I am fond of sports.  Sports make us stronger and healthier.  Many people do sports, so do I.  I like to swim in the swimming pool and in the sea in the summer.  I also like badminton and volleyball. Cycling is another favourite sport of mine. There are also mental sports, chess for example.  Chess games improve the work of our brain, so this game is very useful too. In winter I prefer skiing.  It is very good to ski in the fresh winter air.  But we must remember that any sport is good if you practise it regularly.
