The actress has been documenting her wellness journey on social media

Rebel Wilson has called 2020 her 'Year of Health' and recently showed off her shape on Instagram. But a friend says Wilson's desire to get fit is not just about how she looks.

"Her healthy journey is more about how it makes her feel than the physical benefits," says the source. "She has more energy and more confidence, which you can see from her sexier Instagram shots. She's also having fun with new fashion and beauty looks."

The Pitch Perfect star visited Austria's luxury medical detox and wellness center, VivaMayr, last year with friend and TV host Carly Steel. Wilson, 40, continues to practice what she learned there about diet and exercise. She's also working out with her personal trainer up to six times a week. She's been documenting her wellness journey on social media often posting photos of her workouts.

"Both of these things are requiring a daily effort and there’s constant setbacks — but I’m working hard x."
