David Hasselhoff likes his chances against The Rock.

It's been 26 since years since audiences first fell in love with the Baywatch crew and their red bathing suits, and ET's Kevin Frazier caught up with Hasselhoff at the Baywatch movie premiere in Miami, Florida, on Saturday night to find out the answer to everyone's biggest question: Who wins a race between The Hoff's Mitch Buchanan in his heyday, and Dwayne 'The Rock' Johnson?

"He could definitely outrun him, but I bet that's about it," Hasselhoff says of his famous character. "I could outrun [The Rock] and out-dive him."

The 64-year-old actor admitted the prospect of matching up to the muscleman in the famous red swim shorts prompted him to hit the gym -- hard.

"I had to do a scene with The Rock and the first thing I did was get in the gym for six weeks," he revealed, adding: "I had to. Because I said, 'If I'm gonna take a picture with that guy -- he's a man and a half, you know? But it was alright, I felt good!"

The new Baywatch movie brings back the beloved characters of Mitch (played by Johnson), Summer Quinn and CJ Parker with a cast of new actors in the roles. But Hasselhoff explains that R-rated movie will have a different tone to the PG-rated television show!

"It's a different movie, you know. When I saw it, I wasn't expecting it to be Baywatch so I really wasn't that unprepared and I liked it," he says. "It was funny, it was different and the fact that it's R-rated, I said, 'Oh, they're kind of going for it.'"
