Three (3) Minutes of Exercise For Every Hour Spent Seated Could Extend A Life By 30% - BBC

The decades-old advice of exercising for 30 minutes a day may not benefit everyone, scientists have claimed.
A study has shown that alternatively, three minutes of exercise for every hour spent seated could extend a life by 30%.

Research led by Glasgow Caledonian University found that sitting too long could even "undo" benefits of exercise.
Lead scientists said there was no "one-size-fits-all" approach to physical activity.

The four-year study, published in the British Journal of Sports Medicine, analysed data from six previous studies including more than 130,000 adults in the UK, US and Sweden.
