The easiest pattern correction to understand is both hips tilted forward (second pattern) because both sides activate the same muscles to restore the pelvis and torso position. In many cases this lying exercise in combination with a breathing exercise and standing exercise put you well on your way to posture correction.
This exercise activates the inner thigh muscles (adductors), hip internal rotators and the back of the thighs (hamstrings) to pull the pelvis from tilted too far forward, turned out and moved away from the mid-line center of the body back to neutral.
See your PRI Professional to confirm your posture pattern.
