This is the heights of stealing age old Indian practices! In India, we grew up with this as a form of punishment and called this so called exercise as "Baski." I am sure different parts of the country used to call it with different names, but essentially it was a form of punishment to kids who misbehaved. Watch this video to see how modern science is taking this practice and calling it their own technique! I won't be surprised if this is later patented as their technique.
