Walk into any sporting goods store and you'll find rowing machines with three different resistance types: air, magnetic, and water. (Hydraulic still exists too, but it's basically a glorified spring mechanism — skip it.)
The resistance type matters more than brand name, screen size, or any other spec on the box. It determines how the stroke feels, how loud the machine is, and ultimately whether you'll still be using it six months from now. Most people get this wrong because they shop by price or by how pretty the machine looks in the ad. Then they're surprised when the experience doesn't match what they expected.
Air rowers use a fan flywheel. When you pull the handle, the fan spins and displaces air, creating resistance. The harder you pull, the more air the fan has to move, and the more resistance you feel. This is called variable resistance — it scales infinitely with your effort.
How it feels: The closest thing to rowing on actual water. The resistance builds naturally through the stroke, with a slight "whoosh" that becomes rhythmic and almost meditative during longer sessions. There's a damper setting (typically 1-10) that adjusts the airflow — this changes the feel of the stroke but doesn't set a fixed resistance level. Damper 4-5 simulates a racing shell on water. Damper 10 simulates rowing a heavy barge.
Who it's for: Anyone serious about rowing as exercise. Air rowers are what Olympic athletes train on, what CrossFit gyms use, and what every major rowing competition in the world standardizes on. If you want data that means something — where your 2K split time is directly comparable to anyone else's in the world — you need an air rower.
The downside: Noise. Air rowers are the loudest type. The fan generates a constant whooshing sound that ranges from moderate (around 60 dB at easy effort) to genuinely loud (72+ dB at high intensity). That's louder than a normal conversation. If you live in an apartment with thin walls or row at 5am with sleeping family members, this is a real problem.
Notable machines: The Concept2 RowErg ($990) is the undisputed standard. The Rogue Echo Rower ($895) is a newer competitor with nearly identical performance and the official CrossFit rower. Both are built to survive decades of daily use.
Durability: Exceptional. Air rowers are mechanically simple — a fan, a chain or belt, a sliding seat. There's very little to break. Concept2 machines from the 1990s are still running fine with minimal maintenance (wipe the rail, oil the chain monthly).
Magnetic rowers use magnets positioned near a flywheel. Adjusting the resistance moves the magnets closer or further from the wheel, increasing or decreasing the magnetic field's braking effect. Most have 8-32 levels selected by a dial or electronically.
How it feels: Smooth and consistent at each level — you set it to level 5, and every stroke at level 5 feels the same regardless of how hard you pull. This is fundamentally different from air and water, where resistance increases with effort. Some people prefer this predictability. Others find it feels "dead" compared to dynamic resistance.
Higher-end magnetic rowers (like the Hydrow Wave's electromagnetic system) use computer-controlled magnets that can simulate variable resistance more convincingly. But most budget magnetic rowers under $500 feel distinctly mechanical — you can sometimes feel the magnets "click" between levels.
Who it's for: Apartment dwellers, people who need silence, and anyone who prioritizes convenience over training fidelity. Magnetic rowers are typically the quietest (42-50 dB), most compact, and easiest to fold and store. They're also the most common type under $500.
The downside: The fixed resistance doesn't scale with effort. This means experienced users can "rip through" the resistance at lower settings — you pull hard, and the machine can't push back proportionally. This limits the training ceiling. Budget magnetic rowers also tend to have shorter rail lengths, lower weight capacities, and less precise data tracking.
Many magnetic rowers also lack data connectivity. Without Bluetooth FTMS, your workout data stays locked in whatever proprietary app the manufacturer provides (or doesn't provide). If you care about tracking workouts in Strava or Garmin Connect, check connectivity before buying.
Notable machines: The Hydrow Wave ($1,695 + $44/month) is the premium option with electromagnetic resistance that genuinely feels fluid. The NordicTrack RW900 (~$1,600 + iFIT subscription) auto-adjusts resistance during guided workouts. The Sunny Health SF-RW5515 (~$260) is the budget king — quiet, foldable, and functional, though limited in resistance range and data.
Durability: Varies wildly by price. Budget magnetic rowers ($200-400) typically last 1-3 years under regular use, with common failure points being the tension belt, footstraps, and display electronics. Premium magnetic rowers ($1,500+) are better built but still don't match the decades-long lifespan of quality air rowers.
Water rowers use a tank filled with water and paddle-like blades. When you pull, the blades spin through the water, creating resistance. Like air, the resistance is variable — pull harder, move more water, feel more resistance.
How it feels: The most realistic rowing experience available indoors. The resistance curve mimics actual water perfectly because, well, it is actual water. The sound is also the most pleasant — a soft, rhythmic swooshing that many people describe as calming. If you've ever been in a wooden boat on a lake, this is the closest you'll get in your living room.
Who it's for: People who want an aesthetically beautiful machine with a natural feel. Water rowers, especially those with wooden frames (WaterRower, Ergatta), look like furniture rather than gym equipment. They're conversation pieces. They're also quieter than air rowers, though louder than magnetic — roughly 55-60 dB.
The downside: Maintenance. The water tank needs to stay clean — purifying tablets every 3-6 months at minimum. Some users report algae growth if neglected. Leaking is a possibility, especially with cheaper models. And water rowers are heavy — 75-100+ lbs when filled — and typically don't fold. They also can't produce performance data that's comparable across brands the way air rowers (specifically Concept2) can.
Price is another factor. Quality water rowers start around $700-800 and go up to $2,000+ for premium models with connected screens. The Ergatta ($2,200+) adds gamified programming that makes workouts genuinely engaging, but the subscription adds ongoing cost.
Notable machines: The WaterRower Natural ($1,199) is the classic — beautiful ash wood frame, minimal design. The Ergatta ($2,200 + $29/month) adds a 17" touchscreen with gamified programming to a WaterRower base. The Merach Water Rower (~$460) is a budget option with decent reviews but limited long-term data.
Durability: Good for the mechanical components (water tank and paddles are simple), but the wooden frames require more care than steel. Keep water rowers indoors, away from extreme temperature changes, and maintain the water quality. The electronic components (screens, Bluetooth) are the most likely failure points.

If you want the best training tool and don't care about noise, get an air rower. The Concept2 at $990 with no subscription is probably the best value in fitness equipment, full stop. It's what every gym uses for a reason.
If you live in an apartment or need silence, magnetic is your only realistic option. The Hydrow Wave is the best one we've used, but it costs $1,700 plus a monthly subscription. The Sunny SF-RW5515 is fine for getting started at $260, but you'll outgrow it. Most budget magnetic rowers are disposable — plan accordingly.
If aesthetics genuinely matter and the machine will live in your living room permanently, water rowers are beautiful objects that also happen to give you a great workout. Don't go cheap though. A $500 water rower will leak and disappoint you. The WaterRower Natural at $1,200 or the Ergatta at $2,200 are where water rowers start being worth it.
There are also hybrid machines now — the Rogue Echo and Aviron Strong combine air and magnetic — but they're niche.
One last thing: if you can, try all three types at a gym before buying. Reading about resistance types is one thing. Feeling the difference between pulling against air, magnets, and water is another. That ten-minute test will tell you more than any article (including this one).
