"To create the spiral tension, the anterior aspect of the trunk and arm need to be lengthened. Since the lunge will rotate the pelvis to the left, if the movement is directed at the stance leg (left), a left arm left rotational at overhead swing/reach will be added. A right arm right rotational at overhead swing/reach is added to the same lunge to focus on the lunge leg. The mobility – stability strategy of 3DMAPS is applied to these movements as well."
