Frequently Asked Questions

How many calories does swimming burn per hour?
Swimming burns 400-700 calories per hour for a 170-pound person depending on the stroke and intensity. Butterfly is the most calorie-intensive stroke (up to 900 cal/hr), while leisurely swimming burns about 250-350 cal/hr.
Which swimming stroke burns the most calories?
Butterfly burns the most calories (MET 13.8), followed by vigorous freestyle (MET 9.8), breaststroke (MET 5.3), backstroke (MET 4.8), and moderate freestyle (MET 5.8). However, most people cannot sustain butterfly for long periods.
Is swimming a good exercise for weight loss?
Yes. Swimming is an excellent low-impact full-body workout that burns significant calories while being easy on joints. It builds cardiovascular fitness and muscle endurance. The water resistance provides a natural form of strength training.
