Anyone have a son in a gymnastic development group?

My nearly 6 year old DS has been selected to join the development group at his gym club where he currently does recreational classes. It will be for two hours, and it's going to be a trial to see what he's like and if he can cope etc. The coach who runs the boys development group coaches the girls rec group while DS does the boys rec so hasn't really seen DS at work, but he was suggested to him.

Anyway, other than asking my HR department to pay my salary straight to the gym, what else should I expect? What sort of stuff will they do? The girls development class runs the same time as DS's rec class and they look miserable. Constantly trying to do the splits!
