Spinal Exercises
Flexors: The primary flexor muscles of the spine are the abdominal and the iliopsoas muscles. The psoas muscles connect the low back with the large upper bone of the leg (femur). Both muscle groups pull the spine forward and also influence the curve of the low back. The iliopsoas muscles also flex and adduct the hip.
Rotators: The rotator muscles include the muscles along the side of the spine and the oblique abdominal muscles. These are the abdominal muscles along the side of the abdomen. The rotator muscles of the spine contribute to maintaining posture and the spine curves.
The abdominal muscles are comprised of four groups that are the internal abdominal obliques, external abdominal obliques, transversus abdominis, and the rectus abdominis muscles. There are a total of 8 abdominal muscles: 4 on the right side and 4 on the left side. The rectus abdominus is the most visible muscle lying at the front of the abdomen. Its primary role is to flex the low back (lumbar spine) forward. The other three groups of muscles work together to maintain an increase intra-abdominal pressure and also to help stabilize the lumbar spine. If you have to lift a heavy object, you will contract or tighten your abdominal muscles and hold your breath to stabilize your lumbar spine.
The abdominal muscles are used during the course of the day although the amount of activity is often not enough to condition the muscles to the point where they will help prevent back injury and back pain. The abdominal and back muscles are prone to weakening with age unless they are specifically exercised.
