High center of gravity-- I got a 6X4 post and laid it on the floor. After I got used to walking on it, I turned it on the side and repeated until I could literally play hopscotch.
Afterward I got two large cinder blocks and put the post through the bottom-- practiced, and then moved it to the second hole.
After six months of practicing that while using weights on my wrists and doing warm ups, I moved it to the top. I placed a third brick in the middle to support, but you get the picture.
once you get the hang of maintaining balanced in your hips, you'll be able to feel your center of gravity well enough to catch yourself in most situations.
If you want a vision of the future, imagine a boot stamping a human face...forever" ~George Orwell
