David Lloyd gyms is the latest to jump on the "Fortnite" bandwagon with its "Emote Royale" classes, in a bid to get kids to "swap controllers for choreography." The classes were designed with the help of a number of 12-year-old "consultants" who ensured the accuracy of the dance moves being taught.
