From correspondents in London, England, 08:31 PM IST

'Incredible Hulk' star Lou Ferrigno is training pop legend Michael Jackson to prepare him for his forthcoming London concerts.

Former Mr. Universe Ferrigno is paying secret visits to the 'Thriller' hitmaker's Los Angeles home to help him prepare for his forthcoming 'This Is It' shows at London's O2 arena that begin July 13, contactmusic.com reported.

'Lou has been visiting Michael to build him up so he can perform his dance routines. But Michael refuses to lift weights. He doesn't want to bulk up,' said a source.

Michael and Lou struck up a friendship two years ago when the singer began using the 57-year-old actor's gym.
