HOW: Get set-up flat on your back with your feet flat on the ground with the knees bent at approx. 90 degrees. While maintaining a flat low back, push into the ground to bridge up and lift your hips off the ground. Your body should create a straight line from your shoulders to your knees. While maintaining the bridge position, slightly tuck your chin and rotate your head to one side and then the other. Slowly lower down after rotating to each side and repeat.
FEEL: You will feel the muscles behind your thigh, knee, hip, and butt muscles working hard with this exercise. You may also feel your core muscles working too, you shouldn't feel your back muscles working hard. Feeling a gentle stretch in the neck is normal, too.
COMPENSATION: Limit excessive arching of your back, keep your hips level with the ground. Do not let your hips drop or rotate.
