HOW: Anchor the Kayezen Vector below knee height. Put your right arm through and rotate to your left to work on anti-rotation to your right and vice versa to work on anti-rotation to your left. The torso strap should come around your body around waist height.
Set up lying on your stomach with forearms underneath you. Push through the feet and the forearms to lift yourself up into a straight line to assume a plank position. Lift one leg up towards the ceiling and lower. Repeat on the other side.
FEEL: You will feel your hip and trunk working on the side the Vector is anchored into. You will also feel the shoulder working closest to the anchor.
COMPENSATION: Avoid leaning sideways to resist the Vector.
