How many calories does swimming burn?

Swimming is one of the most complete conditioning activities because water resistance forces the whole body to work at once. That usually leads to high energy expenditure, especially when pace and technical demand go up.

Why swimming is popular for fat loss

Swimming combines high calorie burn with low joint impact, which makes it attractive for beginners, heavier athletes and people who need a break from repetitive land-based cardio.

It also trains the upper and lower body together. That full-body demand is one of the reasons why hard swimming sessions can burn as many calories as many running workouts.
