Anti-rotation exercise to strengthen the muscles of the trunk in control of movement while transferring a rotational force.

The muscles of the trunk (or the so-called “core”) work less as active “movers”, but more like active stabilizers of movement. As an external force meets our body and/or as we generate an internal force response the translation of force has to be managed a meaningful way.

Switching steps while moving the bar creates an external momentum which the muscles of our trunk have to answer with a force of equal magnitude.

Maintain a felt length in the spine while actively resisting the momentum of the bar.

Moving the bar contra-lateral to your front foot further cultivates the biomechanical and neuromuscular preconditions of our self (i.e. contra-laterality of gait and stumble-reflex).
