Cecile Raynor, founder of Alexander Technique and Thai Yoga of Brookline, is offering free demonstrations of the Alexander Technique at 2 p.m., most Sunday afternoons at Jamaica Pond, in Jamaica Plain. Raynor says the sessions will help people to develop awareness of how to use their bodies more efficiently.

“The technique promotes better posture and mind-body balance, and it can be experienced on the spot,” says Raynor. “This is not a lecture but an experiential event, and a practice that’s helpful for neck, shoulder, back, joint and postural issues.”

Raynor says the Alexander Technique is especially good for walkers and runners. No prior experience with the Alexander Technique is necessary, Raynor notes. “It is a mind-body learning process based on the fact that the balance of the head, neck, and back fundamentally influences the functioning of the whole person,” she says. “It allows every part of our body to do only what it is designed to do.” Sessions will continue through the warm weather.
