Transverse Abdominus

Transverse Abdominus

Pictured above is the transverse abdominus muscle. It tightens the space between your ribs and hips and flattens your belly. It works with the other core muscles primarily to stabilize the abdominal region and hold your spine steady while you move your body or lift something. You are not as likely to need to stretch and practice SMR on the transverse abdominus as the oblique muscles. However, be sure to check the PSOAS in particular, as it is EXTREMELY LIKELY to have knots that need attention.

The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others. You can access detail for all the muscles in the body with our Coach membership.
