    The zumba classes are so much fun, great music, routines and amazing people. There's so much love and energy from everyone who attends. Liene is a fantastic inspirational instructor who's always smiling and encouraging. At a fiver for classes I'd challenge anyone to find such good value for money for fitness classes in London
