Pitch Perfect actress Rebel, 41, embarked on a 'year of health' in 2020 and has since lost an incredible 65lbs.
Earlier this year, she opened up about her journey and revealed the one routine she picked up that helped her reach her target weight.

Instead of gruelling workouts and strict dieting, Rebel admitted that "moderate walking" was actually a key factor in helping her shift "unnecessary body fat".
At the start of her transformation, she attended an Austrian health retreat "which flushed out every toxic substance possible in all sorts of crazy ways" - and it was here she learned the benefits of a brisk walk.
"While there I learned that moderate — not even fast-paced — walking is the best way for me to lose unnecessary body fat," she previously told Shape magazine. "The goal was never to be skinny. It was never to fit into a certain dress size. I put in a weight because I needed some tangible thing."
