Rowing Machine vs Running: Which Burns More Calories?
The definitive, science-backed comparison of indoor rowing and running — covering calorie burn, muscle activation, joint impact, cardiovascular benefits, weight loss, and long-term sustainability. Based on MET values from the Compendium of Physical Activities and the 2019 ACE-sponsored energy expenditure study.
TL;DR — The Quick Verdict
Running burns slightly more calories per minute at equivalent perceived effort — roughly 10–20% more according to the ACE-sponsored study comparing 10 indoor exercise machines. At a “somewhat hard” intensity (RPE 13), a treadmill burns approximately 12.2 kcal/min versus 9.8 kcal/min on a rowing machine for a 155 lb person.
However, rowing activates 86% of your muscles compared to running’s approximately 50%. Rowing is zero-impact, builds upper body strength, and has a significantly lower injury rate. For most people — especially those over 35, carrying extra weight, or with joint concerns — rowing is the better long-term choice for sustainable fitness and body composition.
Calorie Burn: The Numbers
Let’s start with what most people want to know: raw calorie burn. The following table shows estimated calories burned in 30 minutes for a 155 lb (70 kg) person, based on MET values from the Compendium of Physical Activities — the gold standard reference used by exercise physiologists worldwide. The formula is straightforward: Calories = MET × body weight (kg) × duration (hours).
| Activity | MET | Cal / 30 min | Cal / 60 min |
|---|---|---|---|
| Rowing — light effort | 3.5 | 129 | 257 |
| Rowing — moderate effort | 7.0 | 257 | 514 |
| Rowing — vigorous effort | 8.5 | 312 | 624 |
| Rowing — very vigorous | 12.0 | 441 | 882 |
| Running — 5 mph (12 min/mi) | 8.3 | 305 | 609 |
| Running — 6 mph (10 min/mi) | 9.8 | 360 | 720 |
| Running — 7 mph (8.5 min/mi) | 11.0 | 404 | 808 |
| Running — 8 mph (7.5 min/mi) | 11.8 | 433 | 867 |
| Running — 10 mph (6 min/mi) | 14.5 | 532 | 1,065 |
Key takeaway: At comparable intensities, running burns roughly 10–20% more calories per minute than rowing. However, the gap narrows significantly at higher intensities. A very vigorous rowing session (12.0 METs) burns more calories than a moderate 6 mph run (9.8 METs). The intensity you can sustain matters far more than the modality you choose.
There is an important caveat: these MET values represent averages across populations. Your actual calorie burn depends on your body weight, fitness level, technique efficiency, and the specific intensity you maintain. A trained rower on a Concept2® RowErg can sustain 200+ watts for extended periods, pushing their calorie burn well above 800 calories per hour — comparable to running at 8 mph. The PM5 monitor on a Concept2 ergometer provides real-time calorie data based on actual mechanical work output, making it one of the most accurate calorie tracking tools available in any exercise modality.
What Are MET Values and Why Do They Matter?
A MET (Metabolic Equivalent of Task) represents the energy cost of an activity relative to sitting at rest. One MET equals approximately 3.5 mL of oxygen consumed per kilogram of body weight per minute, or roughly 1 kcal per kilogram per hour. When an activity is rated at 7.0 METs (moderate rowing), it means you are burning 7 times more energy than you would sitting still.
MET values come from the Compendium of Physical Activities, a research database maintained by Arizona State University that has been cited in over 2,000 peer-reviewed studies. The compendium assigns MET values based on laboratory measurements of oxygen consumption during standardized exercise protocols. This makes MET-based comparisons the most scientifically rigorous way to compare calorie burn across different activities.
MET Intensity Categories
Muscle Activation: Full Body vs Lower Body
This is where rowing and running diverge most dramatically. Running is primarily a lower-body exercise that engages the quadriceps, hamstrings, glutes, and calves. While your core provides stabilization and your arms swing for balance, the upper body does minimal work. Rowing, by contrast, is a true full-body exercise that recruits 86% of your skeletal muscles in every single stroke.
| Muscle Group | Rowing | Running |
|---|---|---|
| Quadriceps | PRIMARY | PRIMARY |
| Hamstrings | PRIMARY | PRIMARY |
| Glutes | PRIMARY | PRIMARY |
| Calves | SECONDARY | PRIMARY |
| Latissimus Dorsi (Lats) | PRIMARY | — |
| Rhomboids & Traps | PRIMARY | — |
| Biceps | PRIMARY | — |
| Deltoids (Shoulders) | SECONDARY | MINIMAL |
| Core (Abs & Obliques) | PRIMARY | SECONDARY |
| Erector Spinae (Lower Back) | PRIMARY | SECONDARY |
| Forearms & Grip | PRIMARY | — |
| Hip Flexors | SECONDARY | PRIMARY |
Legs provide 60% of power, core transfers 20%, arms and back finish with 20%. The rowing stroke is a coordinated chain from feet to fingertips.
Primarily lower body: quads, hamstrings, glutes, calves, and hip flexors. Core stabilizes, but upper body contribution is minimal.
The practical implication is significant: rowing provides a strength-endurance stimulus to your upper body that running simply cannot match. Over months of consistent training, rowers develop noticeable back, shoulder, and arm definition alongside their leg strength. Runners develop exceptional lower-body endurance but may need separate strength training to maintain upper-body muscle mass — especially important as we age and naturally lose muscle.
Joint Impact & Injury Risk
This is perhaps the most important comparison category for long-term health and training sustainability. Running is a high-impact activity: every stride sends a ground reaction force of 2.5–3.0 times your body weight through your ankles, knees, and hips. For a 155 lb runner, that is 390–465 lbs of force per step. At a cadence of 170 steps per minute, a 30-minute run produces approximately 5,100 impact events.
| Factor | Rowing | Running |
|---|---|---|
| Impact per repetition | Zero (seated, no ground contact) | 2.5–3.0× body weight |
| Impact events per 30 min | 0 | ~5,100 steps |
| Annual injury rate | ~2–5% (mostly lower back) | ~37–56% of recreational runners |
| Common injuries | Lower back strain, rib stress (rare) | Shin splints, runner's knee, plantar fasciitis, IT band, stress fractures |
| Suitable for overweight individuals | Excellent (no weight-bearing stress) | Higher injury risk at higher body weights |
| Post-injury rehabilitation | Often recommended by physios | Usually restricted during recovery |
| Bone density stimulus | Minimal (non-weight-bearing) | Significant (weight-bearing impact) |
The injury statistics are striking. Research published in the British Journal of Sports Medicine found that 37–56% of recreational runners sustain at least one running-related injury per year. The most common are runner’s knee (patellofemoral pain syndrome), shin splints, plantar fasciitis, Achilles tendinopathy, and IT band syndrome. By contrast, rowing injuries are relatively rare and almost exclusively related to poor technique (lower back rounding) rather than the inherent mechanics of the exercise.
The one area where running has a clear advantage is bone density. Weight-bearing impact stimulates osteoblast activity and increases bone mineral density — an important consideration for osteoporosis prevention, particularly in women. Rowers should supplement with weight-bearing exercises (walking, squats, lunges) to maintain bone health.
Cardiovascular Benefits
Both rowing and running are exceptional cardiovascular exercises. The 2019 ACE-sponsored study found that both modalities can elevate heart rate into the target training zone at moderate perceived effort. However, there are meaningful differences in how each exercise stresses the cardiovascular system.
VO2max Development
Both rowing and running are effective for improving VO2max. Running typically produces slightly higher peak VO2 values because it involves weight-bearing locomotion with greater postural muscle recruitment. However, elite rowers achieve some of the highest VO2max values in all of sport — often exceeding 70 mL/kg/min — demonstrating that rowing can push aerobic capacity to extraordinary levels.
Heart Rate Response
The ACE study found that the treadmill elicited higher heart rates than the rowing machine at the same RPE level. This is partly because running is weight-bearing: blood must flow upward against gravity, reducing venous return and stroke volume, which increases heart rate. On the rower, the seated position facilitates venous return, meaning the heart can pump more blood per beat — resulting in a lower heart rate at the same workload.
Blood Pressure Benefits
Both exercises reduce resting blood pressure with regular training. Rowing may have a slight edge for individuals with hypertension because the seated position and smooth, cyclical motion produce less blood pressure variability during exercise compared to the repetitive impact of running.
The bottom line: both are excellent for heart health. If your goal is purely cardiovascular fitness, either modality will deliver results. The best choice depends on your injury history, joint health, and personal preference — because the exercise you do consistently is always better than the one you skip.
Weight Loss: Which Is More Effective?
Weight loss ultimately comes down to calorie balance: you need to burn more than you consume. While running burns slightly more calories per minute, the weight loss equation is more nuanced than raw calorie numbers suggest. Several factors make rowing a surprisingly effective — and often superior — choice for long-term fat loss.
EPOC (Afterburn Effect)
Rowing's full-body muscle engagement creates a larger EPOC (Excess Post-Exercise Oxygen Consumption) response. Your body continues burning elevated calories for hours after a rowing session as it repairs muscle tissue across your entire body — not just your legs.
Muscle Preservation
During a calorie deficit, your body can break down muscle for energy. Rowing's resistance component helps preserve lean muscle mass, keeping your metabolic rate higher. Runners in a deficit often lose both fat and muscle, which can slow metabolism over time.
Sustainability
The best exercise for weight loss is the one you can do consistently without injury. Rowing's zero-impact nature means you can train 5–6 days per week without the overuse injuries that sideline many runners. Consistency beats intensity for long-term weight loss.
Appetite Regulation
Research suggests that high-impact exercise (running) may increase appetite more than low-impact exercise (rowing) at equivalent energy expenditures. This "compensation effect" can partially offset running's higher calorie burn if it leads to increased food intake.
The verdict on weight loss: Running burns more calories per session, but rowing may produce better body composition results over time due to greater muscle preservation, lower injury risk, and higher training consistency. For individuals who are significantly overweight, rowing is almost always the safer starting point because it eliminates the joint stress that makes running painful and risky at higher body weights.
Time Efficiency
If you have limited time, which exercise gives you more bang for your buck? The answer depends on what you are optimizing for.
| Metric | Rowing | Running | Winner |
|---|---|---|---|
| Calories per minute (moderate) | ~8.5 | ~10.0 | Running |
| Muscle groups trained | 9+ major groups | 4–5 major groups | Rowing |
| Strength + cardio in one session | Yes | No (cardio only) | Rowing |
| HIIT effectiveness (20 min) | Excellent | Excellent | Tie |
| Warm-up time needed | 2–3 min | 5–10 min | Rowing |
| Cool-down / stretching needed | Moderate | Extensive (IT band, calves, hips) | Rowing |
| Total workout time for equivalent benefit | 30 min | 25 min + 10 min strength | Rowing |
When you factor in the total training effect — cardio plus strength — rowing is arguably more time-efficient. A 30-minute rowing session provides both cardiovascular conditioning and muscular endurance work. To get the same combined benefit from running, you would need to add a separate upper-body and core strength session, typically adding 15–20 minutes to your total training time.
Mental Health & Enjoyment
Exercise is one of the most powerful tools for mental health, and both rowing and running deliver significant psychological benefits. However, each offers a distinct experience that appeals to different personalities and preferences.
Rowing Strengths
- Meditative rhythm — the repetitive stroke pattern induces a flow state
- Data-driven motivation — PM5 metrics provide instant, objective feedback
- Weather-independent — no excuses, no seasonal disruption
- Community events — virtual Backyard Ultra and online challenges via ErgUltra
- Low frustration — no traffic, no route planning, no safety concerns
Running Strengths
- Outdoor exposure — sunlight, fresh air, nature (proven mood benefits)
- “Runner’s high” — well-documented endorphin and endocannabinoid release
- Social running — large community, parkrun events, running clubs
- Variety of terrain — trails, hills, urban exploration
- Zero equipment needed — just shoes and a door
Many athletes find that combining both activities provides the best mental health outcome. Running outdoors offers variety and nature exposure, while rowing provides a structured, data-rich indoor training option for days when weather, time, or motivation make outdoor running impractical. Platforms like ErgUltra add a social dimension to indoor rowing that helps combat the isolation often associated with solo erg sessions.

The app connects to your Concept2® PM5 via Bluetooth and captures real-time data including pace, watts, stroke rate, heart rate, and calories burned. Unlike generic fitness trackers that estimate calories from heart rate alone, the PM5 calculates calories from actual mechanical work output, making it one of the most accurate calorie tracking methods available.
Frequently Asked Questions
Is 30 minutes of rowing equal to 30 minutes of running?
Not in terms of raw calorie burn — running burns roughly 10–20% more calories at equivalent perceived effort. However, 30 minutes of rowing provides a full-body workout (86% muscle activation) while running primarily targets the lower body (~50%). When you factor in the total training stimulus, 30 minutes of rowing delivers more comprehensive fitness benefits.
Can rowing replace running entirely?
For general fitness and weight loss, yes. Rowing provides equal or superior cardiovascular benefits with less injury risk. However, if you are training for a running event (5K, marathon), you need to run — the principle of specificity applies. Rowing is an excellent cross-training complement to running, not a complete replacement for sport-specific running training.
Which is better for belly fat?
You cannot spot-reduce fat from any specific area. Both rowing and running create a calorie deficit that leads to overall fat loss. However, rowing may be slightly more effective for improving body composition because it builds muscle across your entire body, increasing your resting metabolic rate. The combination of fat loss and muscle gain often produces more visible results around the midsection.
Is rowing or running better for beginners?
Rowing is generally safer for beginners because it is zero-impact and self-regulating — the resistance matches your effort level. Running at higher body weights or without proper form can lead to overuse injuries. That said, rowing does require learning proper technique to avoid lower back strain. A few technique sessions (or watching Concept2's free tutorial videos) will set you up for safe, effective rowing.
How accurate is the Concept2 PM5 calorie display?
The PM5 calculates calories based on actual mechanical work output using the formula: Cal/hr = (2.8 / pace³) + 300. This is more accurate than heart-rate-based estimates because it measures what you actually produce, not what your body might be consuming. Studies have shown the PM5 to be within 5–10% of laboratory-measured energy expenditure — significantly more accurate than most wearable fitness trackers.
Should I row and run on the same day?
Yes, this is a great approach for hybrid athletes. A common pattern is to run in the morning (when joints are fresh) and row in the evening (when the body is warm and flexible). Alternatively, use rowing as a warm-up before a run, or as a cool-down after. Many Hyrox and CrossFit athletes combine both modalities in the same training session.
