Abs vs core muscles — here’s why you should know the difference

A woman's abs.

Have you used the terms “abs” and “core” interchangeably or heard them referred to as the same thing? We're here to explain the difference if the terminology feels confusing.

“Abs” refers to the rectus abdominis muscles that run down the front of your stomach and create the six-pack look we’ve come to associate with strength and athleticism. Your core, on the other hand, refers to a collective group of muscles, including the abs, that form around the torso and promote function, stability and movement.
