The player faces the back fence and imitates serving action. The player's goal is to reach with the racquet as high as possible and touch the fence with the top edge of the racquet.
Low point of contact is a common factor of many serving mistakes. Hitting into the net is a visible confirmation for beginners that point of contact is definitely too low. Players have to learn how to reach up with the racquet to minimize these mistakes.
During this exercise, the player works on high point of contact. Understanding that higher we contact the ball, more clearance over the net we have is a first step to develop good serve. Many players hit with their arm bent, which is an inferior way to hitting with straight arm. Imitation is a good tool to start improvements in a technical area so players should always use free time to do this.
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.
