Great little article in Natural Health August 2016 about Footballers who do yoga.  Consultant orthopaedic surgeon Simon Moyes says 'An awful lot of premier division footballers are already taking up yoga..'  Because, he says, flexibility and strength are key factors in knee injuries.   Particular fans of yoga are Joe Hart, Rio Ferdinand, David Silva and Ryan Giggs.

I also found this video from a few years ago now which shows why Ryan Giggs is such a fan.
