Air vs Magnetic vs Water Rowing Machines: Pick the Right Resistance

A rowing machine is one of the most underrated pieces of home cardio equipment. It is full-body work, low-impact, scalable in intensity, and surprisingly compact for the workout it delivers. The piece most people get wrong when buying one is the resistance type. Air, magnetic, and water rowers feel completely different in use, sound different in a home, and last very different lengths of time. Choosing the wrong resistance type is the most common reason people give up on rowing after a few months.

There is no universally best resistance. There is a best fit for your apartment, your training goals, and your tolerance for noise.

How air rowing actually works

Air rowers use a flywheel inside a cage. As you pull the handle, a chain spins the flywheel and the fan blades push air. The faster you pull, the more air the fan moves, and the more resistance you feel. Air resistance is dynamic. The harder you pull, the harder it pushes back.

This means an air rower has effectively no upper limit on resistance. Pulling harder produces more force, more or less indefinitely. The Concept2 RowErg is the canonical example. Damper settings on an air rower (the 1-to-10 lever on the side) do not change the resistance directly. They change how much air the flywheel takes in per stroke, which shifts the feel from “lighter and quicker, like a racing shell” to “heavier and slower, like a fishing boat.” Most experienced rowers train at damper 3 to 5, not 10.

Air rowers are loud. The whoosh of the flywheel scales directly with effort. At competition pace, a Concept2 in a small room is loud enough that you cannot have a conversation comfortably. In an apartment with thin walls, this is a real problem.

Durability is the strongest argument for air. Concept2 RowErgs last for decades. Many gyms still use machines from the late 1990s without major service. The mechanism is simple, parts are cheap, and Concept2 still services every model they ever made.

How magnetic rowing works

Magnetic rowers use a flywheel that passes through a magnetic field. The strength of the field is adjustable, usually with a dial that controls how far the magnets sit from the flywheel. Closer magnets create more drag, lighter magnets create less.

Magnetic resistance is constant within a given setting. Whether you pull lightly or aggressively, the resistance per stroke is the same. This is different from air or water rowers and feels mechanical to experienced rowers. The advantage is that you can dial in a specific resistance level and know it will feel the same on every stroke.

Magnetic rowers are quiet, often under 35 dB during use. The flywheel does not push air, so there is no whoosh. The chain or strap and the seat sliding are the loudest parts of the machine, and both are quiet. In an apartment, a magnetic rower is usually the most considerate option.

The trade-off is the rowing feel. Magnetic feels less like a boat than air or water. The dynamic build of resistance during the drive that makes rowing satisfying is absent. Mid-range magnetic rowers ($300 to $700) tend to feel notably more mechanical than higher-end air or water rowers. The Hydrow uses electromagnetic resistance that simulates dynamic feel more closely and is one of the better magnetic implementations, but it costs significantly more than basic magnetic rowers.

Durability of magnetic rowers varies widely. Quality builds (Hydrow, NordicTrack RW900) last 10 to 15 years. Cheaper models often fail at the seat rollers or the chain after a few years.

How water rowing works

Water rowers use a flywheel with paddles inside a tank of water. Pulling the handle spins the flywheel, which spins the paddles, which push water. The resistance is dynamic like an air rower. Harder pulls produce more resistance.

The defining feature of a water rower is the feel. The water-driven flywheel produces a smooth, building resistance through the stroke that mimics rowing in an actual boat more closely than any other indoor rowing technology. Many serious rowers prefer water rowers specifically for this feel.

Water rowers are also one of the most attractive pieces of home gym equipment. The WaterRower in particular looks like furniture, with wooden frames and visible water in the tank. Some users keep them in living rooms rather than basements or garages, which improves the likelihood they actually get used.

Sound is moderate. The water swish is quieter than an air rower’s whoosh but louder than a magnetic rower’s near-silence. Most users describe it as soothing rather than annoying.

Resistance adjustment on a water rower comes from the amount of water in the tank, not a dial. Adding water makes the rower heavier. Removing water makes it lighter. This is a more permanent adjustment than air or magnetic damping, and most users set it once and leave it.

Durability is strong. WaterRowers commonly last 15 to 20 years. The main failure point is the bungee cord (which retracts the handle) that wears out every few years and is easy to replace.

How sound matters for home use

Apartment or shared housing: magnetic first, water second. Air rowers are rarely appropriate for shared walls unless you can train when neighbors are out.

House with basement or garage gym: any resistance type. Air rowers are fine because the sound stays contained.

Living room or multipurpose space: water rower if aesthetics matter, magnetic if pure quietness matters.

Garage or outdoor space: air or magnetic. Water rowers do not love freezing temperatures because water in the tank can expand.

Footprint and storage

Concept2 RowErg: 96 inches long during use. Separates into two pieces for vertical storage in about a 25-inch by 28-inch space.

WaterRower: 84 inches long during use. Stands vertically on end for storage in about a 22-inch by 22-inch footprint, with water still in the tank.

Magnetic rowers (typical): 70 to 90 inches long during use. Most fold partially or fully for storage. Hydrow does not fold and takes its full 86-inch length.

For a small apartment, the WaterRower’s vertical storage is usually the most space-efficient because it stands without dismantling. For long-term use, the Concept2 is also compact when broken down.

Software, classes, and connected features

Concept2: minimal software. The PM5 monitor is excellent for data but is not a screen for classes. Pairs with apps like ErgZone or Asensei.

Hydrow: screen-based class platform similar to Peloton. Strong production values. Requires a monthly subscription.

WaterRower: bare-bones built-in monitor. The Smart Row attachment adds connectivity for class apps.

NordicTrack RW900: built-in screen with iFit classes. Requires monthly subscription.

Cheap magnetic rowers: usually a basic monitor and no app integration.

For users who need motivation from instructor-led classes, Hydrow or NordicTrack are the obvious picks. For users who train independently and want data, Concept2 is the gold standard. For users who care about feel and aesthetics, WaterRower stands alone.

A practical pick by use case

Serious indoor rowing training, competition prep, or CrossFit: Concept2 RowErg, no contest. It is the standard and the data is comparable across machines.

Apartment cardio with mixed family use: magnetic rower with a screen and class subscription (Hydrow or NordicTrack RW900). Quiet, motivating, and the classes keep adherence high.

Living-room friendly home gym for general cardio: WaterRower Natural. Looks like furniture, feels like rowing a boat, lasts forever.

Tight budget under $400: well-reviewed magnetic rower (Sunny Health, MaxKare). Honest about durability limits (3 to 5 years of regular use) but functional.

Rowing as a daily commute substitute or recovery cardio: any reasonable rower. Consistency matters more than which type you pick.
