Stand and push your hand into the crease between

your buttock and the back of your thigh.

Keep your hand in this location as you sit down on a hard

chair. you should feel your sit bone on your hand.

If you don't , tilt your hips back and forth and you should

feel it. Now balance on your sit bones - you will be

leaning much further forward than you usually do ,

and be sitting much taller.
