Bodybuilding.com is an American online retailer based in Boise, Idaho, specializing in dietary supplements, sports supplements, and bodybuilding supplements. It is one of the Internet's most-trafficked health and fitness websites, with over 1 million daily visitors. Aside from its commercial responsibilities, Bodybuilding.com publishes daily editorial content, training plans, and streams live broadcasts of major bodybuilding competitions. It also operates its own fitness-themed social network, BodySpace, with over 2.7 million active members. The success of the website has led to a number of proprietary sports nutrition products and accessories being developed and sold under its name. In September 2015, the CEO and founder Ryan DeLuca stepped down from his role, announcing he would be succeeded on an interim basis by Liberty Media CFO Chris Shean.
