This video is in response to a pair of questions I received from Shailesh. They read:
Hi Doc, at 1.48s You said pump handle movement happens at back as well, so does it mean flexion of thoracic spine ? What about its effects on lumbar spine ? Thank you
Also if you could please explain role of Diaphragm as regard to pump handle and bucket handle movements as to its 3 attachments ? Thk you.
The video discusses the difference between spinal flexion/extension and general expansion during inhalation.
