HOW THE RESEARCH WAS CARRIED OUT
Researchers from the Mayo Clinic in Minnesota ranked 39 common exercises based on information obtained from the US National Institutes of Health.
The scientists calculated the number of calories burned if a typically obese or overweight person did such activities for one hour.
Results do not take into account the participant's age, sex or speed of movement.
KEY FINDINGS
The results reveal running at a rate of 8mph and skipping burn at least 861, and up to 1,074, calories for every hour of activity.

Yoga appears to be the worst exercise for weight loss, causing a maximum loss of just 228 calories after a 60 minute workout.
Slow walking, bowling and ballroom dancing also fail to make people lean, burning a maximum of 255, 273 and 273 calories an hour, respectively.
In the middle of the list, kayaking, weightlifting and light swimming burn between 400 and 500 calories every 60 minutes.
