Running vs Rowing: What's the Better Workout?

Although rowing involves pushing back with your legs, you also use your arms and shoulders to pull the handlebar back, making it an excellent upper-body workout. "In general, rowing builds muscle mass faster than running", Elmardi says.

One study found that rowing uses nearly 85 percent of the body's muscles, while running is considered a lower-body exercise, meaning it uses fewer muscles overall, says Elmardi. Plus, long-distance running may increase muscle protein breakdown, which slows muscle growth.

While this depends on how hard you're working, if you're putting equal effort into rowing and running, the latter may have a slight advantage for burning more calories, according to Tom Holland, CSCS, author of "The Micro Workout Plan" and "The Marathon Method".

For example, let's say a person weighing 70kg running at a 12-minute per mile pace—which is considered moderate—for one hour burns about 576 calories, according to Harvard Health Publishing. Rowing at a moderate pace burns about 504 calories.

That's not a dramatic difference, but if your main goal is calories burned, Holland says running tends to be the better workout, especially because it's easier to integrate sprinting into the mix. If you do more vigorous running at 6 mph (10 minutes per mile), that's 720 calories per hour.

Bear in mind that the above numbers are estimates. Many factors go into caloric expenditure, such as gender, metabolism and fitness level. The amount of calories you burn during a specific exercise may not be the same as what someone else burns in the same amount of time.

There are plenty of benefits to running, says Holland, including the ability to lace up and run anywhere, but that's not the case for rowing.

"That said, it can be stressful on the joints, especially the knees and hips", he adds. "Rowing is lower impact, so you can have the advantages of getting exercise and getting muscle recruitment without the drawback of stressing the joints".

However, if done incorrectly, rowing can cause issues in the lower back, particularly if you hunch over as you pull, Holland says. But in general, your joints will be more protected in an activity like rowing, which may be especially important if you've sustained an injury.

Because your limbs are moving in opposing directions, running requires a degree of balance and stability that gets stronger over time, according to Rocky Snyder, CSCS, author of the strength-training guide "Return to Center".

In contrast, rowing requires your arms and legs to move bilaterally—in sync—with no demand on balance and only a minor amount of stability. Both balance and stability transfer to plenty of other activities, from yoga to HIIT to team sports. So if you're interested in either running or rowing as cross-training for any of these activities, hop on that treadmill.

If you have time for only one machine, choose the one that fits your goals for that day. But if you have this option regularly, there are many benefits to switching it up, Snyder says.

"If you combine running and rowing on a regular basis—like doing each twice a week—you'll give your body the best of both worlds", he says. "It would at least provide two different means of physical demand that could complement each other".

Rather than splitting up your cardio workout by using both machines on the same day, Holland suggests alternating days. You could run on Mondays and Wednesdays and row on Tuesdays and Thursdays.

If it comes down to filling one more day in your schedule, he has a simple recommendation: pick the one you like to do the most. After all, enjoyment should be a major consideration for your workout, too.
