Nowadays, many places have indoor swimming pools that can be used for a small fee during the cold months when it’s too cold to swim outdoors. When I think back on youth camps, I remember the camp swimming pool. Guess we all remember our high school swimming pool, at least I do. A lot of fun and memorable times occurred at the swimming pool. Swimming can be a great way to keep in shape and stay healthy. For example, it's been shown that swimming frequently can help reduce blood pressure and regulate blood sugar levels in diabetics. Swimming is also a great exercise for your heart and lungs because it requires you to use your large muscle groups.
