An article about my favorite sport

Let's swim!

Swimming is one of the best and cheapest sports; you only need a swim suit, a pair of goggles and a cap and you can start.
This is a kind of sport which allows you to move every part of your body. I have been tried it recently and I am always keen to keep going on.
When you are in the swimming pool, your body goes and your mind stops thinking about life problems and worries. That is why I really enjoy this sport, because you can totally relax in the water.
I am an amateur of swimmer so I do it twice a week. I do not pretend to be athletic but I am satisfied with the exercises I have to do.
On the other hand, I would like to have started swimming since when I was a baby in order to have had more confidence. Despite that, I am quite happy to do it.
Those who would like to take up swimming should to sign up into for a course in at any public pool.
Swimming motivates you to do your best, especially when you see kids going like dolphins. In addiction, this sport is important for everybody because in any dangerous situation you will not end up drowning but because you learn to control anxiety and breathing.
I would suggest that everybody does this wonderful sport.

Swimming is very good exercise, and a useful skill! :)
