Swimming is a very good sport for health. But how to swim safe and healthy is another matter. We shouldn't eat too much before eating an hour. If you have swimming goggles, you should bring them and remember to prepare towels and swimwear. Remember to bring some drinks, too. When we get to the pool and the first thing you need to do to prepare for that swim is to boot, we can't forget to start up properly to avoid unexpected cramps. If you can't swim, you can wear life jackets.
