Quick Answer: A rowing stroke is roughly 60 percent legs, 30 percent hips and back, 10 percent arms. If your arms and grip fatigue first, you are pulling with them instead of pushing with your legs. The fix is sequencing: legs, then hips, then arms on the drive, and the exact reverse on the recovery — arms away, body over, then knees bend. This is general information, not medical advice.

You finish a 2,000 metre piece and your forearms are pumped, your grip is going, and your lower back is complaining.

Your legs — by far the largest muscles you own — feel like they have barely worked.

That is a sequencing problem, and it is the single most common fault in indoor rowing. It limits your power output, it puts load on structures that are not built for it, and it is why the pace feels so much harder than the numbers suggest it should.

What is the actual power distribution?

Roughly 60 / 30 / 10, and most people’s stroke is closer to 30 / 30 / 40.

Legs: about 60 percent. The drive begins as a leg press. Quads, glutes and hamstrings are the largest muscles in the body, and the stroke is designed around them.

Hips and back: about 30 percent. The body swing from roughly 11 o’clock to 1 o’clock, driven by the hips rather than by rounding and unrounding the spine.

Arms: about 10 percent. The final draw to the ribcage. Arms are the smallest contributor and they fatigue fastest, which is why an arm-dominant stroke cannot hold a pace.

The diagnostic is simple: what hurts. Legs and glutes fatiguing first means the sequence is broadly correct. Forearms, grip, biceps or lower back fatiguing first means power is coming from the wrong place. This is more reliable than watching yourself in a mirror, because sequencing faults are hard to see and impossible to miss in the fatigue pattern.

What is the correct sequence?

Legs, body, arms on the drive. Arms, body, legs on the recovery. In that order, every time.

The drive. From the catch, push the legs down while the arms stay straight and the body angle holds. Only once the legs are most of the way down does the body swing back. Only once the body has swung do the arms draw in. Each segment finishes before the next begins — the power passes along a chain rather than everything firing at once.

The recovery is the reverse, and it is where most people rush. Hands away from the body first, then hinge the torso forward from the hips, and only then let the knees break. Bending the knees before the hands have cleared means lifting the handle over them, which is where the awkward hitch in most people’s stroke comes from.

The ratio should be about 1:2. The drive is fast, the recovery is roughly twice as long. Most beginners rush the recovery and end up at the catch unprepared, which forces an arm-led drive. Slowing the recovery is the single fastest fix for most stroke problems.

A useful cue: push the footplate away, do not pull the handle. Thinking of the stroke as a leg press with a handle attached reorders the sequence almost automatically.

How do you know if you are actually fixing it?

Four checks, all available on any erg.

Watch the split at a lower rate. If you can hold the same pace at a lower stroke rate, you are producing more power per stroke — which is what better sequencing produces. Rate down, split the same, is the clearest evidence of improvement.

Check where you fatigue. After several weeks of correct sequencing, legs should be the limiting factor. This is a slower-moving indicator but the most meaningful one.

Look at the force curve if your monitor shows one. A good stroke produces a smooth curve rising early and peaking in the first half. A double-humped or late-peaking curve indicates the segments are not connected — usually arms breaking early or the body swinging before the legs finish.

Film yourself from the side for ten strokes. At the catch, shins should be roughly vertical, arms straight, torso hinged forward from the hips with a flat back. At the finish, legs flat, body at about 1 o’clock, handle at the bottom of the ribcage. Two positions, easy to check.

One number worth knowing: a stroke rate over 30 for steady work is usually a sign of rushing the recovery. Most useful aerobic rowing happens at 18 to 24 strokes per minute.

5 Mistakes Everyone Makes on the Erg

1. Pulling with the arms first. The root fault behind almost everything else. Arms stay straight until the legs are down.

2. Rushing the recovery. Producing a 1:1 ratio instead of 1:2, arriving at the catch compressed and rushed, and having no option but to yank. Slow the hands away.

3. Setting the damper to 10. The damper is not resistance in the way people assume — it changes the feel of the stroke, roughly analogous to boat type. Most effective training happens at 3 to 5, and a damper at 10 encourages a slow, grinding, back-dominant stroke.

4. Rounding the lower back at the catch. The hinge should come from the hips with a neutral spine. Rounding under load at the catch is the most common source of rowing-related back complaints, and the third mistake makes it considerably more likely by increasing the force at that position.

5. Gripping the handle too hard. A light hook grip with the fingers is enough. A tight fist fatigues the forearms early, and grip is a common limiter for people who otherwise have plenty of aerobic capacity left.

FAQ: Indoor Rowing Questions, Answered

What damper setting should I use?

Between 3 and 5 for most training. Higher settings feel harder but encourage a slower, more strength-dominant stroke that is less useful aerobically and harder on the back. Elite rowers largely train in this range too.

Why does my lower back hurt after rowing?

Most often from rounding the spine at the catch, or from initiating the drive with the back before the legs. Both are sequencing faults rather than strength problems. Film yourself from the side and check that the hinge is coming from the hips with a flat back. If pain persists, stop and get it assessed — this is general information and not medical advice.

How long should a beginner session be?

Twenty to thirty minutes of steady rowing at a conversational effort, two or three times a week, is a good starting point. Prioritise holding good sequencing over holding a pace; technique degrades under fatigue, and grooving a bad pattern for thirty minutes is worse than rowing well for fifteen.

TL;DR:

• A rowing stroke is roughly 60 percent legs, 30 percent hips and back, 10 percent arms. Fatiguing in the forearms means the sequence is inverted.
• Drive: legs, body, arms. Recovery: arms, body, legs. Each segment finishes before the next starts.
• Slow the recovery to a 1:2 ratio — it is the single fastest fix for most stroke faults.
• Set the damper to 3 to 5, grip lightly, and hinge from the hips rather than rounding the back at the catch.

The satisfying thing about fixing erg sequencing is that it makes you faster without making you fitter first — the power was always available, it was just being routed through the smallest muscles in the chain. Spend two sessions rowing deliberately slowly at rate 18, thinking only about pushing the footplate away, and then check your split at your normal rate. Most people find a few seconds sitting there waiting for them. This is general information rather than medical advice.
