Yoga will keep David Beckham fit to play top-level football well into his forties - so he hopes.
The footie hunk, 35, fell in love with the workout after a one-on-one lesson with the technique founder Bikram Choudhury last year.
And he has become so addicted to the increasingly popular spiritual exercise that he's been selling its benefits to Hollywood pals Tom Cruise, 48, and Will Smith, 41, and his team-mates.
"Kareem told Beckham how regular Bikram yoga sessions would help heal his body, relax his mind and help him carry on playing football for years to come.
"At first David was sceptical it would really make a difference to his body but after a one-on-one session David instantly fell in love with the technique and has been doing it ever since," said the source.
Beckham's football career looked in tatters after missing this year's World Cup with a ruptured Achilles tendon.
But the sporting hero has vowed to fight back to full fitness and make his 116th appearance for his national team with help from Bikram.
"David thinks Bikram yoga has really helped him get his fitness and focus back," a source said.
"He is determined to play top- level football until he's past 40 and he is also adamant his international career is not over," the source added.
