Mechanics

The sooner you understand that your body moves the same way whether you’re holding nothing, a stick, a rock, a knife, or a gun, the sooner you will be able to get more benefit and efficiency out of your training. Yes, there are some differences because of the weight or the shape or the size of whatever weapon you’re working with. But none of them allow you to move your limbs beyond what you can do now, nothing makes you double-jointed or anything like that just because you pick it up. Human bodies work the same way with one weapon as they do with another as far as the human using that weapon goes.

Understanding this properly allows you to pull many useful things from other combative arts into whatever you’re working on right now.
