Swimming

Swimming is a full-body aerobic exercise that exerts little pressure on joints and is suitable for people of all ages. Common swimming strokes include freestyle, breaststroke, backstroke and butterfly stroke. When swimming, moving forward in the water through the coordinated movements of the arms and legs can exercise all the muscle groups in the body and improve the function of the heart and lungs at the same time. Before swimming, it is necessary to warm up well to avoid cramps. Beginners should learn the correct swimming strokes under the guidance of professionals, control the swimming time and intensity well, and avoid excessive fatigue.
