Calories Burned Rowing at a moderate effort at 75 kg — 360 kcal per Hour
Rowing at a moderate effort at 75 kg (154–176 lb) burns about 360 kcal per hour. That figure comes from the activity's MET value of 4.8 in the 2011 Compendium of Physical Activities, multiplied by body weight: 4.8 × 75 kg × 1 hour = 360 kcal. This page works the numbers out in full — for 15, 30, 45, 60 and 90 minutes, across all four weight bands, and against four comparable activities at the same weight — so you can plan sessions with real figures instead of guessing.
Rowing at a moderate effort is a smooth, rhythmic full-body exercise: the legs drive, the back swings, and the arms finish each stroke, then the body slides forward to begin again. Whether on the water or on an indoor rowing machine, it works the legs, back, arms and core together while the joints stay low impact — there is no pounding at all. The Compendium rates moderate rowing at 4.8 METs, a moderate intensity, the same as playing cricket.
It suits people who want a full-body workout without running, including those with sore knees, because the movement is seated and smooth. Technique matters more than strength: a good stroke is mostly legs, and beginners who pull only with their arms tire quickly and strain their backs. The headline number to remember is 360 kcal per hour at 75 kg, or about 180 kcal for a 30-minute session. Everything below is an estimate: MET values are population averages, and your own burn will vary with fitness, technique and conditions. That does not make the numbers useless — it makes them a planning tool, and a good one, as long as you treat them as approximate.
Calculate your own numbers
Use the Calorie calculator to work out your own burn for rowing at a moderate effort at your exact weight and session length. Enter your weight, pick the activity and set the duration, and the tool applies the same MET formula shown below. You can also try the Maintenance calorie calculator to see how this session fits into your total daily energy use.

The formula, shown and cited
The standard way to estimate the energy cost of an activity is the MET formula from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8): 1575–1581):
Calories (kcal) = MET × body weight (kg) × duration (hours)
One MET is the energy you use sitting quietly at rest — about 1 kcal per kilogram of body weight per hour. An activity rated at 4.8 METs therefore uses 4.8 times as much energy as resting. The Compendium's MET values come from published studies that measured oxygen use during each activity, so they are measured averages, not guesses. The value used here, 4.8, is the one recorded for rowing at a moderate effort in the FitCalc activity data, taken from the 2011 Compendium.
Worked through for this page:
- MET for rowing at a moderate effort: 4.8
- Body weight: 75 kg (the midpoint of the 70-80 kg band, 154–176 lb)
- Duration: 1 hour
- Calculation: 4.8 × 75 × 1 = 360 kcal
For a 30-minute session the same calculation is 4.8 × 75 × 0.5 = 180 kcal. Nothing else is hidden in the maths — if your weight or duration changes, only those two numbers change.
Your numbers at 75 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 4.8 × 75 × 0.25 | 90 kcal |
| 30 minutes | 4.8 × 75 × 0.5 | 180 kcal |
| 45 minutes | 4.8 × 75 × 0.75 | 270 kcal |
| 60 minutes | 4.8 × 75 × 1 | 360 kcal |
| 90 minutes | 4.8 × 75 × 1.5 | 540 kcal |
That is about 6 kcal per minute of rowing at a moderate effort at this weight. A short session still counts: even 15 minutes burns 90 kcal, and three 15-minute sessions across a day add up to the same 270 kcal as one 45-minute session.
How the burn changes with body weight
The MET value stays the same — it describes the activity, not the person — but the calorie total scales with weight, because a heavier body costs more energy to move:
| Body weight | Calories per hour | Calories per 30 minutes |
|---|---|---|
| 55 kg | 264 kcal | 132 kcal |
| 65 kg | 312 kcal | 156 kcal |
| 75 kg | 360 kcal | 180 kcal |
| 85 kg | 408 kcal | 204 kcal |
Two people doing the same activity for the same time can therefore burn quite different amounts, and that is expected — it is physics, not a mistake in the formula. If your weight sits between two rows, your figure sits between the two values.
How rowing at a moderate effort compares
Here is rowing at a moderate effort against four other activities at the same 75 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 75 kg |
|---|---|---|
| rowing at a moderate effort | 4.8 | 360 kcal |
| playing cricket | 4.8 | 360 kcal |
| playing golf while walking the course | 4.8 | 360 kcal |
| cycling at a leisurely pace (under 10 mph) | 4 | 300 kcal |
| swimming freestyle at a moderate effort | 5.8 | 435 kcal |
Use this table to choose, not to judge. A higher number means a harder session, not a better one: the activity you enjoy and repeat three times a week beats the activity that burns more per hour but that you quit after a fortnight. Mixing intensities across the week — one harder session, two easier ones — is usually more sustainable than doing the hardest activity every time.
Fitting rowing at a moderate effort into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 360 kcal | 720 kcal |
| 3 sessions | 540 kcal | 1080 kcal |
| 5 sessions | 900 kcal | 1800 kcal |
At 4.8 METs, rowing at a moderate effort counts as moderate-intensity activity, so it counts towards the widely used adult activity target of 150 minutes of moderate activity a week. Five 30-minute sessions a week would meet that target entirely and burn about 900 kcal a week at 75 kg. Because the intensity is moderate, it can be done most days, and it pairs well with one harder weekly session for variety.
How to use the result
Learn the stroke order before chasing speed: legs first, then back, then arms on the drive, and reverse it on the recovery. Keep the stroke rate low — around 20 to 24 strokes a minute — and let the legs do most of the work; if your arms tire first, your technique needs adjusting. Two or three sessions of 20 to 30 minutes a week is a good starting habit, and rowing pairs well with a walking or strength routine. Use the numbers on this page to set realistic expectations rather than to chase a daily total. If you are tracking food as well, add the session's calories to your total daily energy expenditure for that day, and remember that the figure is an estimate with roughly 10–20% uncertainty. Do not eat back every calorie the calculator shows: activity trackers and MET estimates both tend to overstate slightly, and a small margin keeps a weight-loss plan on track. If you are aiming to lose weight, keep the deficit modest — 300–500 kcal a day is a common, sustainable range — and keep your total intake above the safety floors of 1,200 kcal a day for women and 1,500 kcal a day for men unless a healthcare professional advises otherwise. On an indoor rower, set the damper to a moderate level (around 4 to 6 on most machines) rather than the maximum — a high damper is not a harder workout, it is just a heavier boat.
What the number does NOT tell you
The MET formula is honest about what it measures and silent about the rest. It does not account for your fitness level: a fit person burns fewer calories doing the same activity than an unfit person, because their body is more efficient. It does not account for body composition — two people at 75 kg with different amounts of muscle and fat will burn slightly different amounts. It does not include the afterburn (excess post-exercise oxygen consumption) that follows hard sessions, it does not measure strength, flexibility or balance gained, and it says nothing about how the activity affects your appetite, sleep or mood. It also cannot tell you whether the activity is safe for you: if you have a heart condition, joint problems, asthma or any other health concern, check with a healthcare professional before starting a new, intense activity. Use the calorie figure as a planning estimate, and judge the activity by how you feel doing it and whether you keep doing it.
The 4.8 MET figure is an average for moderate rowing, but the real cost depends on technique and pace: a strong, efficient rower covers more distance per stroke and may burn less per minute than a beginner fighting the machine, while a faster pace raises the cost quickly. The figure also says nothing about the back: rowing with a rounded lower back or pulling only with the arms is the most common cause of rowing-related back pain.
Frequently asked questions
How many calories do I burn rowing at a moderate effort for 30 minutes at 75 kg?
About 180 kcal. The maths is 4.8 METs × 75 kg × 0.5 hours = 180 kcal. That is an estimate from the Compendium average — your real burn depends on your fitness, your pace and the conditions. If you weigh more or less than 75 kg, use the weight table above to read your own figure.
Is rowing at a moderate effort good for weight loss?
It can help, but only as part of an overall calorie deficit. At 75 kg, an hour of rowing at a moderate effort burns about 360 kcal, which is a solid contribution, but weight loss still comes from the total balance of food and activity across the week, not from one session. Aim for a gradual loss of 0.5–1% of body weight per week, and never drop below 1,200 kcal a day (women) or 1,500 kcal a day (men) without medical supervision.
How does rowing at a moderate effort compare with playing cricket?
At 75 kg, rowing at a moderate effort burns about 360 kcal per hour against 360 kcal for playing cricket. The two are rated identically by this measure — both 4.8 METs — so they burn the same estimated calories at the same weight. The difference between them is the kind of activity, not the energy cost. The best choice is usually the one you will actually do several times a week — consistency matters more than a small difference in the hourly rate.
Does the calorie burn change if I weigh more or less than 75 kg?
Yes, directly. Calories = MET × weight in kg × hours, so the burn scales with body weight. At 75 kg the same hour of rowing at a moderate effort burns about 360 kcal; at 85 kg it burns about 408 kcal. The MET value itself does not change with weight — it describes the intensity of the activity.
How accurate is the 4.8 MET value for rowing at a moderate effort?
It is a population average from the 2011 Compendium of Physical Activities (Ainsworth et al.), which compiled measured energy costs across published studies. The Compendium lists an exact entry for this activity, so the value is not a substitute for a different activity. Individuals still vary by roughly 10–20% around the average because of fitness, body composition, technique and conditions. Treat 360 kcal per hour as a planning estimate, not a precise measurement of your own body.
Is rowing good for people with bad knees?
Usually yes. Rowing is seated and non-weight-bearing, so the knees are loaded gently through a controlled bend rather than pounded as in running. The 4.8 MET rating makes it a moderate-intensity option that still burns a useful 360 kcal per hour at 75 kg. People with knee problems should still start with short sessions, keep the stroke smooth, and stop if a specific movement causes sharp pain — and check with a healthcare professional if they are unsure.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men — consult a healthcare professional before a very-low-calorie diet.
