As far as I know, it was Mr.Chetan Upadhyaya of Varanasi(Satya Foundation) & not the coach John Wright who coined the idea of introducing Yoga amongst the Indian Cricket team. Satya Foundation's talks with Mr. Jagmohan Dalmiya for introducing Yoga had surfaced in the media during the World Cup. Hence you should correct your version.
Its a waste training players with volleyball & yoga! haha Send them to the gym instead to build up their muscles & make them do cardio to lose their fat.Most of them are flabby with paunches.They dont need volleyball & if they are not going to do yoga all their lives,its a waste.
