Rowing machines offer full-body, low-impact cardio, but they are long machines, and they work in very different ways. This guide explains the main resistance types, how much space you really need, and what to check before buying. We include two well-documented examples to show how specifications compare. We have not physically tested these products. Our comparison is based on manufacturer specifications and documented independent research; see our Editorial Policy.
In this guide: Resistance types · Space · Examples · Checklist · FAQ
The four main resistance types
| Type | How it works | Things to know |
|---|---|---|
| Air (flywheel) | A fan creates resistance that rises as you pull harder | Responsive feel; the fan makes a whooshing noise |
| Magnetic | Magnets near a flywheel control resistance | Typically quiet; resistance often set by levels |
| Water | Paddles spin in a water tank | Smooth, natural feel; heavier and needs a full tank |
| Hydraulic | Pistons provide resistance | Often compact and lower cost; feel differs from on-water rowing |
Some newer rowers use electromagnetic systems that let a computer or app control resistance.
How much space a rower needs
Rowers are long. For example, Concept2 lists its RowErg at 8 × 2 ft assembled and recommends a 9 × 4 ft area for use. Always measure the in-use length plus room to get on and off safely, and check whether the machine stores upright, folds or separates.
Short on floor space? Compare options in our guide to home gym equipment for small apartments, or read rowing machine vs. exercise bike.

FAQ
Are rowing machines good for small apartments?
They can be, if the model stores upright or separates. Check the in-use length first; most rowers are long.
Which rowing machine is quietest?
Magnetic and electromagnetic rowers are generally quieter than air rowers. Water rowers make a gentle swishing sound.
Conclusion
Choose the resistance type first, then confirm space and storage. For more cardio options, see walking pads and treadmills.
