Rebel Wilson showcases 3 stone weight loss in sizzling underwater bikini snaps

Rebel Wilson has again showcased her impressive weight loss amid her exercise and health drive that's seen her shed an estimated three stone.

The comic actress, 40, took the plunge for a series of underwater snaps shared to her Instagram.

"Don't ever doubt my mermaid abilities," the star joked, who's renowned for her deadpan brand of dry humour.

She pledged 2020 would be her "year of health", and after jetting back to her native Australia just ahead of the country's lockdown restrictions, got on the health train.

Rebel made waves 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.

Since lockdown, she's dedicated herself to a gruelling workout regimen and strict diet that have seen the pounds fall off.

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.
