Exercise to strengthen axial stability of the spine.

Assume an athletic stance with your knees slightly bend. The elastic band should be held in line with your sternum during the whole sequence.

Traction of the elastic band will result in a lateral translation which has to be met and answered by means of trunk control.

As you step to the side traction of the band increases, hence increasing the lateral perturbatory force. Maintain spinal length and upward orientation.
