Sarah Michelle Gellar Talks Working Out With Shannen Doherty: 'She Is An Incredible Overcomer'

Sarah Michelle Gellar has opened up about her close friendship with Shannen Doherty and how her workouts are so intense despite her battle with breast cancer.

“It is a regular routine for her,” the 39-year-old entertainer told People Now of Shannen‘s dance cardio classes. “The class is so hard! Honestly I can only do it maybe twice a month. I’m the one on the floor that’s like, ‘I can’t do this anymore! Is this class over? Oh my God, she’s still going!’”
