Hopefully when I have trained much longer I will be able to describe what is going on in those exercises.
I have a personal perspective that many people drag out the process of learning these types of skills because they take the view that it takes a "long time" or "many years" to learn these types of skills. It often becomes a self-fulfilling prophecy. Even the most exotic of these manipulations is a skill that can be learned once it is explained and the approach to grasping the skill is outlined. I suggest that people watch these demonstrations and understand that it is a skill that doesn't take forever to learn and think to themselves, "I can do that... show me how and I'll practice and equal your ability in that trick in less than a year". Be positive. It's also very true, in my opinion.
