Actor Ricky Gervais is the latest celeb to join a fitness craze which echoes last summer’s ice bucket challenge.

As part of the Gimme Five challenge, the British comedian donned his gym clothes and trainers and went on a workout spree after being nominated by Aussie actor Hugh Jackman.

He posted a selfie video that shows him weight lifting.

“Hi I am Ricky Gervais and I accept Hugh Jackman’s challenge,” he told his followers on Facebook.

“I couldn’t really understand what he was saying as he doesn’t speak English,” Ricky added before nominating Ben Stiller and Will Arnett to step up to the challenge.

The spike in this apparent new social media fitness craze traces back to US First lady Michelle Obama, aka Flotus, who has been challenging celebrities this week in celebration of the fifth anniversary of her Let’s Move! campaign.

Here are a few celebs sweating it out for Flotus’ campaign and passing on the baton.
