Is the erector spinae part of the core?
While the abdominals are a significant part of the core strength, there are other muscles that are important as well. These include: Back extensor muscles- anatomically known as erector spinae or spinal erectors, these muscles start at the base of the skull and run all the way down to the tailbone.

- Erector spinae. The erector spinae is a back muscle that extends up your trunk.
- Rectus abdominis.
- Obliques.
- Transverse abdominis.
- Multifidus.
What is Multifidi?
Multifidus is a group of short, triangular muscles that along with the semispinalis and rotatores comprises the transversospinal group of deep back muscles. They are the thickest muscles in the transversospinal group, and are shorter than semispinalis, but longer than rotatores.
What are the erector spinae muscles?
The erector spinae muscles are nine different muscles located at the back that allows various movements from stretching to aerobic back-bends. These nine muscles are divided into three different groups: iliocostalis, longissimus, and spinalis. The erector spinae muscles are often called spinal erectors.
