Lower back pain is a breathing and walking problem. There will always be a component of compensatory breathing and compensatory walking that needs to be reduced in order for the back to relax.

Postural Restoration Institute techniques put your body into a position that will allow your back to relax by allowing for appropriate diaphragmatic breathing and pelvic stabilization.

I offer oneonone training as well as online consultations via Zoom. The information can be found here:
