Fun tasks and individual approach
In our training sessions adults play as eagerly as children. Teenagers are usually more sceptical to play-based activities, but there are other things to keep them engaged. Solving climbing problems takes not only strength and agility, but also a deal of logical thinking. Often, passing a higher-grade climbing problem is impossible without deciphering the idea of it's author. We train in small groups of 6-12 kids, so that the coach has enough attention for everyone, and we try to place children in groups according to their level. But even so there is a lot of inhomogeneity (e.g. by height) so we often split the group into small teams of 2-3 kids , each getting its own task according to their abilities.
