Potential savings to the UK from more exercise is … £7 billion.

If each adult in the UK did 12 minutes more exercise each day, the country could save £7 billion in NHS treatment costs, welfare, and loss of earnings, said a report by the healthcare charity Nuffield Health and the London School of Economics.

People who do not exercise have almost 80,000 more hospital inpatient visits a year, it said.

Currently, 70% of adults do not meet the target of 150 minutes of exercise a week.
