Mark Wahlberg wants to "challenge people to be the best versions of themselves".

The 54-year-old actor recently premiered his 4AM Club Challenge workout series on YouTube, and Mark has rubbished suggestions that his own rigorous workout routine is just for show.

He told E! News: "I really do this. I'll get up at three o'clock--if I get to bed at a decent time. I always try to get eight hours of sleep. This is my daily routine, and I try to get as much done before I go to work or before I'm getting the kids up."

Mark said the series is less about showcasing his own achievements and more about inspiring others.

He said: "We're trying to share what we do and how we become successful, and we want to challenge people to be the best versions of themselves.

"There'll be a big content component to reward people and give them the recognition that they deserve for what they've accomplished in their fitness journey. And then inspire other people at home who look just like them who don't think it's possible."

Mark ultimately wants to help fans to better themselves.

He said: "It's not about what I'm doing, it's really about what you're doing, challenging people to be the best versions of themselves."

Mark previously explained that he maintains his health "the good old-fashioned way".

Reflecting on the recent rise of weight-loss jabs, Mark told the New York Post newspaper's Page Six column: "To each his own, but I do encourage people to eat right and exercise.

"It's much more [of] a lifestyle change. You'd be surprised what you can accomplish when you're willing to do the work."

Mark is determined to manage his health and wellbeing in the "most sustainable" way.

He advised: "It will give you the longevity."

Despite this, Mark refuses to judge people who do use weight-loss supplements, such as Ozempic and Mounjaro.

The film star said: "Everybody has their own path. I don't knock anybody for making their own choices.

"But I prefer, and I've seen lots of people accomplish amazing things, ordinary people doing extraordinary things on a fitness base, and they're now encouraging other people that look like them. That's what I'm into."
