bag work with no sparring is tae bo, and bagwork with no sparring, and no idea what you are doing is tae bo. it takes more than just knowing how to throw the punch to using these techniques, and trying to use common sense of what you think you are looking at to say you are boxing.
there is more to learning to box than just punch, slip, bob and weave, and conditioning. but most "cross trainers" to "boxing" dont box in a real boxing gym, and they dont go to real boxers to learn to fight. what you will learn from a boxing gym will amaze you, because they have things most martial artist never even think about. and this is why i say dont trust people who taught himself how to box, and why i call it "tae bo". many of the women who do tae bo know how to through a roudnhouse kick and punches, but they really dont know how to fight with those techniques. even they have good form and look like a black belter in their basics. but the martial artist (especially JKD people) have the same understanding of how to box. bruce lee himself did not train with boxers, which you can tell by his performance of his punchings. and instead of going to the source for the informations, they see videos like bruce lee did and said to themself, "this is a jab, this is a cross/hook/uppercut/slip/bob/weave/pivot" and now he thinks he knows how to box. if you want to learn to through punches, then yes, maybe you can teach yourself. but if you really want the juice and the meat of learning to box, you will have to train with someone who fought long enough to show you all the small details of boxing.
so, if you want to learn how to box to add to your weapons, join a boxing gym, and train for at least one year. there is more to it than it looks easy.
