Dwayne Johnson admits returning to wrestling is ‘incredibly hard’

Dwayne Johnson is talking about wrestling months after he returned to the ring.

The former wrestler admits he felt his body needs alot of work to go back as he attended WrestleMania40 in April.

“It’s incredibly hard,” Johnson, 52, tells PEOPLE at the opening of Cirque du Soleil ‘Auana in Honolulu.

“The training becomes really extensive, and the training camp becomes extensive,” he adds in a statement on Tuesday.

“So, I went [to] training camp for WrestleMania, which was about an eight- to nine-week training camp,” he adds. “It’s really fast, and fortunately, I was able to get through it all.”

Dwayne then spoke about his upcoming projects including Red One and the animated sequel Moana 2.

“Red One is special. It’s our little Christmas movie, as I like to call it, but also on the Moana 2 of it all, it’s really been this incredible global embrace of our Polynesian culture and how really amazing that is,” he notes.

Johnson tells PEOPLE: “So it’s a good time.”
