Herb Jackson - "The biggest problem in designing equipment for Bruce was that he'd go through it so damn fast. I had to reinforce his wooden dummy with automobile parts so he could train on it without breaking it. I had started to build him a mobile dummy that could actually attack and retreat to better simulate "Live" combat, sadly Bruce died before the machine was built. It would have been strung up by big high-tension cables that I was going to connect between two posts, one on either side of his backyard. The reason for the machine was simply because no one could stand up to his full force punches and kicks, Bruce's strength and skill had evolved to point where he had to fight machines. Bruce was very interested in strength training, you could say that he was obsessed with it".
