When you think of core muscles, do you envision a pair of six-pack abs?
True, these muscles are included in the core, but it's so much more than that. Our core muscles include the abdominal muscle group, erector spinae, and glutes.
Although glutes are not likely considering part of your core, they attach to your pelvis and are the opposing muscle group of your lower abdominals as they connect at the opposing parts of the pelvis.
The lower rectus abdominus (we will go over what that is in a moment) attaches to the front of the pelvis, and the gluteus attach to the back of the pelvis.
As one contracts, the other really has to contract in kind as they are pulling and supporting each other. This is like any other partnering (agonist and antagonistic) muscle pairing, but we are talking about the core here so that is where our focus will be currently.
Let's break down the different parts of the core muscles and what function they have.
With this knowledge under your belt, you will have a much better understanding as to WHY you would choose to do certain core activities as opposed to others depending on what kind of core you want to build.
