London, July 1 Rebuffing speculations about Michael Jackson's ill-health, his trainer and actor Lou Ferrigno has said that the King of Pop was in great shape.

"I'd never seen him look better," the Sun quoted him as saying.

The 'Hulk' star and a bodybuilder Ferrigno was helping Jacko get in shape for his gruelling series of shows at the O2 in London next month.

He insists that he was stunned to see the 'Thriller' hitmaker getting in shape for a massive comeback.

"When he moved he convinced me that he was going to make the biggest come back in history," he said.

"He was great. I trained him on and off for 15 years and when I saw him a few months ago, the way he moved - I'd never seen him look better," he added.

The two-time Mr. Universe insists that Jacko, who was said to have been taking "mountains of medication", "never" said anything about being in pain.

He added: "As a matter of fact sometimes he would be dancing, showing me the moves, between the sets, our exercising, and he convinced me, I said, 'This guy can pull it off'. When I saw him he was not frail."

The actor said that he was left "extremely devastated" by Jackson's sudden death on June 25 (ANI)
