Im going to scan some attachments later, not now as about to wander off to teach. These attachments are pics from Stuart McGills back care book, Ive been back on it, reading up about disorders and how we move from day to day.. its about distinguishing hip flexion from lumbar flexion..sounds technical..maintaining a mild contraction can help ensure sufficient spine stability too.
try this...take a broom or a feather duster, and imagine a big nasty cobweb in one of the top corners of the lounge...get rid of it, (maybe theres one there already!) but stop before you lift your arm, look at your pelvis, your back, as you reach are you in neutral or are you sticking your tailbone too far out, arching your back? even a simple task like this will cause your back to twinge...
