Short answer
In the air rower vs magnetic rower choice, pick an air rower if you train hard intervals, want resistance that rises the instant you pull harder, and want split and watts you can compare with gym machines. Pick a magnetic rower if you need a near-silent machine for an apartment, a shorter footprint and set levels you choose with a knob. The muscles and the stroke are the same on both.
Key takeaways
- Air resistance rises with effort; magnetic resistance holds the level you set.
- The setting changes the feel, not the workout: your power sets the effort.
- Magnetic rowers are the quietest and shortest; air rowers are loud and long.
- Air rowers suit intervals and programs written in split or watts.
- Both train the same muscles with the same stroke.
Air and magnetic rowers look alike from the side: a rail, a sliding seat, a foot plate and a handle on a chain or strap. The difference sits inside the front housing. An air rower spins a fan, and the air pushes back. A magnetic rower slows a metal flywheel with magnets set by a knob or lever. That one part changes how the stroke feels, how loud the machine is and how you train on it.
This comparison uses two real examples from our rankings: the Concept2 RowErg, the top pick of our best air rowing machine guide, and the Sunny Health & Fitness SF-RW523021, the top pick of our best magnetic rowing machine guide. Specs come from their Amazon US listings.
Air Rower vs Magnetic Rower at a Glance
The table compares the two systems, with ranges from the pure air and magnetic rowers ranked in our guides. Air + magnetic hybrids sit between the two and are covered further down.
| Criterion | Air rower | Magnetic rower |
|---|---|---|
| How resistance works | Fan: load rises with how fast you pull | Magnets: you set a level and it holds |
| How you adjust it | Pull harder; a damper changes the feel | Knob or lever (16 levels on the models we rank) |
| Stroke feel | Light catch that builds with speed | Even pull at the chosen level |
| Top-end load | No fixed ceiling: the fan keeps pushing back | Capped by the strongest magnet setting |
| Noise (our Noise score) | Loudest: 35/100, a whoosh that grows with effort | Quietest: 100/100 |
| Length in use | 95 to 96 in (hybrids 84 to 91.3 in) | 62 to 79.3 in |
| Max user weight | 500 lb on both pure air models (hybrids 300 to 507 lb) | 300 to 350 lb |

How Each One Feels on the Stroke
On an air rower, the chain spins a fan inside a cage. The faster the fan turns, the more air it has to move and the harder it pushes back. Drive with more power and the load climbs at once; ease off and it drops. There are no levels to pick. A strong rower and a beginner can share one machine at the same setting and both get the session they want.
On a magnetic rower, magnets sit next to a metal flywheel. Turn the knob and they move closer, so the brake gets stronger and each stroke feels heavier. The level holds whether you pull fast or slow, which feels steady and predictable. The catch is the ceiling: with the magnets fully engaged, a strong rower driving hard can outpull the brake and the top levels start to feel light. Owners of some magnetic models report exactly that, as our magnetic guide notes for the Merach Q1S.
A higher setting is not a harder workout on either machine. In a 2008 study on a Concept2, switching the drag factor from 100 to 150 did not change oxygen use, heart rate or blood lactate at submaximal stages. A 2013 study found that the lighter setting brought higher stroke rates and heart rates, while the heavier one was more economical. Your power output sets the effort; the damper or the magnetic level changes how that effort feels.
| Setting | Air rower | Magnetic rower |
|---|---|---|
| Light | Damper low: quick, light catch, higher stroke rate | Low level: easy pull, good for learning |
| Middle | Damper 3 to 5 (the range Concept2 suggests) | Middle levels: most steady rows |
| Heavy | Damper high: heavy catch, tires the legs sooner | Top levels: heaviest pull the magnets allow |
Pro tip: Pick the setting that lets you keep good form for the whole piece. Turning the damper or the knob to the maximum often slows your stroke and wears out your legs before your lungs.
Noise, Space and Power
Noise is the clearest split. A fan moves air, and the whoosh grows with effort, so hard intervals can be heard in other rooms. Our Noise score gives pure air rowers 35 out of 100 and air + magnetic hybrids 50. Magnetic rowers score 100: the brake makes almost no sound, and what you hear is the seat on the rail and the strap. If you share walls or train while others sleep, the magnetic rower is the safe pick.
Size follows the system. The pure air rowers in our guides are 95 inches (GMWD) and 96 inches (Concept2 RowErg) long in use, and the air + magnetic hybrids 84 to 91.3 inches; the magnetic ones run from 62 inches (Dripex) to 79.3 inches (Sunny SF-RW523021). Magnetic models are also lighter, about 41 to 68 lb on their listings, against 57.3 lb for the Concept2 and up to 114 lb for the Aviron. Most magnetic rowers stand upright or fold; the Concept2 separates in two.
Air rowers and manual magnetic rowers need no outlet to create resistance. Electromagnetic rowers, which set the brake with electric current, usually do; our magnetic guide explains the difference.
Training: Intervals, Data and the Muscles You Use
For intervals, the air rower has the edge. The load follows your effort with no button to press between rounds, and the Concept2 PM5 shows 500 m split and watts, the numbers most gym and Hyrox programs use. Among the rowers we rank, only the Concept2 lists both. The Sunny SF-RW523021 shows a 500 m split but no watts; most other magnetic monitors show time, distance, strokes and calories.
For steady rows, both work well. A magnetic rower set to a middle level gives a smooth, even pull for long sessions. Use heart rate to pace either one; our heart rate zone calculator gives you zones.
The muscles do not change with the resistance system. Cleveland Clinic describes the same stroke on any rower: a leg drive, a lean back with the core braced, then an arm pull to the chest, working the legs, glutes, hamstrings, upper back, abs, obliques and lower back. The same form rules apply too: keep the knees tracking straight and pull to the chest, not the chin.
- Air: best for sprints, benchmark pieces and programs written in split or watts.
- Magnetic: best for quiet steady rows, beginners who want a set light level, and shared homes.
- Both: the same stroke, the same muscles, the same technique to learn.
Concept2 RowErg vs Sunny SF-RW523021: Two Real Examples
These two lead their resistance types in our rankings: the Concept2 RowErg scores 87.7 in our best air rowing machine guide and the Sunny Health & Fitness SF-RW523021 scores 79.9 in our best magnetic rowing machine guide. The two scores come from different guides with different weights, so they show how each machine fits its own intent, not a head-to-head result. The Sunny Health & Fitness Air Magnetic Rower shows the hybrid option.

Common Mistakes to Avoid
Mistake 1Treating the damper or the magnetic level as the difficulty of the workout.
Mistake 2Buying an air rower for a shared apartment without thinking about the fan.
Mistake 3Expecting a magnetic rower’s top level to stop a very strong leg drive.
Mistake 4Comparing a split from one brand’s monitor with RowErg numbers.
Mistake 5Ignoring the length an air rower needs in use.
Mistake 6Assuming the two systems work different muscles.
The Bottom Line
- An air rower’s fan pushes back harder the faster you pull; a magnetic rower holds the level you set.

Frequently Asked Questions
An air rower is better for hard intervals and programs written in split or watts, and the Concept2 RowErg leads our air guide. A magnetic rower is better for quiet homes and short rooms, and the Sunny Health & Fitness SF-RW523021 leads our magnetic guide. The muscles worked are the same.
The magnetic rower, by a wide margin. Its brake makes almost no sound, so our Noise score gives it 100 out of 100. A pure air rower scores 35: the fan whoosh grows as you pull harder. Air + magnetic hybrids score 50.
Not by themselves. Your power output sets the workout on any rower. A 2008 study on a Concept2 found no change in oxygen use, heart rate or lactate at submaximal stages between two drag settings. Air rowers do make intervals easier to run because the load follows your effort instantly.
The magnets have a maximum strength. A strong rower who drives hard with the legs can outpull it, so the stroke feels light. Focus on a powerful leg drive at a moderate level, or consider an air rower, which has no fixed ceiling.
A hybrid with a fan and a magnetic brake on the same flywheel. You pick a magnetic level for a base load, and the fan adds load as you speed up. The Sunny Health & Fitness Air Magnetic Rower offers 16 magnetic levels. It is quieter than a pure fan but not silent.
Yes. You can set a light level and keep it while you learn the legs, body, arms sequence, and it is quiet. An air rower works for beginners too: row gently and the fan stays light. Our beginner guide ranks magnetic models highest for this intent.
