As an example, if someone has limited mobility at the level of the hip, performing a deep squat is most likely going to involve some degree of compensation. That compensation may show up in any number of places, but identifying the limitations in mobility prior to programming an exercise is critical in developing higher levels of performance.

Collisions occur with every movement we make, that is how we interact with the world.

Elevate the heels and slow the center of gravity, if the toes get elevated we are hitting the accelerator. Both can be useful strategies, but the context determines which activity is most appropriate for the person in front of us.

If a client of mine wants to know whether or not to wear toe spreaders, we take a look at their foot position. If they have a flat foot, and toes are more spread apart, their need for toe spreaders is most likely low. The person with a higher arch and toes close together, or more likely a candidate for toe spreaders with a better outcome.
