Rebel Wilson delights fans as she returns to US after epic lockdown weight loss

Rebel Wilson has her American fans in overdrive after making her return to the States for the first time since March.

The Aussie actress, 40, jetted back Down Under to isolate just before the country's lockdown rules went into place.

But she didn't squander her time, crafting a rigorous workout and diet regimen after vowing 2020 would be her "year of health".

She's since left fans stunned with her Instagram offerings, in which she's been able to show off her incredible three-stone weight loss in a series of flattering outfits.

Snapping a selfie on a boat in New York Harbour, a mask over her face and shades over her eyes, Rebel posed in front of the city's iconic skyline.

And she teased what's to come, after revealing that she'd had to put a number of projects on hold amid coronavirus.

"I love New York so much!" she gushed, "Going to get some amazing work done here this week x."

She also shared a look at her office in the Big Apple, a photo of a Barbie doll hanging on the wall.

The Bridesmaids star made waves earlier this year as she shared a video of herself flipping a tyre, joking that she was "coming for" famously jacked Aussie acting brothers Chris and Liam Hemsworth.

She's also dished out some workout wisdom, like trying to switch up sessions as much as possible - which for Rebel has meant running up and down the stairs of the Sydney Opera House.

Fitness trainer Jono Castano has been at the centre of Rebel's transformation.

He's dished on little tips and tricks that have made a world of difference to Rebel's workouts and nutrition.

Chatting with Yahoo! Lifestyle, the health guru focused on nutrition, and a five-day workout week.

Jono also advised a balanced "supplementation and multivitamins" regime, as well as "recovering well [from workouts]."

He went on to explain that "this includes stretching, sleeping well, making sure you're not stressed etc."

"I think with any type of transformation," Jono continued, "you shouldn't always look at the easiest option, you know, two months is not enough time to be able to change your body.

"My advice is to keep your goals realistic, short and then achieve them, and progress from there."

Of her workouts, Jono dished on Rebel's high-intensity workouts "and then trying to burn as many calories as we can with movements that aren't going to hurt you."

Meanwhile, Rebel explained her own decision to get into shape.

Chatting to an Australian radio station, she told: "Obviously a lot of the TV shows and movies got shut down, so what I was going to do has been delayed so I'm just getting ripped.

"I'm exercising every day. You've got to get on the bandwagon on being ripped.
