Any exercise that requires you to match a force with a counter force to maintain stability, will be self regulating. In other words, you can only push or pull to a level that can be stabilized by your own internal force generation.

The opposite of this would be ground reaction forces (GRF). The limitations on force production would be strength issue because you can push through the ground. This is the case with most exercises when the force is moved vertically against gravity. But when the force applied is horizontally or perpendicular to the field of gravity, we don’t get the same benefits from the GRF that we get with a vertical load.

Instead, we must turn to our own internal stability from which to create an anchor point for force generation.

As such, this corrective exercise is an excellent core exercise predominantly for the sagittal plane that does just that. It’s also happens to have some great foot benefits too.
