The table on the left gives the speed of waves of different wave lengths in deep water. “Deep” in this context is not an absolute value, but is relative to wave length. The simple relationship starts to to breakdown when the depth of the water is less than 1/4 th the wave length. At that depth the bottom exerts sufficient drag on the wave to slow its motion and thus decrease the wavelength [equations and more about wave speed].
The Challenge AR has the capability to allow the rower to control and adjust the resistance from “Feather light” to “Olympic sprint” delivering a silky smooth resistance to the user’s effort and instantaneous response to input with no “flat sport”.  With water resistance being the most accurate manner in which to simulate actual outdoor rowing, the Challenge AR provides a smooth and consistent sensation throughout the range of motion of the exercise experience.  
Water machines are generally quieter than air rowers - you can still hear the water moving in the tank, but users tend to find this a pleasant ambient noise. Water rowers also tend to require little maintenance. Because there's a tank full of water involved, however, these can be very heavy, and larger than most other rowers: if you have a smaller home, a less-than-permanent workout space, or you move frequently, these might not be best for you. And because they're so high-performing, they do come at a high cost.
As with any fitness activity, it’s important to exercise with proper technique, however. The big muscles in the legs are where most of the workout action should be. Injury to the lower back can occur from bending too far forward in the row. It’s best to maintain a upright 90 degree angle to the rowing machine’s seat and slider bar. Using the legs for the motion rather than relying as heavily on the back or arms can help reduce the chance of muscle pulls or other related injuries. Always check with a physician before starting any new fitness regimen.
1.) I keep reading about cracks and leaks that develop in the water tank. WaterRower even offers a tank repair kit for this very issue. It seems to me that this is a design flaw that they refuse to address, instead offering a fix for when it eventually occurs. Have you seen these tanks to eventually leak? I’m surprised they haven’t tried a one-piece tank.
Whilst the action of rowing and equipment used remains fairly consistent throughout the world, there are many different types of competition. These include endurance races, time trials, stake racing, bumps racing, and the side-by-side format used in the Olympic games. The many different formats are a result of the long history of the sport, its development in different regions of the world, and specific local requirements and restrictions.
Using the same principles that govern the dynamics of a boat in water, the WaterRower S1 Stainless Steel Rower with S4 Monitor provides an unlimited range of resistance making it suitable for a variety of strength and skill levels. In a boat, the faster you move, the greater the drag and the greater the intensity of exercise required to maintain your speed. The limit to the speed you can maintain is you, your physiology, not the machine. For maximum realism and comfort, the WaterRower S1 Stainless Steel Rower's precision spragg clutch engages the instant the handle is pulled, so there is no jerkiness or jarring at the beginning of the stroke. The WaterRower S1 Stainless Steel Rower with S4 Monitor leaves you with the distinct sense that you are gliding effortlessly across the water.

As I mentioned, the rowing experience with the WaterRower is amazing. I bought the rower for myself, but my wife was curious and decided to try it out. She loves it, and now rows almost daily. We have a treadmill that neither of us has used since we started rowing - the WaterRower is a much better workout and much more enjoyable at the same time. It's easy to adjust the intensity, pace and duration of your exercise. There is nothing to change on the rower (* see note below), you just row harder or faster, adjust how far you lean forward and back during your stroke. The WaterRower will keep up with you as your fitness increases, all you need to do is keep throwing more and more at it.

Unlike the 1445, the Elite Wave Water Rowing Machine includes an upgraded, high-end fitness monitor and a chest strap heart rate sensor. Programmed to sync seamlessly with the multi-function monitor, the data the sensor provides allows you to tailor your workout. For example, you can target a certain heart rate for weight loss or to increase endurance by adjusting your rowing speed and therefore, your rowing intensity. In addition to pulse, the multi-function monitor also tracks distance, time, calories burned, stroke count and strokes per minute to further motivate you during your rowing session. For further customization, users can also add or remove water using the included siphon to either increase or decrease the resistance.

Because of the vast array of products that might contain one of the chemicals or ingredients on the list, we must include Proposition 65 warnings in our communications with you.

I used it a few more times. The strap became more frayed in different areas. While packaging it to return I noticed there is a bungy cord underneath. The cord is already showing stretch/premature wear. This was designed poorly. I've since purchased a concept2 rower. I've found that the computer on the stamina was way off on its stroke count. It appears to have been doubling the stroke count compare to my concept2.

Rowing whether competitive and recreational is unique compared to most sports because this type of aerobic exercise gives all your major muscle groups a beneficial workout. Everything from your legs, back, and arms are engaged while rowing. This is a low-impact sport, the rowing stroke is a fairly safe motion, providing little room for the serious injury often found in contact and high-impact sports.
If you’re new to rowing, start off slow and begin with a five to ten-minute warm-up, followed by a twenty-minute workout and five to ten additional minutes for the cool down. During your workout, if you continue to consistently row at the same speed, over a period of a few sessions you should begin to notice an increase in your endurance. For a more intense workout, you can try interval training with your rower. Start off each workout by rowing for five to ten minutes at the highest resistance level, as fast as you can. Next, for two to three minutes row slowly, at the lowest resistance setting. Do this for thirty to sixty minutes. Interval training has been incorporated in many different types of exercise from cardio to strength training, and it’s designed to give your metabolism a jolt and make your body improve its fat burning abilities
WaterRower Rowing Machines offer a pleasant rowing exercise while holding true to the dynamics of on-water rowing; burn up to 1000 calories an hour and work up to 84 percent of your muscle mass! Rowing provides an effective, high-intensity, cardio workout, while maintaining a low-impact to the joints. Workout at your own pace as the WaterFlyWheel's self-regulating resistance dynamically adjusts to each of your strokes. Unlike common ergometers, to change resistance on a WaterRower rowing machine you simply row harder!

On theme with C2’s interchangeability, models D or E are essentially the same machine. When we talk about one we’re talking about both. The Concept 2 E is just 8 pounds heavier but is made out of stronger stuff all around — what’s plastic on the model D is aluminium on the model E, and what’s aluminum on the model D is welded steel on the model E. The only noticeable variations are seat height and display position.

The International Rowing Federation (French: Fédération Internationale des Sociétés d'Aviron, abbreviated FISA), responsible for international governance of rowing, was founded in 1892 to provide regulation at a time when the sport was gaining popularity. Across six continents, 150 countries now have rowing federations that participate in the sport.[3]
Noise level is another large factor that tips the scale more towards water rowers. Air rowers make a fairly loud “whooshing” noise every stroke, which makes them bad for people who like watching TV, have sleeping children, live in apartments, or like working out early in the AM. Water rowers do make some noise but the splashing of water in the tank is a lot quieter and more soothing than the fan noise produced by air rowers.
Rowing is a low impact sport with movement only in defined ranges, so twist and sprain injuries are rare. However, the repetitive rowing action can put strain on knee joints, the spine and the tendons of the forearm, and inflammation of these are the most common rowing injuries. [9]If one rows with poor technique, especially rowing with a curved rather than straight back, other injuries may surface, including back pains. Blisters occur for almost all rowers, especially in the beginning of one's rowing career, as every stroke puts pressure on the hands, though rowing frequently tends to harden hands and generate protective calluses. Holding the oars too tightly or making adjustments to technique may cause recurring or new blisters, as it is common to feather the blade (previously described). Another common injury is getting "track bites", thin cuts on the back of one's calf or thigh caused by contact with the seat tracks at either end of the stroke.
Rowing is one of the few non-weight bearing sports that exercises all the major muscle groups, including quads, biceps, triceps, lats, glutes and abdominal muscles. The sport also improves cardiovascular endurance and muscular strength. High-performance rowers tend to be tall and muscular: although extra weight does increase the drag on the boat, the larger athletes' increased power tends to be more significant. The increased power is achieved through increased length of leverage on the oar through longer limbs of the athlete. In multi-person boats (2,4, or 8), the lightest person typically rows in the bow seat at the front of the boat.

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.
Now back to the aesthetics, this version of WaterRower’s natural wood line of rowers comes in beautiful Black Walnut, which the company chose for its superior sound and vibration absorption. It’s hand-made in the USA and comes with excellent warranties and customer service. Overall, WaterRower is known for the quality of their rowing machines and the Classic is no exception.  And if you do want to get this rower just as an attractive conversation piece, it easily stores upright against a wall.  That said, we strongly recommend using The WaterRower Classic Rowing Machine for fitness, not just eye-candy.
Velocity Exercise puts a premium on comfort here with a polyurethane molded saddle seat, and magnetic drum resistance contributes to a row machine that is durable, won’t need much or any maintenance, and, as we mentioned does not create much noise in use. This makes it easy to row while watching TV or listening to music. It also means the other people in your home won’t be listening to you workout quite as much. Easy to assemble and store, the Velocity Exercise Magnetic Rower CHR-2001 is a good choice for a mid-priced rower.  Click here to read the full review.
There is some minor maintenance. Because it's made out of wood, which can expand and contract, the bolts need tightening every few months or so. It's easy and takes only a couple of minutes. That, and putting in a fresh water purification tablet every six to twelve months, are about it for regular maintenance. The only problem I've had with the rower (the reason for 4 stars instead of 5) was a squeak that developed after about 6 weeks. It took me some time to determine the source of the squeak, which was a metal bracket connecting the footrest board to the horizontal boards above the drum. I had to partially disassemble the top section and tighten four bolts, but that fixed the problem and it's been quiet ever since.

Heavyweight rowers of both sexes tend to be very tall, broad-shouldered, have long arms and legs as well as tremendous cardiovascular capacity and low body fat ratios. Olympic or International level heavyweight male oarsmen are typically anywhere between 190 cm and 206 cm (6'3" to 6'9") tall with most being around 198 cm (6'6") and weighing approximately 102 kg (225 lb) with about 6 to 7% body fat.

When feet are in position and you are seated, ensure you are sitting in a tall yet relaxed position. Try to feel as if you are sitting on your ‘sit’ or ischia bones and rock slightly forwards and backwards on these bones. Your body weight will move from the front to the back of the seat. Ensure you are sitting with a locked core, shoulders relaxed and head looking forwards.
Rowers may take part in the sport for their leisure or they may row competitively. There are different types of competition in the sport of rowing. In the U.S. all types of races are referred to as regattas whereas this term is only used in the UK for head-to-head or multi-lane races (such as those that take place at Dorney Lake), which generally take place in the summer season. Time trials occur in the UK during the winter, and are referred to as Head races. In the US, head races (usually about 5k, depending on the body of water) are rowed in the fall, while 2k sprint races are rowed in the spring and summer.
Performance is meaningless if you can’t or don’t want to use the equipment, and that’s why the Wave Water rower was built for comfort and convenience. With a wide, molded seat to accommodate users of all sizes and a padded, textured rowing handle, you can build your strength and endurance in ease. When setting up the rower, the leveling endcaps with a dial ensure stability. After your workout, storing your Wave Water rower is easy – just fold the frame and roll the rower into a closet or corner.
Unlike the 1445, the Elite Wave Water Rowing Machine includes an upgraded, high-end fitness monitor and a chest strap heart rate sensor. Programmed to sync seamlessly with the multi-function monitor, the data the sensor provides allows you to tailor your workout. For example, you can target a certain heart rate for weight loss or to increase endurance by adjusting your rowing speed and therefore, your rowing intensity. In addition to pulse, the multi-function monitor also tracks distance, time, calories burned, stroke count and strokes per minute to further motivate you during your rowing session. For further customization, users can also add or remove water using the included siphon to either increase or decrease the resistance.

Amateur competition in England began towards the end of the 18th century. Documentary evidence from this period is sparse, but it is known that the Monarch Boat Club of Eton College and the Isis Club of Westminster School were both in existence in the 1790s. The Star Club and Arrow Club in London for gentlemen amateurs were also in existence before 1800. At the University of Oxford bumping races were first organised in 1815 when Brasenose College and Jesus College boat clubs had the first annual race[14] while at Cambridge the first recorded races were in 1827.[15] Brasenose beat Jesus to win Oxford University's first Head of the River; the two clubs claim to be the oldest established boat clubs in the world. The Boat Race between Oxford University and Cambridge University first took place in 1829, and was the second intercollegiate sporting event (following the first Varsity Cricket Match by 2 years). The interest in the first Boat Race and subsequent matches led the town of Henley-on-Thames to begin hosting an annual regatta in 1839.[16]


The WaterRower Club is hand crafted in solid Ash and stained for color. The WaterRower Club has been designed for High Traffic Areas such as Commercial Gyms, Studios, Rehabilitation Clinics, etc. Its Black Rails have been styled to prevent scuffing, other wooden components are finished in an attractive rosewood which is more resistant to soiling than the Natural model.
