Thanks, guys; great suggestions, I really appreciate it.
Lukhas, the game you suggest is what we call 'king of the court'. I like it cos it's quite adaptable, and also, if one player is dominating, the coach can always step in for a turn and dethrone the king
10s talk, some great ideas, thank you! Although I think I'm going to pass on the 'racquet race' game; I don't want to assume liability for any head wounds etc
How do you suggest adapting the games for the different age groups (besides using softer balls and playing from the service line for the younger ones)?
