Coach feeds easy balls to the player. Player tries to hit drop shots.
At the beginning, players will try to hit too low over the net. Coaches have to emphasise high trajectory because only these balls have chances to drop close to the net and stay there. It doesn't matter how close the ball bounces to the net; what really counts is second bounce because this is the spot where opponent has to run to.
Indoor courts give players less time and less room. Help them sharpen their split step, shorten their swing and stay calm, and winter becomes a season of real progress.
A tiebreak is a short sprint where every point is worth the same as a break of serve. The players who win them are rarely the ones who hit hardest. Here is how to coach the patterns, habits and scoreboard thinking that win the big points.
Most club players practise the serve on its own and then have no idea what to do with the ball that comes back. Serve plus one is the pattern that turns a good serve into a won point.
