If you’re studying for the NASM CPT exam, low back arches is one of the movement compensations you need to recognize during the Overhead Squat Assessment.

But instead of simply memorizing that the low back arches, it helps to understand why it happens.

Once you understand the movement, the overact...

If you're studying for the NASM CPT exam, you've probably run into one of the most confusing parts of the material:

Which muscles are overactive, and which muscles are underactive?

You'll see these muscle relationships throughout movement assessments, corrective exercise, and questions about movem...

By now, you understand two important concepts. 

First, you know why the knees cave inward during the Overhead Squat Assessment.

Second, you understand which muscles commonly become overactive and underactive.

Now comes the most important question.

How do you actually use that information?

Wheth...

In Part 1, we learned that knees caving inward isn't simply a "bad squat." 

It's a movement compensation.

The body has chosen a different movement strategy because it can no longer maintain ideal alignment.

Now it's time to answer the question every NASM student eventually asks:

Which muscles ...

If you've ever watched someone perform an overhead squat, you may have noticed their knees move inward as they descend. 

NASM refers to this as knees cave in, one of the most common movement compensations observed during the Overhead Squat Assessment.

For many students preparing for the NASM CPT e...

At this point, you know two important things: 

• Why the feet turn out during the Overhead Squat Assessment.
• Which muscles are typically overactive and underactive.

Now comes the final step.

How do you actually use that information?

Whether you're preparing for the NASM CPT exam or assessing ...

Feet Turn Out: The Overactive and Underactive Muscles You Actually Need to Know

If you've already learned why the feet turn out during the Overhead Squat Assessment, you're ready for the next step: 

Which muscles are causing it?

This is where many NASM CPT students get overwhelmed.

The Overhead Squat Assessment: The Foundation of Corrective Exercise 

If you're studying for the NASM Certified Personal Trainer (CPT) exam, there are few assessments more important than the Overhead Squat Assessment (OHSA). It is the foundation for identifying muscle imbalances, recognizing moveme...

Why Section 1 Matters More Than Most Students Realize

When most students prepare for the NASM CPT exam, they focus heavily on anatomy, corrective exercise, program design, and the OPT model.

That makes sense.

Those sections are challenging.

The problem is that many students completely overlook S...

Bringing Everything Together

Throughout this series, we've built a complete understanding of corrective exercise.

In Part 1, we discussed:

• Muscle imbalances
• Altered reciprocal inhibition
• Synergistic dominance
• Arthrokinetic dysfunction

In Part 2, we covered:

• Muscle knots
• Adhesions
• Dav...
