Pulling with the arms, a rounded back, damper on 10: the most common beginner mistakes in rowing — and how to fix each with a clear correction.
Which mistake slows beginners down the most in rowing? The honest answer: pulling with the arms. Whoever flips the order and starts with the arms wastes power — because about 43 % comes from the legs, 36 % from the trunk and only 21 % from the arms — and slams the load into the lower back. Almost all typical beginner mistakes come down to the same thing: a disrupted order or a rounded back.
The good part: each of these mistakes has a clear, simple correction. In this guide we go through the five most common — from the arm pull to the rounded back to the cranked-up damper — and you get the concrete fix for each. And because you often can't feel your own mistake, I'll show you at the end how to expose them with a simple video.
The classic. The arms bend before the legs are done — power is lost. Correction: keep the arms fully straight until the knees are nearly extended; only then does the trunk open, and last of all the arms pull. Think: legs–trunk–arms.
Under fatigue the pelvis tips and the spine flexes — the main route to back pain on the erg. Correction: sit on your sit bones, keep the lower back flat, tip from the hips instead of the back.
Opening the trunk already at the catch creates a hump in the force curve: the handle is pulled up, the blade dives, the drive stalls. Correction: keep the trunk quiet until the legs have started the drive.
Many set the damper to 8–10 because "harder = better". That only tires the muscles before you get the endurance benefit and tempts you to yank. Correction: damper 3–5, create the resistance through your own force.
Frantic rowing at 26+ strokes blurs the order and cements mistakes. Correction: back to 18–22 strokes per minute, a long recovery, ratio about 1:2.
The most dangerous mistake is the rounded back under load: it's the direct route to low back pain. Keep the spine neutral, initiate every drive from the legs, and don't crank the damper to compensate for strength. Distinguish muscle burn from real back or joint pain — the latter means stop and check technique. Warm up before every session.
Never correct two mistakes at once. Take exactly one per session — for example "arms stay long" — and film the last ten strokes to check whether it's gone. This one-mistake rule sounds slow but is the fastest route to clean technique, because your brain reliably automates one thing instead of five half-way.
From the legs. In trained rowers about 43 % of stroke power comes from the legs, 36 % from the trunk and only 21 % from the arms. The arms merely transfer the force to the handle; they don't generate it. That's why "pulling with the arms" is the most expensive beginner mistake.
On the drive: extend the legs first, then open the trunk, and pull the arms last. On the recovery exactly in reverse: extend the arms, tip the trunk forward, then bend the knees. Flip this order and you waste power and load the lower back.
Set the damper to 3 to 5. Higher settings feel "harder" but only tire the muscles before you get the endurance benefit and tempt you into a back-loading yank. You create the real resistance yourself through the force of your drive.
Keep the lower back neutral and never row with a rounded back — under fatigue the spine flexes the most and that's exactly what overloads the lower back. Sit on your sit bones, tip from the hips, and stop at real pain instead of pushing on.
