A deep dive into abdominal wall compensations
Movement Debrief Episode 120 is in the books. Below is a copy of the video for your viewing pleasure, and audio if you can’t stand looking at me.
Here is the setlist:
- What movement compensations can occur from a concentric rectus abdominis?
- How can the rectus abdominis become eccentrically oriented?
- How does abdominal fat impact movement?
- How does a pooch belly develop?
- What is a diastasis recti?
- How does breathing coaching change with a diastasis recti?
- What breathing would be recommended for diastasis recti during conditioning?
- How can a pooch belly be managed in standing?
- What are umbilical hernias?
- What causes umbilical hernias?
- Should surgery be done?
- What conservative treatments can be given for an umbilical hernia?

Here is a great move to give to a wide infrasternal angle presentation:
If you are dealing with a narrow infrasternal angle, then you’ll want to try this move:
Rectus abdominis compensations
Could you talk about how an overly active rectus abdominis can attempt to posteriorly tilt the pelvis to achieve a stacked position? Is it desirable? How can you tell if someone has overactive rectus? What are the common strategies to mitigate this if it is a problem? What are the negative effects on breathing and rotation, especially for rotary athletes?
Abdominal Fat and Movement
How does abdominal fat impact movement?
Some thoughts on the lower belly pouch, something along those lines, thank you!
As it relates to Postpartum (0-12 months), Diastasis Recti (milder cases), and considering Infrasternal angle types would you change your breath cues temporarily during the drills you prescribe?
Then, assuming the client has ramped up strength properly during postpartum and for the ongoing diastasis recti management, what type of breathing would you generally recommend during metabolic training (running, jumping etc) to avoid coning or incontinence tendencies?
Reducing pooch belly in standing
Do we want to concentrically contract the pelvic floor while standing and walking? I’ll contract it for other activities, but notice my lower abs stick out despite the six-pack abs.
I would like to know everything about the umbilical hernias in adults. What are the potential causes? Is the only possibility to get rid of it by surgery? Can a person be still physically active? What would you recommend?
- A concentrically-oriented rectus abdominis will limit pump handle mechanics and normal sacral nutation (extension, adduction, internal rotation measures)
- Eccentrically orient the rectus by positioning in quadruped (narrow infrasternal angle), sidelying (wide infrasternal angle), OA extension, and reaching with the chest parallel
- Abdominal fat will limit movement options because the ab wall will become too eccentrically oriented to mobilize the abdominal viscera
- A pooch belly occurs in narrow infrasternal angles due to concentric orientation in the thorax and anterior pelvic orientation
- A diastasis recti is caused by an eccentric abdominal wall, and can be improved through restoring ab wall movement options
- If compensations are seen only in standing, activities will need to progress toward standing and higher intensities to manage these changes
- Umbilical hernias can be impacted by an eccentric abdominal wall. Though there is no research to show a cure from exercise alone (surgery can help), exercise may reduce symptoms and potentially recurrence rates.
