Shoppers in Fargate were stopped in their tracks when a group of young dancers burst into a flashmob.
About 16 dancers from Hype Dance Academy, on Earl Street in the city centre, performed a dance routine which demonstrated the benefits of exercise as part of a healthy lifestyle.
The flashmob was organised by The Gym Sheffield which opened in Gibraltar Street in August.
Leon Mantey, general manager, said: “Somewhat puzzled by the outburst of loud, pumping music and the large group of dancers, a large crowd very quickly gathered. It was the perfect way to let people know that The Gym is here to help them reach their fitness goals.”
