I've heard it said that a boxer's shadowboxing is a type of forms training... in a way - I guess you could say that, but to me there's a big difference in the two approaches. That being forms are pre-choreographed and shadow boxing is fluid and spontaneous. If after a person has learned some prerequisite forms, should they then strive to find a way to shadow-box using a logical progression of techniques derived from the forms? If so, do you think that this type of training is beneficial?
