"Cramming all your recommended weekly exercise into one or two weekend sessions is enough to produce important health benefits, a study suggests.
And being active without managing 150 minutes of moderate activity a week was still enough to reduce the risk of an early death by a third.
The findings are based on a survey of about 64,000 adults aged over 40 in England and Scotland."
