Rowing with Weak Arms: Building Upper Body Strength

Weak arms are less of a problem in rowing than most newcomers expect. The arms are the smallest engine in the stroke, and the best fix is usually technique first and gentle strength work second.

What the arms do

The stroke is driven mainly by the legs, then the swing of the body, and only then the arms. As a rough rule, most of the work comes from the legs and trunk, and the arms add the final part of the pull and then control the handle on the recovery. The arms also work as links, transmitting the force from your back and legs to the handle, which means they must be strong enough to hold a straight position under load rather than bending too early.

If you feel your arms burning first, it is almost always a sign that they are doing too much, not that they are too weak. Common causes are pulling with the arms at the start of the drive, a very high drag factor, or a tight grip.

Use them last

Think of the stroke in sequence.

1. Catch. Arms straight, shoulders relaxed, shins near vertical.
2. Drive: legs. Push with the legs and keep the arms straight. The handle should barely move relative to your body.
3. Drive: body. Swing the trunk back from the hips once the legs are most of the way down.
4. Drive: arms. Draw the handle to your lower ribs at the end, keeping the elbows close to your body.
5. Recovery. Arms first, then body, then legs, in reverse order.

If your arms bend early, you waste the large muscles and overload the small ones. See common rowing technique faults for the frequent errors, and how to row faster for the bigger picture.

Drills that teach the sequence

• Arms only. Sit at the finish position with legs flat. Row 10 strokes with just the arms, then 10 with arms and body, then 10 with the full stroke. Use these as a warm-up, not a workout.
• Pause drill. Pause for a second at the knees on the drive, with arms still straight, then continue. This teaches you to hold the arms straight until the handle passes the knees.
• Pick drill. Alternate 10 strokes of arms and body, 10 of three-quarter slide, then 10 full strokes.
• Slow recovery. Count two on the drive and three or four on the recovery. A calm recovery keeps the forearms from tightening.

Build strength gradually

Upper-body strength helps you hold position and finish strongly. Keep it simple, with two sessions a week on non-hard-rowing days if possible.

Exercise	Sets and reps	Notes
Push-ups (incline if needed)	3 x 8 to 12	Keep the body in a line
Dumbbell or band rows	3 x 10 to 12	Pull the elbow back, shoulder blade down
Lat pulldown or assisted pull-ups	3 x 6 to 10	Controlled, full range
Biceps curls	2 x 10 to 12	Light and steady
Triceps extensions or dips	2 x 10 to 12	Elbows tucked
Plank	3 x 30 to 45 seconds	Supports the trunk

Start with light weights and add a little at a time. Stop a set when your form goes, not when you are completely exhausted. Our strength training for rowing guide shows how to build a wider weekly plan, and rowing to build strong arms covers what rowing alone does for the arms.

Keep the rowing steady

You do not need to row hard to improve arm endurance. Easy sessions of 20 to 40 minutes at a conversational pace, with relaxed grip and flat wrists, teach your arms to work economically. Keep the drag factor moderate rather than maximal. See drag factor explained.

Quick checks

• Are my arms staying straight until the handle passes my knees?
• Is my grip loose on the recovery?
• Does the handle finish at my lower ribs, not my chest?
• Do my shoulders stay down?

If you answer no to any of these, fix it before adding more weights.

When to see someone

Pain in the elbow, wrist or shoulder, numbness or tingling is not a weakness issue. Stop and speak to a GP or physiotherapist. If pain increases while you row, stop.
