Swimming vs Walking: Calories Burned Compared (2026)

Swimming burns 204 calories in 30 minutes and 408 calories per hour, while Walking burns 151 calories in 30 minutes and 302 calories per hour. Swimming has a MET value of 5.8, while Walking has a MET value of 4.3.

Calorie burn during exercise is influenced by MET values, body weight, duration, and intensity. Swimming and Walking are both popular low-impact activities, but they differ significantly in calories burned. This comparison highlights the differences in energy expenditure for a 155-pound person.

What Is the Difference Between Swimming and Walking?

Swimming is a full-body workout performed in water, characterized as a low-impact exercise that provides resistance and support. It engages multiple muscle groups, making it an effective cardiovascular activity. Walking is a basic form of locomotion on foot, considered a low-impact exercise suitable for most fitness levels. It can be performed at various speeds and terrains, making it accessible and easy to incorporate into daily routines.

Swimming vs Walking: Calories Burned Side by Side

The following comparison details the calories burned by Swimming and Walking side by side.

Duration (155 lb / 70 kg)	Swimming	Walking
15 min	102 cal	76 cal
30 min	204 cal	151 cal
45 min	306 cal	227 cal
60 min	408 cal	302 cal

Values are for a 155-pound (70 kg) person. A heavier body burns more, a lighter body less, at the same intensity.

Which Burns More Calories, Swimming or Walking?

For burning the most calories: Swimming burns 53 more calories than Walking in 30 minutes and 106 more calories per hour.

For time efficiency: Swimming burns 6.8 calories per minute, while Walking burns 5.0 calories per minute.

For lower-impact exercise: Both activities are low-impact, but Swimming provides additional buoyancy, reducing joint stress.

Tracking Exercise in Nutrola

Calories burned only count toward your goal if you record them. Nutrola lets you log a session of swimming or walking by describing it in your own words by voice or text, by picking an exercise type and intensity, or by entering the calories directly, and on iOS and Android it can sync workouts automatically from Apple Health or Health Connect. Logged workouts sit next to the food you track from a photo, barcode, or voice entry, so calories in and calories out stay in one place. Nutrola is available from EUR 2.50 per month and shows no ads on any tier.

Sources and Method

MET (metabolic equivalent) values are from the 2011 Compendium of Physical Activities (Ainsworth et al.), the standard reference for the energy cost of physical activity. Calories are estimated with calories = METs x body weight in kilograms x duration in hours. Swimming is rated at about 5.8 METs (freestyle laps, moderate) and Walking at about 4.3 METs (brisk, 3.5 mph). Real burn varies with fitness, technique, terrain, and effort, so treat these as close estimates, not exact counts. This is educational and not medical advice.
