Rebel Wilson shows off weight loss as she completes gruelling workout

We all know that losing weight can be really tough. Shedding the extra pounds you put on during the holidays is certainly no mean feat, and it takes dedication, commitment, and many hours in the gym before you can see a difference.

It can be hard to stay motivated, so you might need someone to inspire you, and to aspire to. If that's the case then you could certainly do a lot worse than Australian actress Rebel Wilson, who has really been working up a sweat recently.

Rebel previously updated her fans about her weight loss in this video:

Don't believe me? Then just check out her Instagram account, where the Pitch Perfect star has regularly been updating her fans and followers all about her workout sessions alongside her personal trainer Jono Castano Acero.

Back in January for instance, Rebel shared a picture of herself jogging at the beach, which she captioned: "Okay so for me 2020 is going to be called 'The Year of Health.'"

On Tuesday, Acero shared a video on Instagram which showed Rebel enduring an absolutely brutal routine, which saw her swinging a gigantic weighted ball on a rope from side-to-side. Acero captioned the clip: "The ball didn’t stand a CHANCE!! Work it gurl @rebelwilson ❤️? @dogpound @acerotrainingseries [sic]"

However, Rebel has been pretty darn modest about her fitness achievements, and in a recent interview, she irreverently claimed that her weight loss was actually due to the extreme heat she endured on the set of Cats.

Speaking with Entertainment Tonight, Rebel stated: "I lost eight pounds (3.6kg) shooting my number in four days. One, because there’s a lot of physicality … but also, they heated up the set very high, to almost 100 Fahrenheit (37.7 Celsius), so that we could never cool down."
