The damper is not a difficulty knob

Walk past the rowers in most gyms and they’ll all have one thing in common: the damper’s on 10. There’s a stubborn myth that the lever on the side of the flywheel is a “difficulty knob” — a level, like the incline on a treadmill. It’s one of the most misunderstood parts of the machine.

Setting the damper to 10 doesn’t mean you’re working harder. It just changes how the machine feels — often for the worse.

What drag factor actually is

The damper controls how much air gets into the flywheel housing. Higher (10) lets in more air, so the flywheel slows down faster between strokes. Lower (1–3) lets in less, so it keeps spinning more freely. That’s “drag factor”.

Think of it like gears on a bike. A high damper is a heavy gear — hard to get moving, big grunt per stroke. A low damper is a light gear. Plenty of experienced rowers train at a lower setting than you’d expect, closer to the middle of the range than the top — many sit around a damper of 3 to 5, which on most machines puts the drag factor near 120.

Why “heavier” isn’t “better”

Row on a damper that’s too high and it’s much harder to hold good technique. The heavy load tempts you to yank with your arms and back because your legs can’t overcome it fast enough — which fatigues you early and loads your lower back.

Ease the damper down and the flywheel spins more freely, encouraging a faster, more explosive leg drive — where the real power in rowing comes from. You’ll hold better rhythm and row longer with more quality.

Find your setting

Here’s the best-kept secret: you can often work harder at a lower damper. Because the machine’s easier to move, you can put more power through your legs and get a better split without the heavy, grinding feel that wrecks your form.

Next time, ignore the “10”. Start lower and see how much more powerful you feel.
