MANCHESTER (MOL): Manchester is the laziest place in Britain with nearly half of residents exercising less than once a month, according to a new study. The country’s increasingly sedentary lifestyle means that by 2030 the average person will use just a quarter more energy in a day than if they had stayed in bed. And Mancunians are in the worst state of all, with 40 per cent doing less than half an hour of exercise a month - classing them as ‘inactive’. By contrast, Wokingham in Berkshire is the most active area, as 82 per cent of residents exercise at least once in every month.
