Folio: Rodale just launched its new paid online education platform Rodale U this month and one of its programs, The Transformation Challenge, has already passed the 5,000 sign-up mark. The program was added to the platform just over a week ago and is base-priced at $9.95. The annual Challenge is a three-week program designed to help participants eat healthier and get in shape as the summer months approach. Started in 2013, it was originally facilitated through a free daily email.
