DW Sports Fitness was a British retailing and fitness business, founded as a result of Dave Whelan's purchase of 50 JJB Sports fitness clubs with attached retail stores for £83.4 million in March 2009. The business would later encompass more than 140 sites, which included expansion to stand-alone retail stores and stand-alone fitness clubs. In 2011, the business joined buying group Intersport, and began using its name within its facades, and in 2016 it joint-purchased the Fitness First UK business alongside The Gym Group and Greenwich Leisure Limited.
