What is the Alexander Technique?

The Alexander Technique applies heightened self-awareness of posture to change the way one moves and sits. It is taught in a series of lessons, usually private, during which the teacher watches how you stand, walk, sit, and move your body to see where you unconsciously hold muscle tension, said Jill Geiger, a certified practitioner in Newton.
The teacher also places his or her hands on your body to detect areas of tension and guides you, with words and gentle hands, to realign your body to achieve better posture and relieve tension. The lessons cost about $70 each and may or may not be reimbursed by insurance.
