The Dubai Fitness Challenge is in full swing and Sally Mousa's cranking it up in the studio and breaking a sweat. Sally speaks to Phill Robson, Operations Manager & Head Coach at SwitchDXB, Christina Guastella, Co-Founder at NRG Fitness Dubai Marina, Sean Clancy, Co-Founder of KO8 Fitness, and Franky Spencer, Founder of X-Rig. They give Sally workout tips which you can take a look at on our Facebook page. As a new report reveals the mental health benefits of just an hour’s physical activity a week, it seems there is nothing a workout can’t cure. We ask our panel of fitness experts how much is enough and how much is too much?
