Quick Answer: A rowing machine measures power per stroke, not how fast you move. Raising your stroke rate from 24 to 32 spm without adding force per pull will make your split worse while exhausting you faster. Most beginners should train at 18–24 strokes per minute with a 1:2 drive-to-recovery ratio, and watch the split — not the rate.

You want a faster split, so you row faster. The rate climbs to 34. Your lungs are on fire. And the split — the number you were actually trying to improve — is worse than when you started.

This is the most common frustration on the erg, and it comes from a reasonable assumption that happens to be wrong: that moving faster produces more speed.

What Does a Rowing Machine Actually Measure?

The flywheel doesn’t know how fast your hands are moving. It knows how hard you accelerated it on the last drive.

Your split (time per 500m) is calculated from power output, and power on the erg comes from one thing: force applied through the drive, stroke after stroke. The rate is just how many times per minute you deliver that force.

The math is unforgiving. Rowing at 20 spm with 200 watts per stroke beats rowing at 32 spm with 120 watts per stroke — and the second one feels roughly three times harder, because you’re spending enormous energy on the recovery phase, which produces exactly zero power.

That’s the whole trap: the rate is the easiest number to change and the least useful one to chase.

Why Do Beginners Row at Too High a Stroke Rate?

Four reasons, all understandable:

1. Faster feels harder, and harder feels productive. Your breathing rate tracks your stroke rate closely, so a high rate genuinely feels like a bigger effort — even when the wattage is lower.
2. The rate number is right there on the screen and responds instantly to what you do. Power per stroke is invisible and takes technique to change.
3. Nobody taught the recovery. New rowers pull hard and then zip back to the catch at the same speed, which forces the rate up whether they want it or not.
4. It exhausts you quickly, and exhaustion is easy to mistake for a good workout.

The result is a rower who is working extremely hard, producing modest power, and getting nowhere. Sound familiar?

Where Does Rowing Power Actually Come From?

Roughly 60% legs, 30% core and back, 10% arms. That ratio is the single most important thing to internalize, because most beginners row it almost backwards — arms first, legs barely involved.

The sequence, in order:

Drive: Legs push. Then the body swings back from the hips. Then the arms pull to the lower ribs. Legs → body → arms. Never simultaneous, never reversed.

Recovery: Exactly the opposite order, and slower. Arms extend. Body hinges forward. Then the knees bend and you slide up to the catch.

The gap between those two speeds is where the whole skill lives.

What Is the Drive-to-Recovery Ratio?

Your drive should be fast and explosive. Your recovery should take about twice as long. That’s a 1:2 ratio.

Count it: “one” on the drive, “two-three” on the recovery. At a 20 spm rate, each full stroke takes 3 seconds — roughly 1 second driving, 2 seconds sliding back.

Do this and two things happen immediately. First, your rate drops naturally, because you’re no longer rushing the slide. Second, your power per stroke goes up, because you arrive at the catch composed and connected instead of crashing into it.

Watch experienced rowers and this is the visible difference: the drive looks aggressive, the recovery looks almost lazy. They’re not resting — they’re setting up.

Is a Higher Damper Setting Better?

No, and this is the other big misconception. The damper is not resistance — it’s a drag factor that changes how much air enters the flywheel housing, which changes the feel of the stroke, not the difficulty.

A damper at 10 feels like rowing a heavy boat: slow, grinding, and hard on the lower back. A damper at 3–5 feels like a racing shell: light and fast. Most competitive rowers train between 3 and 5, which corresponds to a drag factor around 110–130.

Setting the damper to 10 because it “feels harder” is the same error as raising the rate: you’ve made the workout more unpleasant without making it more productive.

How to Practice: A Four-Week Fix

Weeks 1–2 — cap the rate. Row 20 minutes at a strict 18–20 spm. Yes, it will feel slow. Your job is to hold a specific split at that rate. Note your split on day one; you should see it improve by 3–8 seconds within two weeks with no change in effort.

Weeks 3–4 — hold the split, raise the rate. Row 10 minutes at 20 spm holding your target split. Then 5 minutes at 24 spm trying to hold the same split. If the split degrades, drop back. The goal is to earn each rate increase.

Three drills worth adding:

• Legs-only rowing. Arms straight, body still, drive with legs alone for 2 minutes. Teaches you what “legs first” actually feels like.
• Pause drill. Pause for a full second at the finish and again at hands-away. Kills the rushed recovery permanently.
• Film yourself from the side. One 30-second clip on your phone will show you sequence errors that no amount of feeling can detect. Look for: knees rising before your hands pass them (the number one fault), and shoulders opening before the legs finish.

5 Mistakes That Cost You Split

1. Rushing the slide. The recovery should be the slowest part of the stroke. If it isn’t, everything else falls apart.
2. Opening the back too early. Legs finish first. If your shoulders swing while your knees are still bent, you’ve cut your leg drive in half.
3. Bending the arms first. Your arms are the weakest link in the chain. They finish the stroke; they don’t start it.
4. Damper on 10. Costs you your lower back and buys you nothing.
5. Watching the rate instead of the split. The rate is a byproduct. The split is the result. Cover the rate with a piece of tape for a week if you have to — the fifth mistake is the one that quietly undoes the other four.

When to see a professional: persistent lower back pain during or after rowing usually signals early back opening or too high a damper, but if it doesn’t resolve within a week of fixing your technique, get it looked at rather than training through it.

Mini FAQ

What is a good stroke rate for beginners?

18–24 strokes per minute for steady-state work. Race pace for experienced rowers runs 28–36 spm, but that’s built on a stroke that’s already efficient. Starting there just embeds bad habits at speed.

Why is my split not improving even though I’m working harder?

Almost always because the extra effort is going into rate rather than force. Try this test: row 500m at your normal rate, then row 500m at 4 spm slower while pulling noticeably harder on each drive. Most people find the slower version produces a better split at the same or lower heart rate.

What damper setting should I use on a rowing machine?

Between 3 and 5 for most people, which puts the drag factor around 110–130. You can check the actual drag factor in the Concept2 menu — it’s a more reliable number than the damper lever, since dust in the flywheel housing changes the relationship over time.

TL;DR

• The erg measures power per stroke, not stroke rate. Rate is the easiest number to change and the least useful.
• Train at 18–24 spm and hold a target split before raising the rate.
• Sequence: legs → body → arms on the drive, reversed and slower on the recovery.
• Drive-to-recovery ratio of 1:2. Fast pull, slow slide.
• Damper 3–5, not 10. It’s drag, not resistance.
• Watch the split. Ignore the rate.

Row slower, pull harder, go faster. It’s genuinely that counterintuitive.
