http://www.youtube.com/watch?v=EbmbScZgZD8 what are the similarities that I gathered from this video to produce a champion. 2 ½ hour of training 5 times a week for a total 12 ½ hours a week. parents coaching kids, then taking them to best trainers in world. wanna be the best gotta put the time, the kickboxing trainer who was torturing his students which is boarder line child abuse, we have seen our share or nutty parents/trainers in tennis. And finally,,,,,,,fighters are born not made, are tennis players born to become champions or are they made?
