Anyone remember the old Batman TV series? Kiddies if you don’t know what I’m talking about then look it up on Face Tube. During each episode there would be a dust up between Batman and his adversaries such as the Joker and the Penguin. When Batman landed a knuckle sandwich on the bad guy a caption would come up - ‘WALLOP!’, ‘BIFF!’, ‘SPLAT!’. This is a bit like watching some players warm up in for a tennis match. Straight on court and ‘POW!’, 'BANG!'. Before the match starts, warm up slowly, in the service boxes if necessary with a shortened swing and exaggerate watching the ball onto your racket. Then you can move back and don't forget to practice every shot - including 1st and 2nd serves. It will help. Ah they don’t make telly like that any more – thank goodness.
