I am 75 years old and out of boxing, except to go by one of the gyms occasionally and watch. I enjoy reading people's ideas on new training methods. In fact, I go on YOUTUBE, and have coaches from around the world showing off new techniques. And that's what makes a good fighter or coach. I'm not saying ever thing new works, but in fact those new ideas have broght boxing a long way from chopping wood, pushing cars, and carrying pails of water running up and down hills and steps. Keep thinking folks. It may seem like a screwey idea to others, but if it works...it works.
