Drills to improve fluidity and timing

What sort of training drills can I use to improve fluidity and timing on intermediate players?

Hi Fabian,

I think the main thing is to get them to put attention on the tension in different parts of their body initially.

Then do a lot of drills where they start with something simple like hitting from one position.  As they start to feel smooth with that, then increase the difficulty by increasing speed or placement options.  They will get more tense again so let them work through that till they stat to feel smooth again.

The most important thing is getting their attention there.
