Core Concepts of Core

A strong core is critical for athletic performance and injury prevention. I’m probably not telling you anything you haven’t already heard before. Yes, core workouts and the concept of core is widely popular. But what does it all really mean anyways?

What is the Core?

The core is everything other than your arms and your legs. This means that the core encompasses your abdominals, back muscles, shoulder girdle, and hip muscles. When most people hear the word core they probably think of the ever popular six-pack, which while visually appealing, doesn’t even begin to scratch the surface of the core muscles. In fact, there are 29 muscles that act on the spine and the lower back and pelvis region alone.

Wow! Now that’s a whole new perspective. Even with rippling muscles, it only stands to reason that there might be a few muscles deep below the surface still seriously lacking the attention they need. We all know that the body is completely interconnected and that one imbalance can lead to a system break down or injury. Do I have your attention now?

Why the Core Matters?

As I stated above, the core muscles help to prevent injury, but they also help to fuel athletic performance. The core is the center for which force is produced and it is transferred out through your limbs when you exercise. This means that in order for your arms and legs to really produce optimal force you have to have a stable center. Mostly simply put, your quads can be as strong as they want, but with weak glutes you’ll be seriously lacking power.

So, how can we make sure to target each of these muscle groups to ensure ourselves a strong foundation? Follow the guide I’ve made below. Simply pick a couple exercises from each muscle group and you’ve got yourself a well-rounded workout.

Keep in mind that many of these exercises actually work more than one muscle group and of course there is always more to be had. We couldn’t possibly hit every muscle in this one post, these are the basics or focus groups just to get started.
