Why in step 5 in the All Four Right AIC Pelvic Floor Respiratory Crawl do you exhale through your nose when you exhale through your mouth in the rest of the steps?
For this technique in step 5 you have your right knee and leg close to each other and are left side bent to the left. The exhalation through the nose in this step is to provide more resistance to activate the L abdominals when they are in that position.
