How to Use a Rowing Machine: Form, Muscles Worked & Calories

Quick Answer: If you have just bought an erg — or keep walking past one in the corner of your gym — and want to learn how to use a rowing machine properly, here is the whole lesson in one sentence: sit tall, strap your feet in, and think “legs, swing, arms” on the way back and “arms, swing, slide” on the way in. Rowing is roughly 60% legs, with your back and arms finishing the stroke — which is why it burns like running but lands softly like cycling. Get the order right and you will feel the work in your thighs and lungs. Get it wrong and your arms will give up long before the rest of you.

The Stroke in 4 Parts

Every stroke on every machine — a Concept2, a water rower, the dusty one at the hotel gym — has the same four phases. Learn them in order and everything else (damper setting, pace, workouts) suddenly makes sense.

1. 1) The Catch. The starting position: shins vertical, knees bent, arms straight and reaching toward the flywheel, torso hinged slightly forward from the hips — proud chest, not slumped shoulders — with the shoulders in front of your hips. Think of it as a coiled spring. Do not rush this position: a sloppy catch sets up a sloppy drive.
2. 2) The Drive. Now go — in the right order. Push the legs down first: the legs are the engine of the stroke, supplying about 60% of the power. As the legs extend, swing the torso open to a slight lean-back. Only after the legs are nearly flat do the arms bend, drawing the handle to your lower ribs. Legs, then body, then arms — a chain. Most beginners do the exact opposite, pulling with the arms while the knees are still bent, which is like towing a trailer with the handbrake on.
3. 3) The Finish. The end of the pull: legs flat with knees down (not jammed straight), a slight lean-back of about 1 o’clock — roughly 10-15 degrees past vertical; lean farther and you strain your lower back for zero extra speed — handle touching your lower ribs, elbows drawn behind you, shoulders down and away from your ears.
4. 4) The Recovery. The way back is the mirror image, in reverse order: arms straighten away FIRST, then hinge the torso forward from the hips, then — and only then — let the knees bend and slide the seat up to the catch. The recovery takes about twice as long as the drive: count “one” on the drive and “two-three” coming back.

What Muscles Do Rowing Machines Work?

The short answer: nearly all the big ones, in a single stroke. Here is how the work splits up.

• Legs first. Your quads and glutes drive about 60% of the power of each stroke, with the hamstrings and calves helping through the middle of the drive. If your thighs are not working by minute ten, you are rowing with your arms.
• Back. Your lats pull the handle home in the second half of the drive, while your traps and spinal erectors work the whole time just to hold you in good posture against the pull.
• Core. Your abs and obliques brace every single stroke to connect the leg drive to the handle pull — hundreds of small bracing reps, no crunches required.
• Arms and grip. Your biceps and forearms finish the pull. They contribute the last 10-15% of the stroke — the garnish, not the main course.

You will see viral claims that rowing uses “86% of your muscles.” The honest version: rowing does use an unusually large share of total muscle mass for a cardio machine — more than a treadmill, more than a bike, probably more than anything else in the cardio corner — but the exact percentage is marketing, not science. Nobody has measured all 600-plus muscles mid-stroke. The true point is simpler: legs plus back plus arms, in one low-impact motion, every rep.

Settings That Matter

Three settings decide whether your first row feels smooth or feels like a backache. None of them is “just crank it to 10.”

The damper (the lever on the flywheel)

The damper is the lever numbered 1-10 on the side of the flywheel, and here is what almost everyone gets wrong: it is NOT resistance like on a spin bike. It controls air flow into the flywheel — drag, not weight. Setting 10 does not make you stronger; it just makes the handle feel heavy and sluggish, which punishes bad form. Beginners and most training: damper 3-5. That range feels quick and smooth, and it is where most efficient rowing happens. Elite rowers rarely live at 10 either. Parking the damper at 10 with beginner form is a lower-back strain recipe, not a badge of toughness.

Foot straps and footplate

Strap in snug over the widest part of your foot — tight enough that your feet stay planted through the drive, loose enough that your heels can lift slightly at the catch. Set the footplate so the strap crosses near the ball of the foot; if it cuts across your toes or ankle, move the plate.

Strokes per minute

While you are learning, aim for 20-24 strokes per minute — slow enough to think through the sequence on every rep. For steady training, 24-30 spm is the sweet spot. Faster is not better if the form dissolves: a sloppy 36 spm produces less useful power than a crisp 24.

Calories Burned on a Rowing Machine

Here is the honest math, using the standard formula (kcal per minute = METs x 3.5 x body weight in kg / 200), with moderate rowing at about 7 METs and vigorous rowing at about 12 METs. These are 30-minute totals:

Body weight	Moderate (~7 METs), 30 min	Vigorous (~12 METs), 30 min
120 lb (55 kg)	202	347
154 lb (70 kg)	257	441
185 lb (85 kg)	312	536
220 lb (100 kg)	368	630

A word about the machine’s monitor: its calorie readout guesses your weight and your effort, and it usually guesses generously. Treat it as a rough trend, not a bank balance. Rowing’s real advantage is that it pairs this burn with near-zero joint impact — it is one of the best tools there is for long, easy Zone 2 cardio. (Here is how to find your Zone 2 heart rate.)

5 Form Mistakes That Steal Your Power

Watch any gym’s rowing corner for ten minutes and you will see all five of these. Fix them in order and your split will drop without any extra fitness.

1. Pulling with the arms before the legs finish

You yank the handle while your knees are still bent, so your arms do the legs’ job and tire in minutes. Fix it: keep your arms straight as rods until your legs are nearly flat. Say “legs” in your head, and do not bend the elbows until you mean it.

2. Rushing the slide back

You slam the seat forward, the handle crashes into your knees, and you arrive at the catch breathless and off balance. Fix it: count the stroke — “one” for the drive, “two-three” for the slow, deliberate return.

3. Yanking the handle to your chin or neck

The handle belongs at your lower ribs, elbows sweeping behind you. Pulling it high shrugs your shoulders toward your ears and bleeds power. Fix it: aim for the bottom of the ribcage — the same spot, every stroke.

4. Rounding the lower back at the catch

Slumping into a C-shape at the front of the stroke loads your spinal discs instead of your hips. Fix it: hinge forward from the hips with a flat, proud back. If tight hamstrings will not allow it, bend the knees more rather than rounding.

5. Death-gripping the handle

White knuckles, forearm pump, blisters — and zero extra watts. Your hands are hooks, not clamps. Fix it: hold the handle with relaxed fingers and flat wrists. If your forearms are the sorest part of you afterward, that is a technique flag, not a badge of honor.

Your First Two Workouts

You do not need a 45-minute sufferfest to start. These two sessions build the stroke and the engine in the right order.

Workout A — 10 minutes, day 1 (intervals)

Two minutes easy warm-up at about 20 spm, barely pushing — just rehearsing the sequence. Then 6 rounds of 30 seconds firm / 30 seconds easy: during the firm pieces, drive the legs a little harder while keeping the same slow 20-24 spm rhythm and clean form; the easy pieces are full recovery. Finish with a 2-minute cool-down. The goal is not exhaustion — it is six clean repetitions of the sequence under a little pressure.

Workout B — 20 minutes steady

Row 20 minutes at a pace where you can speak in short sentences — that is your aerobic zone. Note your average split (the time per 500 m on the monitor) when you finish, and repeat this exact session weekly: the split will fall as your form and fitness improve, which is the most motivating number in rowing. When you want a structured plan that layers strength on top of cardio, this beginner workout plan is the natural next step.

Frequently Asked Questions

The bottom line: a rowing machine rewards technique far more than effort. Ten crisp minutes at 22 strokes per minute will do more for your fitness — and your joints — than thirty frantic minutes at the wrong damper setting. Learn the legs-swing-arms order, keep the damper between 3 and 5, fix the five mistakes above one at a time, and let your split fall. The machine is patient. Be patient too.

How do you know it is working? Track two numbers once a week: your average split over a steady 20-minute row at a conversational effort, and your stroke rate. When the split falls at the same effort and the same stroke rate, your technique — not your fitness — did the work. That is the beauty of the erg: it is a ruthlessly honest feedback machine. And if you ever plateau, the answer is almost never “row harder.” Go back to the four phases, slow the slide down, check the damper is still at 3-5, and give it another week. Form first, fitness follows.

Note: calorie burn varies with your weight, effort and technique — use the table as a starting estimate, and re-test your split monthly to see your progress.
