More Information about the Rectus Abdominis Muscle
A weak rectus abdominis muscle can
cause problems with certain exercises and increase the risk of lower back
injury. When the rectus abdminis is weak the antagonists, the erector
spinae muscles have to bear more forces which puts the low back at risk of
injury along with the fact that they are allowed to hyperextend further as well.
