Our brains are always doing three things.

This is obviously a highly simplified description of the brain, but it’s essentially correct in its broad strokes, and useful for understanding training and for putting the exercises in this book into practice in the right way.

1. The Brain Receives Input From the Body and the Environment

This input comes from receptors, that is, small sensors situated in the layers of our skin, and in our muscles, tendons, ligaments, and even bones. These receptors supply our brain with information about the movement of our limbs and their position in relation to each other. We also have receptors to monitor chemical changes in the body and temperature changes.
