Hugh Jackman reveals the unique way he’s kept his famously buff body in shape while under lockdown in his New York City apartment during coronavirus pandemic

Hugh Jackman has been hunkered down at his apartment in New York while the city is under lockdown amid the coronavirus pandemic.

And on Tuesday, the Wolverine star revealed how he has kept his famously buff body in tip-top condition during self-isolation.

The 51-year-old shared a video which showed the Hollywood actor running up the stairs in his 15-storey apartment building to get a heart-raising cardio workout.

The Greatest Showman star posted the short clip to Instagram, after tennis champ Roger Federer uploaded a video of him completing tennis drills while self-isolating.

‘Roger, love those trick shots, unfortunately, we don’t have tennis courts at our place in New York City,’ said a panting Hugh as he climbed the stairs in his video.

‘But we have something you guys don’t have which is a lot of this,’ he added while panning out to show the deserted stairwell.

’15 floors baby!’ he concluded the clip with a big grin.

It is unclear if the X-Men star is still staying in his NYC apartment as he was recently seen in The Hamptons with his wife Deborra-Lee Furness, 64, and daughter Ava, 14.

On Sunday, the trio was spotted with their pet pooches, Dali and Allegra, along the beach.

After the family walk, Hugh posted a couple of cute photos of their two dogs.

He captioned one solo image of Allegra while joking that she was ‘social distancing from Dali.

The photo of Dali urged everyone to ‘stay safe’ as much of the world still battles the coronavirus crisis.

Hugh has one upcoming film, Reminiscence, that had been in post-production before Hollywood projects were shut down after the outbreak.

The Sci-fi flick also stars Thandie Newton, Rebecca Ferguson, Daniel Wu, Cliff Curtis and Natalie Martinez.
