Shannen Doherty continues to be an inspiration. The 45-year-old Charmed actress has been very open about her ongoing battle with cancer—from her diagnosis to her decision to shave her head—and we've been seriously impressed by her positive outlook through it all. On Thursday Doherty proved yet again that she's a force to be reckoned with by documenting a post-chemo workout.

"It's the day after chemo as you can see—red face, a little bit puffy from the steroids," Doherty says from the front seat of a moving car in a video she shared on Instagram. "Not feeling too great. I'm really tired. I was nauseous last night and achy. Everything sort of typical after chemo. I would prefer to be laying in bed right now doing nothing, but guess where I'm heading? I'm gonna go work out."

In the caption, the actress explains that she believes how moving helps the healing process and that although it's not always easy, she tries her best to always workout the day after chemotherapy treatments. "Some days are easy workouts and other days I push it but the key is to MOVE!!!" she wrote. "This is for any illness. Obviously, check with your doctor. The road to recovery is paved with all sorts of different material. #beastmode #fightlikeagirl #warrior."

She wasn't kidding either. A few hours later she posted a video of her booty-shaking dance workout with Hollywood trainer Neda Soderqvist.

"Let me tell ya.... shaking your booty is hard work with my Neda who's been helping me move and get toxins out," Doherty wrote alongside the video of her wiggling her hips in the studio. "Yes, I was tired. Yes, I wanted to be in bed but I went and moved and felt way better. Any exercise during illness is good. We can do it!!! #beastmode with @jammalibu #fightlikeagirl #warrior"

Keep up the good work, Shannen!
