Sports - matter. A man chooses which sport he likes, to which section he enroll in and ... pay attention to sports at all! As for me, I think the sport - it's an integral part of each of us. Sport - this is something that brings joy and pleasure (if the person is engaged in it voluntarily). Also, the sport - it's a way of expression, a way to reach certain peaks and uses! Pursuits Sport also strengthens our spine. In training, we also train our lungs. This leads to the fact that our breath is always smooth and rhythmic! I would also like to note that during exercise, we train our heart, it becomes much more resilient! As for me, I like to go in swimming, because it increases efficiency, increases stamina, strengthens the cardiovascular system and the musculoskeletal system.
