For Sarah Gaines, AMD’15, what began as a blog called Fit University to help college students stay strong and healthy soon attracted a nationwide community. And, thanks to her Northeastern network and the university’s venture accelerator, IDEA, Fit University is now a global phenomenon, with Gaines holding fitness and health events, workshops and retreats around the world. Recently, USA Today invited her to do a Facebook Live workout for that news outlet’s million-plus online followers. Gaines also hosted a Huskies Fitness class for alumni and established Y Society, a forum to support young women’s social and professional development.
