And from your experience in tennis now with that many years, what makes an injury prevention program work for an athlete like at that level?

It's a really interesting question around those injury prevention programs.

There's so much debate about whether they do actually work or not.

And certainly the evidence is not totally clear.

And I think this is possibly to do with how varied athletic bodies are.

So a one size fits all doesn't necessarily work really well.

Saying that, I think you can make an injury prevention program for an athlete very effective.

And what do you, what would you say private practice teaches you that elite sport doesn't?
