Swimming (leisurely pace) If you weigh 150 lbs, you can burn approximately 215 calories in 30 minutes. If you weigh 200 lbs, you can burn approximately 285 calories in 30 minutes. If you weigh 250 lbs, you can burn approximately 360 calories in 30 minutes.
Because you burn more calories when you swim faster, covering more distance, it makes sense that the fastest swim stroke has the potential to burn the most calories. Holland says this is the freestyle stroke. But, that doesnât mean you should opt for the freestyle every time you get into the pool. As well as speed, the amount of calories you burn also comes down to duration and frequency, says Holland. âSo if you enjoy the breaststroke more than freestyle, you may swim longer and be more consistent utilizing that stroke, meaning more total calories burned.â
