Rebel Wilson works up a sweat at LA gym as she continues to keep off 80lb weight loss

Rebel Wilson was seen getting in a rigorous workout this week as she continues to keep off her impressive 80 pound weight loss .

The Pitch Perfect star, 44, headed to a Los Angeles gym on Monday, where she was spotted stretching out her back on a stability ball.

The makeup-free actress was dressed comfortably in a black T-shirt, leggings and white sneakers.

Her signature blonde hair was tied up in a ponytail as she stretched her legs on a yoga mat located near several workout machines.

Rebel — who recently celebrated her daughter's birthday — worked up a sweat with her personal trainer inside the exclusive gym facility.

After declaring a 'year of health' in 2020 after struggling with her weight for much of her life, Wilson lost 80lbs and she's been able to keep most of the weight off.

She was inspired to embark on her health journey after a consultation with a fertility doctor, who told her that she would need to improve her health if she wanted to go through with in vitro fertilization.

As part of her game plan, Rebel committed herself to a strict exercise regimen with the help of personal trainer Jono Castano and followed a low calorie, high-protein diet.

She previously told UsWeekly that she had to tackle an emotional eating habit.

'There's no magic fix. I'd been on diets. I've been really good [about] exercising pretty much my entire life. For me, it was the emotional element that I'd never looked at. I'd kind of been, like, 'Emotions...Ugh, I don't want to talk about things,'' she explained.

Rebel reached her 'goal weight' of 165 by the end of 2020 but she has since gained back around 30 pounds.

In a candid Instagram post published in January, Rebel admitted to fans that she had 'lost focus on my healthy lifestyle' due to her hectic work schedule and was feeling 'bad' about herself.

In order to help her curb cravings and maintain her weight, Rebel revealed in March that she tried the type two diabetes drug Ozempic — which is used off-label as a weight loss medication.

'Someone like me could have a bottomless appetite for sweets, so I think those drugs can be good,' she told The Sunday Times .

However, Rebel noted that she no longer takes the medication.

The Aussie actress' gym workout on Tuesday comes days after she and wife Ramona Agruma celebrated their daughter Royce's 2nd birthday.

The toddler — who Rebel and Ramona welcomed via surrogate in 2022 — turned two on Thursday, November 7.

For Royce's special day, the couple hosted a lavish Disney-themed birthday celebration at their Los Angeles home on Friday.

Rebel shared an adorable Instagram photo of herself and Agruma holding up Royce as they showed off her Disney cake that boasted gold candles and icing with miniature decorative princess dolls.

It sweetly read: 'Happy 2nd birthday Royce!'

They leveled up the festivities with a full-size carousel, bringing the infamous parks home, as the youngster sat giggling on a horse.

Royce's birthday comes nearly two months after Rebel and Ramona tied the knot in Italy after almost three years together.

The pair exchanged vows during an intimate ceremony in Sardinia, Italy on September 28.

It was the perfect fairytale location for the couple to exchange vows as they notably holidayed in Porto Cervo, Sardinia, just days after going Instagram official with their romance in 2022.

The Bridesmaids actress and her partner were reportedly supposed to get married in a 2025 beach wedding , but Rebel decided to move up the date.

DailyMail.com exclusively shared the news of their nuptials last month, revealing that the couple were 'thrilled' to be tying the knot.

'Rebel is really excited to be getting married to the love of her life , she is absolutely thrilled,' a source shared ahead of the big day.

The couple first met in 2021 and announced their engagement in February 2023.

Rebel came out in June 2022 and debuted her relationship with Ramona in a sweet post at the same time, sharing a cosy selfie of them alongside some heartfelt words.

'I thought I was searching for a Disney Prince... but maybe what I really needed all this time was a Disney Princess,' she gushed in an Instagram post at the time.

Just days later, Rebel shared a photograph of her and Ramona grinning and holding hands as they holidayed in Sardinia together.
