3 TRX Core Exercises That Turn Your Spine Into STEEL

What if just 3 TRX exercises could bulletproof your spine?

Most people do crunches or planks, only hitting surface muscles.

But there are 3 deeper core stabilisers that actually protect your spine…

Developing them creates a spine that’s stable, strong, and injury-resistant from lifting or twisting.

So in this post, I’m going to show you the 3 suspension trainer exercises that target these deep core muscles for maximum, lasting results…

Whether you’re new or already experienced!

To start, let me show you how to strengthen the weak spinal muscles responsible for recurring back pain…

Don’t have time to read the post in full? Then watch the video below to learn the 3 TRX core exercises that turn your spine into STEEL…

1. Complete Spinal Stability

Picture your spine as a stack of Jenga blocks, and each block needs its own tiny shock absorber to keep it stable.

That’s your multifidus

Small muscles that attach to the vertebrae.

Their job is to fine-tune the position of every single spinal joint as you move.

But when you sit at your desk all day these tiny muscles shut down.

So when you do move, each vertebra shifts and wobbles like a loose stack of blocks instead of a solid, stable column.

Leading to recurring back pain.

So how do you strengthen these shock absorber muscles?

Let me show you…

1. Lie on your side with both feet in the straps, then tense your core and slowly lift your hips until you’re horizontal.
2. Now here’s the key: keep squeezing your whole core and keep your head in line with your body (don’t let it drop!)
3. This fires up those deep spinal stabilisers from your neck right down to your hips.
4. Hold for as long as you can.

Now that you’ve strengthened those deep spinal stabilisers…

Let’s target the muscle that acts like your body’s natural weight belt…

2. Lifting Protection

Ever tweaked your back picking up groceries or your kid’s backpack?

That’s your support system failing when you need it most…

Your transverse abdominis wraps around your midsection like a natural weight belt.

When you’re about to lift something, or even sneeze, this deep muscle should tighten automatically.

Creating a balloon of support around your spine.  

But after hours of slouching, it goes dormant.

Suddenly, your spine’s got no backup.  

So, how do you wake up your body’s built-in safety belt? 

Let me show you…

Most people plank and wonder why their back still hurts.

Here’s what they miss…

You’ve got to focus on squeezing your core and THEN drawing your belly button back towards your spine.

This is how you strengthen your deep transverse abdominis

It feels a little strange at first but stick with it….

1. Get into the plank position with your bum just above parallel, then squeeze your entire core to hold it.
2. Here’s the key part: draw your belly button towards your spine.
3. Hold for as long as you can.

Alright, your internal weight belt is activated.

But if the foundation underneath it is weak, the whole thing collapses.

This next move fixes that…

3. Internal Core Control

Think of your pelvic floor like the foundation of a house.

It’s a hammock of muscles stretching from your pubic bone to your tailbone, supporting everything above it.

When you lift something heavy, this foundation should kick in automatically to handle the pressure.

But if it’s weak?

It’s like building a house on a cracked foundation, unstable and risky

So how do you strengthen it?

Let me show you…

1. Lie on your back close to the straps and get the balls of your feet in.
2. Here’s the crucial part: before you lift, engage your pelvic floor (imagine stopping the flow of urine mid-stream—that internal lift).
3. Lock that in, then drive your hips up towards the ceiling.
4. Hold and keep focusing on that pelvic floor engagement for as long as you can.

Now if your job or hobbies involve lots of twisting, like golf, tennis, lifting kids?…

Add this 4th additional move to protect your spine against rotational strains…

4. Rotational Endurance (optional addition)

Your obliques are like your body’s power steering

They control how smoothly you twist and bend to the side.

When they’re strong, every rotation is effortless and precise.

But if your obliques are weak?

It’s like trying to steer a car with broken power steering:

Every turn feels clunky, and your spine ends up absorbing all the stress.

That’s why you sometimes feel that sharp twinge when you twist or bend the wrong way.

So, how do you upgrade your “steering system” and protect your spine?

Let me show you…

1. Get a long length on the straps, lift them above your head so they’re taut, then take a very small step inwards to create a slight angle.
2. Squeeze your whole core and gently push your hips outwards.
3. Here’s the most important part: keep going until you feel a deep stretch down your side, then hold that position.
4. Maintain a strong squeeze on your whole core and drive your hips back up.

You should feel the other side of your core engage to pull your body vertical. That’s your obliques in action.

Here’s the thing…

These 4 moves will protect your spine.
