I was wondering if you cue the short foot on basically every exercise. (for example Split Squat Variations, Single Leg stance, etc.)
What about even just standing still in every day life. As long as the whole foot remains on the ground and we give ourselves a bit of an arch it is good, correct?
The key is to engage a movement, a posture, an exercise that naturally leads to the short foot. If establishing that position is so daunting, a high threshold is warranted, and you probably can even curl the toes. All of this can jumpstart the pattern but all in a progression so that you don’t have to think about it, or aggressively pull that arch up. It should happen reflexively, and it should happen in accordance with other good things happening at the hips, spine, and scaps. All of those distance pieces can drive the short foot in quiet standing.
Here are some excellent options to integrate the short foot from Patrick Ward.
In standing, yes, there should be an arch. There should also be a tripod buttressing the windlass mechanism of the foot creating that arch. The 3 points of the short foot are the sesamoid of the big toe, the 5th met head, and relatively the lateral calcaneus. When that segment is reflexively stable when you engage the floor, there is a lot of firepower available from the rest of the body.
