How many calories are burnt per hour sitting on an exercise ball?
I have seen a number of 350 calories extra per day being tossed around on internet with no evidence or explanation. I assume thats the max that has been claimed. SO it would be around 45 calories per hour (claimed)...
Does anyone have any evidence/information about this?
p.s. I have read comments/articles on the negative aspects of replacing a chair with an exercise ball. Thats a different question, i am just interested in average calories burnt per hour for male/female.
