Balancing the Rib to Pelvis Cylinder

The rib to pelvis cylinder is the myofascial cylinder that connects and relates the lower rib cage to the pelvis. This group of muscles include the quadratus lumborum, psoas, all 4 layers of the abdominals, latissimus dorsi , breathing diaphragm , pelvic floor as well as the thoracolombar fascia. When the rib cage is aligned over a neutral pelvis these muscles are positioned for optimal performance. Because the spine is the only boney link between the rib cage and the pelvic this group of muscles have the dual role of being both supportive and flexible.

A few weeks ago one of my instructors at my studio Mongoose Bodyworks NYC ( Yuliya Romanskaya) showed me a wonderful exercise to help reestablish this connection on one side. Let’s call it “Deltiod to Opposite Rib”. Although the repatterning cues are a bit more complex than the name implies it allows ( for me at least) an easy way to remember it.

Let’s imagine that it is the left side (lower rib cage to pelvis) that you are concerned with. Perhaps you have noticed a lack of “connection” or you suspect a tight or inhibited psoas on this side.

foot with bandPlace a light exercise band on the floor and have your client stand on the right end of it, pinning it to the floor. Then have them pick up the band with their right hand so that the band crosses their body.  (Picture is bird’s eye view)

Their right arm should be straight and slightly abducted to start. The action of this exercise is simply to abduct the arm no farther than 90 degrees ( shoulder height) against the tension of the band and return. Without instructions the tendency will be to slightly side bend the spine to the left. However , our goal is to cue the student to not side bend but to support the left side isometrically. This will kick on the obliques as well. Let’s back up a moment and talk about the left side. What you are looking for is any disconnection between the pelvis and lower ribs.

sideview of neutral pelvisLook to see that the pelvis is neutral and that the ribs are not flared. If the upper fibers of the psoas are tight you will see some extension is the thoracolombar junction or right below. If you see this, place your hand on this area and have them breath into your hand and soften and widen the ribs in the front.

Once you’ve help facilitate a centered torso you’ll want to prepare them to stabilize the left side . Cues like ” energy down through the inner leg” , “width and strength through the low rib cage” will prepare their stabilizing muscles.

arm abduction2Now you are ready to abduct the right arm. Cue them to maintain the left side as the right arm upwardly rotates against the tension of the band.
