Shannen Doherty shared an Instagram video of herself on Thursday as she headed for a workout just a day after a chemotherapy session.

The 45-year-old actress shot the video from the passenger seat of a moving vehicle as she explained that she believes it's important to keep active despite her battle with cancer.

Shannen put on a brave face, but noted that she was red and a 'little bit puffy' from steroids.

Working out: Shannen Doherty shared an Instagram video on Thursday of herself headed to a workout a day after chemotherapy

The Beverly Hills, 90210 star said she was 'not feeling too great' and was nauseous and 'very achy' - typical after chemotherapy.

'I'd prefer to be in bed doing nothing, but guess where I'm heading? Gonna go work out!,' Shannen said. 

 The actress in the caption further explained her motivation.

'After chemo day. I believe that just moving helps so much in the healing process It's not always easy and sometimes I can't do it the next day but I try to make an effort to get the blood flowing and the toxins out of my body thru working out,' she wrote.

'Some days are easy workouts and other days I push it but the key is to MOVE!!! This is for any illness. Obviously check with your doctor. The road to recovery is paved with all sorts of different material,' she added.

Shannen recently took to Instagram to post tender snaps of her supportive husband of five years Kurt Iswarienko.

'I love you mom': Later on, she spent time with her mother Rosa and said they decided to 'collapse on the couch and watch TV'

She was thankful and philosophical about her cancer battle in the caption.

'This is us now. Life has handed us an interesting card with cancer and although we would both prefer to not be faced with such a terrible disease, we must also search for the good,' she wrote.

She later in the post got a bit analytical about revelations from her cancer battle.

'@kurtiswarienko surprised me by taking me to South Africa. By far the best trip I've ever been on. It was enlightening, inspiring and life changing,' she declared.

'Only kurt would understand me well enough to know that this was the perfect honeymoon trip. As I said before.... I'm lucky. I married my other half, my soul mate,' Shanned added.

Doherty has been documenting her battle against cancer and is nearing the end of her chemotherapy and radiation treatment after a mastectomy in May.

She was diagnosed with breast cancer in March 2015 and it spread to her lymphatic system in 2016.
