HOW: Anchor the Kayezen Vector below knee height. Put your right arm through the strap and rotate to your left to work on anti-rotation to your right and vice versa for anti-rotation to your left. The torso strap should come around your body around waist height.
Stand on one leg keeping your center of mass over your base of support.
FEEL: You will feel your hip and trunk working on the side the Vector is anchored into.
COMPENSATION: Avoid leaning sideways to resist the Vector.
