Although the oar can be conveniently thought of as a lever with a "fixed" pivot point in the water, the blade moves sideways and sternwards through the water, so that the magnitude of the propulsion force developed is the result of a complex interaction between unsteady fluid mechanics (the water flow around the blade) and solid mechanics and dynamics (the handle force applied to the oar, the oar's inertia and bending characteristic, the acceleration of the boat and so on).
A 125-pound person moving at an average pace for 30 minutes on a treadmill will burn roughly 250 calories. However, they aren’t able to take advantage of this after-burn effect. The same person rowing vigorously will burn around to 250 calories but will have less stress placed upon their joints and continue to burn calories after the workout has ended. Rowing machines have been shown to burn on average 800 calories an hour if you work harder and are slightly heavier.

This type of calorie burn is better than what you would get from cycling or running, and it’s much gentler on the body. You can also position your hands differently in order to work new muscle groups in your lower and upper arms. Many people will be surprised to learn that rowing works the legs more than any other muscle group, but by switching up your rowing position, you can also focus on your abs, arms and shoulders for a total upper body workout that can provide impressive results just by working out a few times a week.
For a third option, you can look to hydraulic machines, which use pistons to generate resistance. Hydraulic rowers are quiet, and they also tend to be smaller and cheaper than other kinds of rowing machines, but you won’t get the same smooth rowing feel, or the consistency of resistance, that you would get with an air or water rower. What's more, reviewer after reviewer has found them unreliable and high-maintenance.
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.

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!!!
