Players stay on the service lines and rally together in a cross-court direction. Players have to hit all the balls in the air.
Rally from the service line is a good drill to work not only on volleys but also to improve important tennis skills like reaction and consistency. Short distance from each other means that players can't lose focus even for a second so coach should emphasize proper mental approach to achieve desired results.
In this exercise, players work on consistency, control and placement. The coach should tell players to bend knees really low to react faster and be able to respond to low shots. Many juniors make mistake with hitting the volley and straightening legs what results in late next volleys because of the lost rhythm.
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.
