The agency will promote Roberts’ international chain of gyms and support the launch of an online fitness channel next year. Roberts is also the author of several health and fitness books.
The client is The Academy's sixth new win since it was founded in March by former Mischief duo Mitchell Kaye and Daniel Glover. The agency's clients include The Sun, The Times, Telefonica, American Express and Beagle Street.
Matt Roberts said: "I'm extremely excited and enthusiastic about working with Mitch and Dan, and their team at The Academy. I have a number of key projects that I'm launching or expanding in 2015 and, quite simply, I trust their track record, reputation and approach to deliver the message that each of these great projects deserve."
Kaye added: "We are excited about being an extension of Matt’s award-winning team, and helping him and his brand to achieve even more in the months ahead."
