My reply was YES... it's simple... but not easy.
I say this to all of my patients with back pain because changing posture really is a simple process, but there are 3 things that you absolutely MUST do in order to have good posture, and these things are not necessarily EASY to do:
1. Develop good mobility of the spine and skeletal structure.
2. Improve strength of the muscles that support your spine in good posture.
3. You need to think about it. Consciously reminding yourself to 'sit tall' is a good place to start.
Over time your new posture will become second nature.
Over time your new posture will become second nature.
Again, like I said... SIMPLE, but not easy. Contact a physical therapist or try a POSTURE BELT for Back Pain if you are interested in doing the work to change your posture to prevent or treat back pain.
