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.
Rowing events use a systematic nomenclature for the naming of events, so that age, gender, ability and size of boat can all be expressed in a few numbers and letters. The first letter to be used is 'L' or 'Lt' for lightweight. If absent then the crew is open weight. This can be followed by either a 'J' or 'B' to signify junior (under 19 years) or under 23 years respectively. If absent the crew is open age (the letter 'O' is sometimes used). Next is either an 'M' or 'W' to signify if the crew are men or women. Then there is a number to show how many athletes are in the boat (1,2,4 or 8). An 'x' following the number indicates a sculling boat. Finally either a + or – is added to indicate whether the boat is coxed or coxswainless.
In sweep or sweep-oar rowing, each rower has one oar, held with both hands. This is generally done in pairs, fours, and eights. In some regions of the world, each rower in a sweep boat is referred to either as port or starboard, depending on which side of the boat the rower's oar extends to. In other regions, the port side is referred to as stroke side, and the starboard side as bow side; this applies even if the stroke oarsman is rowing on bow side and/or the bow oarsman on stroke side.

Ergometer rowing machines (colloquially ergs or ergo) simulate the rowing action and provide a means of training on land when waterborne training is restricted, and of measuring rowing fitness. Ergometers do not simulate the lateral balance challenges, the exact resistance of water, or the exact motions of true rowing including the sweep of the oar handles. For that reason ergometer scores are generally not used as the sole selection criterion for crews (colloquially "ergs don't float"), and technique training is limited to the basic body position and movements. However, this action can still allow a comparable workout to those experienced on the water.

The advantages with air rowers is that there is smooth action; there is only small wear and tear to its mechanism; its automatic feature adjusts according to your rate of strokes; and there is a wide range of the resistance readily available in replicating the feel of rowing through the waters. The only disadvantage of this machine is that it tends to be noise indoors.
In the starting position, the knees should be bent, with the shoulders and arms extended forward and the shins held vertically. Begin rowing by pushing both feet against the row machine’s platform and straighten the legs until they’re slightly bent. Pull the paddle towards you, using bent elbows as you slightly lean back while focusing on keeping your back straight. This type of motion should be both continuous and fluid.
This affordable rowing machine is streamlined, simple to use, built well, has a comfy seat with a realistic rowing movement, and especially good for a newbie. Because the cost of this machine is less than $150, it is popular on the net. As it has a hydraulic rower, resistance is provided by just one piston under the main key column. Along with a comfy cushioned seat, LCD screen, this machine provides 12 hydraulic cylinder resistances.
