Swimming is a popular aquatic activity that involves moving through water using the body's limbs and sometimes, specific swimming devices. Swimming is considered a low-impact exercise, which can improve cardiovascular health, muscular endurance, and overall fitness. Swimming can be done in different styles, including freestyle, breaststroke, backstroke, and butterfly stroke. Competitive swimming is a popular sport that is featured in the Olympics and other international sporting competitions. Swimming pools, natural bodies of water like lakes, rivers, and oceans, are popular swimming spots. To swim safely, individuals should be skilled swimmers, use appropriate swimming equipment, and follow safety guidelines.
