Speaker 3 For defence we use a different set of strokes. I only have time to mention three now. The slice comes in under the ball; the block just knocks the ball back; and a lob sends the ball high into the air. You have to be very fit to play fast moving good table tennis, but it is also a good game for relaxation. I don't know of any game more people play. Many youth clubs or entertainment places have table tennis facilities. They are cheap and the game does not depend on the weather. I cannot think of any drawbacks. You would be very unlucky to hurt yourself playing table tennis
