One of the underrated advantages of treadmills and bikes is that they attempt to replicate something with which most people are already familiar—walking, running, or biking. The barriers to entry are low, and the task of planning and completing a workout is a little more intuitive, since most people know what those activities feel like. Those heuristics are out the door with a rowing machine, though. Do you just... pull? How far? How hard? And why does it insist on measuring distance in meters? We asked Caley Crawford, the Director of Education at Row House, for tips on getting started so that, hopefully, your experience doesn't end with you throwing your hands up in frustration and crawling back to the elliptical room.
Rowing machines are equipped with a device called the damper, which is often pushed all the way up to 10 in gyms. Higher damper levels don't affect resistance, though—they just increase the drag. (Crawford likens it to stacking bricks in your boat). Try moving it down to somewhere between 3 and 5, she says, and focusing on maintaining that explosiveness, which is the key to propelling you farther in a given period of time.
Adaptive rowing is a special category of races for those with physical disabilities. Under FISA rules there are 5 boat classes for adaptive rowers; mixed (2 men and 2 women plus cox) LTA (Legs, Trunk, Arms), mixed intellectual disability (2 men and 2 women plus cox) LTA (Legs, Trunk, Arms), mixed (1 man and 1 woman) TA (Trunk and Arms), and men's and women's AS (Arms and Shoulders). Events are held at the World Rowing Championships and were also held at the 2008 Summer Paralympics.[59]
The “drive” describes the basic sequence of the rowing stroke, which is legs first, then back, and finally arms. A few common mistakes to avoid are pulling with your arms first or opening up with your shoulders before you’ve driven the legs down. “I always liken the movement to a power clean and stress the importance of holding a strong body angle while pushing the legs down and then accelerating through with the body and then arms,” says Frandsen. 
One of the major deciding factors between water and air rowers is price. Water rowing machines are often found in higher price ranges with the lowest model going for $700 and the best models starting around $1,100. Air rowers are found in every price range starting at $300 and going as high as $1,000+. The affordability of air rowing machines makes them very popular.
