Light jogging is more beneficial than heavy-duty exercise

Jogging may be most beneficial in small doses, a study has concluded.

Scientists tracked the progress of 1,098 healthy joggers and 413 healthy but sedentary non-joggers for 12 years. They found heavy-duty joggers were as likely to die as inactive non-joggers, while “light” joggers had the lowest death rates.

Jogging from one to 2.4 hours a week was associated with the lowest mortality and the “optimal” jogging frequency was no more than three times per week.
