Abs versus Core: What’s the Difference?

Abs “Abdominal Work” and “Core Stabilization”

The field of exercise science is constantly evolving and becoming more complex, making expert terminology increasingly difficult to follow. Even certified personal trainers from organizations like BCRPA, ACSM, ACE, and NSCA must stay updated on the latest medical trends, treatments, and research. So, it’s no surprise that terms like “abdominal work” and “core stabilization” can be easily confused by the average person!

Understand The Distinction Between The Two

A common mistake in the fitness world is assuming that “abdominal work” and “core stabilization” are the same. However, personal training experts agree that this is definitely not the case! Understanding the difference is crucial for both athletes and health-conscious individuals to help minimize—and ideally prevent—future injuries.

So what is the difference, anyway?

Here’s a simple and effective way of distinguishing one exercise type from another:

 “Abdominal work” is a generic phrase used to describe any type of exercise that works mainly the Rectus Abdominus (otherwise known as the washboard abs ) or the Obliques. These common exercises include “Crunches” and “Crunches with a twist” (as they are commonly referred to).

Anatomical “Belt” or “Corset”

Training one’s “core stabilization muscles” however, is a very specific and well thought-out sequence of exercises intended to strengthen the muscles all the way around the spine instead of focusing on the abdominal muscles at the front of the spine alone. These muscles are known as the “Inner Unit” muscles of the Anatomical “Belt” or “Corset” and consist of the following:

• Diaphragm
• Pelvic Floor
• Lumbar Multifidi
• Transverse Abdominus

This is especially important for those of us who live in the Western world, as so many of our jobs are sedentary in nature.  In spite of this disadvantage, by utilizing the proper core stabilization exercises, you can better protect yourself from future harm.
