Bruce Lee's garage, was filled with many training apparatus, several heavey bags, one that weight 300lbs it was like kicking a marshmallow bigger then you, he also had a round punching bag to perfect punches to the face, and a jabbing pad to develop speed & power of jabs at the eyes. A paper target, to develop a sense of proper application of power against a giving object. He had devices which hit his student's back developed with nonpassive, tensile cushions on springs. Lee had a special wooden dummy constructed, which he had transported from Hong Kong to the States. He said, remember just because you get very good at this supplemental training, it should not go to your head! He felt that this type of training had value and therefore practiced on this equipement daily. If wood dummy work was not apart of his personal development and training why would he have one contructed and shipped here? Yes, actual sparring is the ultimate, and this other training is only a means toward that end. But, also in sparring you should go all out wear suitable protective equipement Then you can truly learn the correct timing and distance for the delivery of kicks and punches on a moving responding opponent.
