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.
The oldest, and arguably most famous, head race is the Head of the River Race, founded by Steve Fairbairn in 1926 which takes place each March on the river Thames in London, United Kingdom. Head racing was exported to the United States in the 1950s, and the Head of the Charles Regatta held each October on the Charles River in Boston, Massachusetts, United States is now the largest rowing event in the world. The Head of the Charles, along with the Head of the Schuylkill in Philadelphia and the Head of the Connecticut, are considered to be the three “fall classics.”[40]

 The amount of water in the tank simulates the weight of the boat and crew, the more water in the tank the heavier the boat and crew. The standard Calibration Level is Level 17. If the user is lighter in weight, Level 15-16 can be used. If the user is heavier in weight, level 18-19 can be used. The maximum level to fill the tank is Level 19. DO NOT fill above the maximum level – this could void the warranty.
Bring the experience and benefits of rowing on water with this professionally-built Stamina water rower machine. The incorporated water resistance in this exercise machine offers smoother and more consistent rowing but more importantly, just like rowing in an actual body of water, this workout machine is built to provide infinite resistance--harder and faster rowing motions cause increased resistance. To tailor the resistance according to your fitness goals, simply increase or decrease water level using the siphon included in the package. Moreover, the steel frame construction and rowing beam ensure durability for years while the sturdy, pivoting footplates with straps offer comfort and security. To help you keep track of your fitness progress, this home gym machine is also equipped with a multi-function monitor that tracks total strokes, strokes per minute, distance, time, and calories burned. Other features include: wide molded seat, textured and padded handles for better and comfort
Con's: Super bummed that for $1160 they couldn't include an internal ANT+ transponder and Heart Rate strap(sub $100 package). The foot straps are crap! Within the first 1000m of moderate rowing they loosen to the point of being able to pull foot out on Recovery of stroke(Yes, even with ball of foot down). I really wish the WaterCoach F.I.T. software for the S4 Monitor was macOS compatible. It'd be nice to able to customer program workouts on my MacBook Pro or iMac.

This piece of finely tuned, hand-crafted, water-resistance workout equipment also sits at the top end of the rowing machine spectrum. Employing a water flywheel that helps to mimic the feel of rowing in actual water, the natural wood WaterRower Rowing Machine will bring you a smooth, yet challenging workout that is as tough as you want it to be. If rowing is one of the best exercises you can do for your body as far as natural motion with low to no-impact, then the WaterRower is one of the best machines to do it on.
The rowing machine itself is unlike any other on the market with its patented water filled flywheel. It is hard to exactly copy the action of a scull on the water, but the mechanics of the flywheel spinning in water comes in a close second on dry land. The fact that the water is 800 times denser than air means that there is no need for any extra resistance or dampening that you will find in normal air rowers. The faster you pull, the more resistance is generated giving it infinite variability. However, if you want to be able to practice rowing with a faster stroke, you will have to reduce the amount of water in the tank unlike an air rower where you just have to adjust the baffle.
