7 TWISTED COBRA
Place prop under sternum and lie face down with legs hip-width apart and right arm under forehead.
STEP 1: Flex leg muscles until knees come up off the floor and push off right arm, lifting left arm straight alongside ear as if trying to touch ceiling with thumb.
STEP 2: Pull shoulders down your back and extend spine, using right arm to help rotate torso to left. STEP 3: Brace and hold 20 to 30 seconds per side, breathing into belly and rib cage. Repeat 3 times on each side.
A strong, functional core is resilient like a rubber band. If your abs are always tense, say from sucking in your belly, you lose
strength and range of motion.
