In 2013, Reebok announced another fitness partnership with Les Mills, a group fitness and team training program in eighty countries in more than 20,000 studios. The agreement included Reebok footwear and clothing integration into Les Mills' fitness programs and media marketing. By July 2013, the red delta sign began showing up on all of Reebok's fitness collections. The brand announced it was phasing out the vector logo and replacing it with the delta sign, making it the company's second logo change in more than 120 years. The delta symbol represents the three pillars of positive self-change including mental, physical and social, as Reebok increases its presence in the fitness industry with yoga, dance, aerobics and CrossFit.
