Physical fitness can help you to live longer, feel healthier and solve life’s problems better. Various activities can help you to keep fit: from running marathons to climbing mountains to lifting weights. For the ordinary non-sporting person without much time to spare, activities like these are not very practical and, to be honest, they are a waste of time. It is much better in my view to spend no more than half an hour every other day in doing exercises. The important thing is to form such a habit so that you don’t say to yourself, "I won’t take the trouble today!" or "I’ll do it later!" If you haven’t got the will to form a habit like this, a sport like tennis might suit you better. The person who takes part in the game with you will help you to remember to play often and you’ll be able to get your exercise outdoors, too.
