She also retweeted a picture from Instagram that hardbodynews took of the front page of The Denver Post with the story on her accident and fight to recover. Van Dyken-Rouen replied back with "Thanks, Hardbody News!"

She later tweeted out a photo of her sitting up in her hospital bedfor the first time, with the help of aides and a back brace. "Making progress," she wrote. "First day I sat up. Thank you for all the thoughts and prayers."
