"He is using Electromagnetic System," Bindra senior told PTI and when asked to elaborate, added, "It is a system where current that is induced into the body, goes directly to the nervous system. It enhances the functioning of nervous system. It is a complex procedure."
As a simulation of sorts, Bindra climbed a 40-feet high 'pizza pole' ahead of the 2008 Beijing Games, which saw him conquer his "fear" and go on to win a historic gold medal.
