The rowing ergometer: technique, common mistakes, and who it suits

The rowing ergometer is one of the few machines that loads legs, back and arms in a single movement without pounding your joints the way running does. The trouble is that most people use it wrong: they pull with the arms, sit hunched over, and after ten minutes their lower back hurts instead of their legs. Here is what a correct stroke looks like, which mistakes keep showing up, and who the machine actually suits.

What the erg actually trains

By force distribution, one stroke is roughly 60% legs, 30% trunk and back, 10% arms. If your arms fatigue before your legs, your technique is wrong — there is no exception to that rule. The resistance is self-adjusting: the harder you pull, the harder it gets, so the intensity comes from you, not from a setting.

Set-up before the first stroke

• Damper lever: 3 to 5, not 10. Ten does not mean harder, it means a slower flywheel and more load on your back. If the monitor shows a drag factor, aim for 110–130 for men and 100–120 for women.
• Footplates: the strap crosses the ball of the foot, just below the toes. If your heels lift completely through the whole drive, drop the footplate one setting.
• Grip: fingers over the handle, thumb underneath, flat wrists, relaxed — about as tight as carrying a bag of groceries.
• Monitor: watch the 500 m split and the stroke rate (spm). Those two numbers tell you everything about the session.

The stroke in four phases

1. Catch

Shins vertical, heels slightly raised, shoulders in front of the hips, back flat, trunk leaning forward about 10–15 degrees. Arms straight, chain horizontal. If your shins pass your toes, you have gone too far up the slide.

2. Drive

The order never changes: legs — body — arms. Push the footplate away while your arms stay straight, then open the trunk, then pull the handle in. It takes about one second and carries almost all the force.

3. Finish

Handle to the bottom of your ribs, elbows past the body, trunk leaning back about 10–20 degrees. Do not pull to your neck and do not throw yourself backwards.

4. Recovery

Reverse order: arms — body — legs. Hands clear the knees first, then the trunk hinges forward, and only then do the knees bend. The recovery should take about twice as long as the drive — a 1:2 ratio. If your recovery is as fast as your drive, you are rating 40 spm and going nowhere.

The most common mistakes

1. Arms bending before the legs finish. Force leaks out and the biceps does the quadriceps job.
2. Opening the back too early. The trunk swings back while the knees are still bent — the classic reason your lower back hurts after 10–15 minutes.
3. Rounded back at the catch. If you cannot hold a neutral spine at full compression, shorten the slide and stop before the lumbar rounds.
4. Shooting the slide. The seat travels back but the handle does not — your legs are stronger than your trunk, and the trunk collapses.
5. Damper on 10. For most people it is like rowing through wet sand: fewer strokes, more back load, worse technique.
6. High rate, low force. 32 spm at a 2:40 split means you are flailing; 22 spm at 2:20 is the better session.

What a concrete session looks like

Warm-up is always 5–10 minutes of easy rowing at 18–20 spm, plus 10 bodyweight squats and 10 shoulder circles.

• Beginner (first 4 weeks): 3 times a week, 15–20 minutes at 20 spm, with a 1-minute break every 5 minutes to check your technique.
• Base endurance: 30–40 minutes continuous at 20–22 spm, at a pace where you can still speak in short sentences.
• Intervals: 5 x 500 m with 2 minutes rest at 26–28 spm. The goal is for the last 500 m to be no more than 3 seconds slower than the first.
• Short and sharp: 10 x 30 seconds on / 30 seconds off, 10 minutes total — useful when you only have 20 minutes.
• Test: a maximal 2000 m once every 8–12 weeks. No more often than that; it is brutal, and technique falls apart when you are wrecked.

Who it suits, and who it suits less

It works well for people carrying extra body weight whose knees dislike running, for anyone returning after a long break, and for people short on time, since 20 minutes gives you both cardio and leg work. It is also a solid supplement to strength training, twice a week.

It suits you less if you cannot hold a neutral spine because of stiff hips or limited ankle mobility — fix the mobility first. The same goes for acute low back pain and fresh shoulder injuries: the erg repeats the identical movement 200-plus times per session, so a small fault turns into an irritation fast.

When to see a doctor

• Chest pain, tightness, or shortness of breath out of proportion to the effort — stop immediately and get checked.
• Pain radiating from the back down the leg, pins and needles, or foot weakness.
• Low back pain lasting more than 2 weeks or waking you at night.
• Dizziness, an irregular heartbeat, or fainting during effort.
• If you have diagnosed heart disease, uncontrolled high blood pressure, or you are pregnant, agree the training load with your doctor before you start.

The short version

• A stroke is 60% legs, 30% trunk, 10% arms — drive legs–body–arms, recover arms–body–legs.
• Damper 3–5, recovery twice as slow as the drive, handle to the bottom ribs.
• Most common faults: early arm bend, early back opening, rounded back at the catch.
• Start with 3 sessions a week of 15–20 minutes at 20 spm; test 2000 m at most every 8–12 weeks.
• Chest pain, tingling down the leg, or back pain past 2 weeks means a doctor, not another session.
