last no matter how often you use it. With steel frame construction and rowing beam, the rower can withstand years of prolonged, intense use. Even more, the sturdy, pivoting footplates with straps keep you secure during your workout while the rower itself is stabilized on leveling endcaps with dials. To further motivate you, the rower also comes equipped with a multi-function monitor that tracks dis
As previously discussed, the rowing machine’s big advantage is that it provides more than just a cardio workout. It can definitely help you build muscle and lose weight. Compared to a treadmill, the rowing machine works most of your body. It will really hit your shoulders, core, quads, hamstrings, glutes, arms and back effectively while being low impact thus reducing the stress on your joints. Bigger muscles need more energy and will burn fat to get it, which of course leads to healthy weight loss.
