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.

Originally made from wood, shells are now almost always made from a composite material (usually a double skin of carbon-fibre reinforced plastic with a sandwich of honeycomb material) for strength and weight advantages. FISA rules specify minimum weights for each class of boat so that no individual team will gain a great advantage from the use of expensive materials or technology.

However, I own an air rower and have zero worries about maxing out it’s ability. I can completely exhaust myself on any type of workout. Air and water rowers are the chosen resistance type by Olympic athletes and any athlete looking to train their full-body cardio. I don’t think they would choose this resistance type if they felt they could max it out.

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.

The WaterRower Oxbridge is hand crafted in solid Cherrywood. Like all woods, Cherrywood may vary in color from a red-brown to deep... red. The wood will darken in color with exposure to light. For this reason all WaterRower Cherrywood components are kept in light free rooms to protect from shadowing. A new WaterRower Oxbridge will therefore appear quite light in color. The wood will however darken over time reaching a rich reddish hue.Handcrafted rowing machine with inchwater flywheel inch that replicates actual rowing feelFlywheel sits in enclosed water tank to provide smooth, quiet, self-regulated resistanceSeries 4 performance monitor tracks workout intensity, stroke rate, heart rate, and moreStores upright; measures 84 x 21 x 22 inches (W x H x D) and weighs 117 poundsStores upright; measures 84 x 21 x 22 inches (W x H x D) and weighs 117 pounds read more
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.
