Players start from 4:4 and play the best of 5 sets.

Variations:

• Best of 3 (if you don't have a lot of time)
  
• Players play tie breaks – the best of 3 (5)

Benefits:

• Players don't waste time in practice playing points at 1:1 and 15:15. Most of them don't realize the importance of those points and play them too carelessly. Before they mature enough and start listening to the coach, you may present them with these situations which automatically put them in a focused state of mind since every point is important. When they play the best of 5, they have played focused and fighting tennis for 30 or 60 minutes. It starts becoming automatic.
• Players learn how to approach these situations since they play them more often. They can learn from their mistakes and try a different approach to finishing the set maybe 10 minutes after the first type of play (only baseline, defending, …) did not work. Players can make these mistakes in their matches but then they forget and try it next week again. They can't change their approach in the tournament since they have already lost.
