I found that there is absolutely nothing that can keep a man in better shape, as well as keeping you ready to move on a split second's notice. You get good at this, and you'll find that you'll see escape routes that no one else would believe, or ways to reach a target that anyone else would think was untouchable. This discipline is a lot more than just a exercise and fun; it changes your entire way thinking. Where other people will see obstacles, even Black walls, you'll soon start to see pathways. You can use to get where you want to go.
