Players are split into two, three or four teams of 4-6 players. This training program contains 3 soccer games. 
If we have two teams, the organization is simple, but in the case of three or four ones, the teams can compete with each other in tournament, in which everyone is playing with everyone.
The main part of the training can take 45-50 minutes and we take care of that the players don't touch the ball too much with head. (It depends on the given age-group.) For this reason, we can change or organize the games in different way.
The goalkeepers can also practice the headers, but if we want to use them in the goals we can change the games.

Players can perform athletic movements, then they can practice the heading with different basic and advanced tasks.
They make stretching and some short sprints to prepare for the training's main part.
