Physiotherapists offer training for the deep muscles of your core. These muscles include: 1) Transversus abdominis – the deepest abdominal that wraps around the abdomen between the lower ribs and top of the pelvis. It stabilizes the low back and pelvis and protects the inner organs. 2) Multifidus – a deep muscle located along the back of the spine very close to the midline that works with other muscles to stabilize the low back and pelvis. 3) The pelvic floor – a hammock of muscles that connect the pubic bone at the front to the tailbone and “sitz” bones at the back. There are no recipes for training the deep muscles – speak to your physiotherapist about the right training for your core.
