Why FitPros find the Inner Core Unit confusing to revise

The Inner Core Unit is one section in the Posture and Stability module of the Level 3 anatomy and physiology exam.

Unlike other areas of the posture and stability module, the Inner Core unit is usually a topic that FitPros get wrong; and here’s why…

The term “core” is used a lot in the gym, it is used to make reference to stabilising muscles like the TVA and mobilising muscles like the rectus abdominus.

And this is confusing because it doesn’t differentiate the INNER CORE UNIT from the superficial muscles of the mid-section.

This same terminology can cause some issues on exam day, if you don’t learn the exact muscles that make up the inner core unit and their location.

Leap inside this 7 mins video, it’s taken directly from the old version of our Level 3 Anatomy Revision Mastery Bootcamp so you can feel confident on exam day.

Which 4 muscles make up the Inner Core Unit?

The inner core unit is comprised of four key muscles, which you need to know about for your level 3 anatomy and physiology exam.

These muscles include:

  • The Diaphragm
  • The Pelvic Floor
  • The Multifidus
  • The Tranversus Abdominus (TVA)

These 4 muscles work together to create stability and to protect our spine, ligaments and intervertebral discs.

What is Intra-abdominal pressure?

When the muscles contract they tighten the cylinder which creates a firm column throughout the torso and relieving pressure from the spine itself.

This is called Intra Abdominal Pressure, and pressure is increased by activating the core. An activated core is the same firm “tensed” feeling that you get when you cough or sneeze; the TVA tightens and pulls in, the pelvic floor tightens and the diaphragm contracts to create this hard protective cylinder.

How to explain the location of all 4 muscles

Make sure you are aware of the following wording, in preparation for your anatomy quiz questions

  • Superior = Upper most = Diaphragm
  • Inferior = Lowest = Pelvic Floor
  • Posterior = Furthest Back = Multifidus
  • Anterior = Furthest Forward = TVA

How many questions you will have in your exam

The Level 3 Anatomy and Physiology Exam will usually have 40 multiple choice questions, but this varies so make sure you check with your provider.

With 40 questions total, you can expect there to be 3-5 questions on Posture and Core Stability, including the inner core unit.

But it’s not just about having the knowledge to pass the exam it’s about using this knowledge when training clients.
