Ahead of the Rolling Stones headlining Glastonbury on June 29, Mick Jagger has revealed that his stamina-building routine includes ballet.

In an interview with Q Magazine, Jagger swears by ballet to help his balance and to keep his 28 inch waist (!) plus he also studies yoga and pilates

He said: "I train five or six days a week, but I don’t go crazy.

"I alternate between gym work and dancing, then I do sprints, things like that. I’m training for stamina."

His routine also includes running eight miles a day, swimming, kickboxing and cycling with his Norwegian personal trainer Torje Eike, who has trained Olympic athletes and national football teams

Jagger is in training for their Saturday night on the main stage at the festival and is even heading down early the night before.

He said: "I've got nothing else to do, and I want to spend some time with my family.

"Will I get hassled? Depends where I go. I think everyone will be pretty laid back."

He added that his brother, Chris lives in Glastonbury: "so I've had a lot of family pressure to play this show".

However he doesn't need his children's help to show him round the site: "I don't need them to show me the cool places to go.

"I'm sure I can find some places of my own that are much cooler!"
