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 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.

The standard length races for the Olympics and the World Rowing Championships is 2 kilometres (1.24 mi) long; 1.5 kilometres (0.93 mi) - 2 kilometres (1.24 mi) for US high school races on the east coast; and 1,000 m for masters rowers (rowers older than 27). However the race distance can and does vary from dashes or sprints, which may be 500 metres (1,640 ft) long, to races of marathon or ultra-marathon length races such as the Tour du Léman in Geneva, Switzerland which is 160 kilometres (99 mi),[36] and the 2 day, 185-kilometre (115 mi) Corvallis to Portland Regatta[37] held in Oregon, USA. In the UK, regattas are generally between 500 metres (1,640 ft) and 2 kilometres (1.24 mi) long.
With magnetic rowing machines, adjusting the resistance means varying the distance between a flywheel and one or more strong magnets. This is done either manually, using mechanical sliders, or digitally by the console controls. Like hydraulic rowers, magnetic rowing machines operate quietly and have a compact design for easy storage. Unlike hydraulic rowers, they can provide a smooth and consistent workout. It's a very different kind of feel to what you'd expect from an air or water rower, though. You still get a good workout, but it doesn't simulate the sensation of rowing in quite the same way.

Indoor rowing machines have come a long way and there are now a variety of sleek, highly-refined pieces of exercise equipment ready to get your cardio health on the upswing. Having a rower right there in your home can really be the push you need to get your muscles moving in a challenging yet comfortable way. Overall, rowing machines provide an outstanding way to increase fitness by burning calories and building muscle in a safe, low-impact way.
The WaterRower Classic Rower is unsurpassed in terms of design refinement. WaterRower Classic Rower has a patented WaterFlywheel design emulates rowing like no machine before it. Smooth, silent and storing conveniently upright the WaterRower Classic Rower is perfect for any user and in any environment. The WaterRower Classic Rower has an unique patented WaterFlywheel has been designed to emulate the dynamics of a boat moving through water.

The WaterRower Natural is outfitted with a Series 4 performance monitor that's designed to balance technical sophistication with user-friendliness. The monitor--which includes six information and programming windows, six QuickSelection buttons, and three navigation buttons--displays your workout intensity, stroke rate, heart rate, zone bar, duration, and distance. Plus, the monitor is compatible with an optional heart rate chest strap and receiver, which helps you optimize your workout and achieve your exercise objectives.
The meter didn't work properly. It wasn't keeping the distance - we would row for 30 mins and wouldn't even be at 1km!!! And the strokes per minute was reading double strokes (which the company said was normal - huh?). Their customer service team was good and tried to make it work but we ended up returning it and spent the extra money to get a WaterRower and it is amazing!!!
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.

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.

The horizontal movement of the water when a wave passes is approximately equal to the up and down movement of the water. If you are on flat water and are parallel to waves made by a passing boat, your boat will move side-to-side as much as up-and–down as the wave passes under you. The side-to-side movement actually creates most of the difficulty in balancing the boat in such a situation. However, under typical conditions in the bay there can be such varied wave action that you can’t easily distinguish horizontal and vertical motion.

At the collegiate level (in the United States), the lightweight weight requirements can be different depending on competitive season. For fall regattas (typically head races), the lightweight cutoff for men is 165.0 lb. and 135.0 lb. for women. In the spring season (typically sprint races), the lightweight cutoff for men is 160.0 lb., with a boat average of 155.0 lb. for the crew; for women, the lightweight cutoff is 130.0 lb.[48]
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.
