Shannen Doherty shared a video with fans a day after receiving chemotherapy for breast cancer.
"After chemo day," she said.
"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.
"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."
