I remember when reading about Bruce Lee that he incorporated some of his material from the works of the Indian wrestler Gama who was supposed to be a very great wrestler during his time. I was also able to find through Wikipedia that Sushil Kumar, an Indian, won a bronze medal in Beijing in Olympic Freestyle Wrestling.
I’ve been to India before and I think the main problem is that most of the population care very little about athletics and their lifestyles reflect that. I couldn’t find a single track while I was in Hyderabad city, but there were numerous walking parks. Their idea of fitness is to walk around for half an hour because you need to have a certain daily amount of exercise. I spent my time there running around an artificial lake trying not to hit people that were power walking.
