Proprioception

Proprioception is the term used to describe the body's awareness of its position in space, and the position of each part of the body in relation to other parts of the body. For instance, it's proprioception that makes you aware that your arm is extended over your head, even though your eyes are closed.

Neural feedback from your joints and muscles is occurring all the time. The feedback is generated through hundreds of thousands of receptors (movement sensors if you like). The brain processes this information for two main purposes:

1. Spatial awareness – so the brain knows where (precisely) all your body parts are in space (not outer space) so regardless of input from other senses your brain can have a "picture" of what you are doing.
2. To generate reactive muscle contractions – the brain activates muscles subconsciously in order to control movement and protect muscles and joints from injury.

The predominant movements of the board whilst riding produce multi-plane feedback to the brain for strong proprioceptive adaptation. Not limited to just foot/ankle the feedback from the knees, hips, trunks and shoulders is also significant. Proprioceptive adaptation is greatest when movements are multi-plane and variation is great enough so as to be unpredictable. Each of these characteristics is inherent in the XT sequences. Unlike other forms of proprioceptive training (such as wobble boards) the XT incorporates multiple body parts into all movement sequences and workouts.
