5 TRX Back Exercises for a Strong, Pain-Free Back + Workout

If your back rounds forward and aches when you lift things, you’ve probably got weak lats.

But strengthening your lats is part of the puzzle for a strong, pain-free back…

Most back routines then ignore your core, legs and hips: the rest of your postural chain that actually protects your spine.

But after coaching over 8,000 people with suspension training…

I’ve seen what happens when you train your back as an integrated system….

So in this post, I’m going to show you:

1. A simple TRX back workout, with a free 4-week unbreakable back plan to put it all together (grab it below)
2. 5 TRX moves that bulletproof your back by strengthening every link in the chain
3. The best TRX lat exercises (your back foundation) for a stronger, wider back, with no pull-ups needed

To start, let me show you the essential muscle group that supports your spine. And it’s not even in your back.

1. TRX Hamstring Exercise

Think of your hamstrings like the foundation of a house.

They’re the muscles at the back of your legs that connect directly to your pelvis.

They hold it stable so your spine can sit in its natural curve.

But when they’re weak, which happens to most people who sit all day, the foundation starts to crack and tilt.

Suddenly…

Your pelvis tips…

Your lower back flattens out…

And your spine has to work overtime just to hold you upright…

That’s why your back hurts even when you’re not doing anything wrong.

So how do you rebuild your hamstring strength foundation?

Let me show you with TRX Hamstring Curls….

https://youtube.com/shorts/Afyx1-yM0zo

1. Start with your feet in the straps and lift your bum off the ground
2. Squeeze your hamstrings hard and drive your heels toward your bum over 2 seconds, imagine crushing a ball between your heels and bum
3. Hold that squeeze at the top for 2 seconds
4. Now here’s the key: slowly lower down…
5. But stop just before your legs straighten. Don’t fully extend, or you’ll lose tension on the hamstring muscles.

Maintaining tension is the number one muscle-building stimulus, so keep it tight and repeat.

Go for 3 sets of 6 – 12 reps

And stretch your hamstrings for 30 seconds after each set.

Now that you’ve fixed the foundation…

Let’s strengthen the deep spinal muscles that hold your spine tall and upright…

2. TRX Back Extension (Erector Spinae) Exercise

Think of your spine like a sailing mast with ropes keeping it upright and stable.

Those ropes are your erector spinae…

Deep muscles that run from your lower back all the way up to your neck.

But when you sit hunched over a computer for hours, these muscles get slack and weak…

Causing you to slouch forward.

Strengthen them, and you’ll have strong internal ropes keeping you tall and upright.

So how do you do that?

Let me show you how with a TRX back extension (or Supermans)…

https://www.youtube.com/shorts/pxyvXWVjojE

1. Face away from the anchor, with the straps over your shoulders and a wide stance.
2. Brace your core tight, like someone’s about to punch you in the stomach, then slowly extend your arms out over 2 seconds until your entire body is straight.
3. Here’s the key part: hold at full extension for 5 seconds. This is where your spinal erectors are really working.
4. Don’t let your hips sag, or your lower back takes the load.
5. Squeeze your abs extra hard to curl back in.

Start with a slight angle, and step your feet back further as you get stronger.

Go for 3 sets of 4–6 reps.

Now that your spinal stability is fixed…

Let’s move to the muscle that activates your body’s natural weight belt…

3. TRX Transverse Abdominis (Front Core) Exercise

Ever tweaked your back just picking up a bag?

That’s your internal 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, this deep muscle should tighten automatically…

Creating a balloon of support around your spine.

But after hours of sitting, it goes dormant.

And your spine’s got no backup support.

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

Let me show you with the plank advancement…

Just holding a plank isn’t enough to engage and strengthen your transverse abdominals.

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

It feels a little strange at first, but stick with it:

https://www.youtube.com/shorts/QjgEe5e-4JY

1. Get into the plank position with your bum just above parallel
2. Squeeze your entire core
3. Then draw your belly button towards your spine and hold it there for as long as you can

Repeat this for 5 sets. Resting for 10 seconds between each one

Now that you’ve reactivated your internal support system…

Let’s strengthen the muscles that control your shoulder blades and rounded posture.

4. TRX Wide Row (Trapezius and Rhomboids)

Your trapezius and rhomboids work like reins controlling your shoulder blades.

Their job is to pull your shoulders back and keep your upper back strong and stable.

But when those reins lose their strength…

• Your shoulders slump forward…
• Your head drops…
• And your neck takes all the strain.

Re-strengthen those reins, and your posture snaps back into place with your chest proud and your head upright.

Try this: stand side-on to a mirror. If your shoulders sit in front of your ears, this one’s for you.

The exercise for this is the TRX wide row (also called the high row).

Let me show you…

https://youtube.com/shorts/dmdK79vlyiI

1. Start at the top, elbows up and pulled back, chest out, with a slight angle.
2. Slowly lower over 2 seconds, then at the bottom, actively push your arms forward to stretch your upper back. Don’t just hang. Control that stretch.
3. Drive your elbows up and out, keeping them level with your shoulders, over 2 seconds, which targets your upper back rather than your lats.
4. Squeeze your shoulder blades together hard at the top, and hold for 2 seconds.

Go for 2–3 sets of 10–15 reps. When your elbows start dropping, the set’s done.

Now that you’ve strengthened your upper back…

Let’s unlock the essential flexibility in your mid-back and take pressure off your lower spine…

5. TRX Thoracic Spine Extensions Exercise

Your thoracic spine area is like the swivel mechanism on an office chair.

It’s supposed to handle all your twisting and turning so your lower back doesn’t have to.

But when it locks up from hours of sitting still, your lower back is forced to twist beyond its natural range.

Which leads to:

• Disc strain
• Muscle spasms
• Sharp pains when you reach or turn

Free up that swivel, and your spine can rotate safely without strain or pain.

So how do you unlock it?

Let me show you with thoracic extensions…

https://www.youtube.com/shorts/pcmFd9LsLwc

1. Set your straps at knee height and kneel down, facing away from the anchor point
2. Extend your arms forward and slowly drive your chest down, creating a gentle arch in your spine
3. Then add a gentle rotation from side to side
4. Hold this for around 20 seconds, breathing deeply and calmly
5. Slowly return to neutral and repeat 5 times

TRX Lat Exercises: Build a Stronger, Wider Back

The 5 moves above strengthen every link that protects your spine.

But your lats are the biggest muscles in your back, and they deserve their own focus.

They run from your armpits down to your lower back and wrap around your sides….

Think of them as your natural back brace, holding you upright and protecting your spine every time you lift.

But hours hunched over phones and desks switch them off.

Your back brace goes weak, your body starts to cave forward, and your lower back picks up the strain.

Strengthen them, and you stand taller and lift with confidence.

And as a bonus, strong lats give you a wider back and that V-shape…

The problem is, most people feel rows in their arms, not their lats. Here’s how to fix that:

• Your hands are just hooks. Your elbows lead. If you feel it in your biceps, loosen your grip.
• Drive your elbows down and back, tight alongside your body, not out wide. Wide elbows hit your upper back.
• Squeeze at the top like you’re crushing a bottle with your back, and hold it for 2 seconds.
• Stretch at the bottom, don’t hang. Push your arms forward to feel your lats lengthen, but keep the tension on.

Here are three row variations that target your lats from every angle…

TRX Low Row (Hammer Grip)

https://www.youtube.com/watch?v=qcbLwuZW1gE

The hammer grip targets the sides and lower sections of your lats, strengthening your back brace where it supports your lower back. It also builds that sought-after V-shape.

1. Grab the handles with a hammer grip (palms facing each other), and start at the top, elbows back, chest out and lats tight, with a slight angle.
2. Lower slowly over 2 seconds, and actively push your arms forward at the bottom to stretch your lats.
3. Drive your elbows down and back, tight alongside your body, to pull up over 2 seconds.
4. Squeeze your lats hard at the top by pulling on the straps, and hold for 2 seconds. Really feel them working. That’s your mind-muscle connection.
5. Don’t yank with your arms, or your biceps take over and your lats get nothing.

Go for 2 sets of 10 reps to start.

TRX Reverse Grip Row

https://www.youtube.com/watch?v=TP3Swv4kd3M

Once the low row feels easy, progress to this. Turning your palms up makes it even easier to keep your elbows tight and feel your lats working.

1. Grab the straps with your palms facing up, elbows pulled back and chest out.
2. Lower slowly over 2 seconds, and stretch at the bottom without hanging.
3. Drive your elbows back and down alongside your body, and hold the top squeeze for 2 seconds.

TRX High-to-Low Row

Your upper lats need a different angle to get them working.

And when they do, your back brace goes from half-built to complete.

But your arm path is everything.

Get it wrong and your arms do the work instead of your lats.

1. Start with your hands high, palms down.
2. Drive your elbows down and back towards your hips.
3. At the top, try to wrap your elbows around the back of your body to really squeeze your upper lats.
4. Slowly lower yourself, driving your hands back up and forward to fully stretch your upper lats.

Go for 2 sets of 10 reps.

Quick tip: your arms usually give out before your lats do. So when you can’t do another full rep, add 3–5 half reps at the bottom.

TRX Lower Back Exercises

Most lower back pain isn’t fixed by training your lower back alone.

It’s about strengthening everything that supports it.

That’s why these moves target your lower back directly:

• Back Extensions (Link 2): strengthen the erector spinae that hold your spine upright.
• Planks with the belly button draw-in (Link 3): wake up your natural weight belt to protect your spine when you lift.
• Hamstring Curls (Link 1): stabilise your pelvis so your lower back doesn’t have to overwork.

If you want to add two more, make it the TRX glute bridge first:

TRX Glute Bridge

Your glutes anchor your pelvis, and when they switch off from sitting, your lower back takes the strain.

1. Set the straps to mid-calf height, and get both feet in the straps.
2. Squeeze your glutes hard to activate them, then drive your feet down into the straps to lift your hips high.
3. Pause at the top for as long as you can, then lower slowly.

Then add TRX Rear Back Twists…

TRX Rear Back Twists

Lifting your kid out of a car seat. Swinging a golf club. Reaching into the back seat for your bag.

They all rely on the stabilisers around your lower back and sides.

When they’re weak, your spine takes the strain instead.

These twists switch those stabilisers back on.

1. Face the anchor, and wrap your hands together around the handles, leaning slightly back.
2. Stand tall, and rotate smoothly through your core from left to right, using your arms as a solid pivot. Don’t swing your arms or hips.
3. You only need a slight angle to feel it. Lean back further week by week.

Go for 1 set of 10 reps to start.

If you already have lower back pain, check with a doctor or physio before starting, begin gently, and stop anything that makes it worse.

TRX Back Workout

Here’s the TRX back workout I use with clients to strengthen the lats, posture and spine. Do it twice a week to start:

TRX Exercise	Sets × Reps
Low Row (Hammer Grip)	2 × 10
High-to-Low Row	2 × 10
High Row	2 × 10
Supermans	3 × 4–6 (5-second hold)
Rear Back Twists	1 × 10

Use the 2-2-2 tempo on every rep (2 seconds down, 2 seconds up, 2 seconds squeeze), and rest 60 seconds between sets.

Sitting all day?

Add thoracic extensions as your warm-up (5 × 20-second holds), and hamstring curls and planks on your other training days, to strengthen the rest of the chain.

But here’s the catch: do these the same way every week, and your back soon stops getting stronger. That’s exactly where most people stall, because they don’t know what to change.

So the free 4-week Unbreakable Back plan builds them up week by week, with supersets and challenger days to keep it fun.

It tells you exactly what to change, and when…

FAQ

Is TRX good for your back?
Yes, it’s one of the best tools for building a strong back. Every pulling exercise makes you control your own bodyweight, so your back muscles, shoulder blades and core all have to work together. And because you can adjust the difficulty just by changing your angle, it’s easy to start gently and build up.

What is the best TRX exercise for your back?
For overall back strength, the TRX Row is the foundation. It builds your lats, the big muscles that support your upper body. For posture, the TRX High Row in this post is the one I’d prioritise, because it pulls your shoulders back and takes the strain off your neck. Pair it with Supermans for your spinal erectors and you’ve covered the key areas.

Can TRX help with lower back pain?
It can help, because weak hamstrings, a dormant core and a stiff mid-back are some of the most common reasons lower backs get sore. That’s why this post trains the whole chain, not just your back muscles. If you already have back pain, though, check with a doctor or physio first, start gently, and stop anything that makes it worse.

Can you build a bigger back with a TRX?
Absolutely. With muscle-centric technique (driving your elbows back, stretching at the bottom and squeezing hard at the top), your bodyweight becomes a serious load for your back. For width, focus on Low Rows and Reverse Grip Rows to target your lats and build that V-taper. See the “TRX Lat Exercises” section above.

What are the best TRX lat exercises?
The TRX Low Row with a hammer grip is the foundation. It strengthens the sides and lower lats that support your spine, and builds that V-shape as a bonus. Add the High-to-Low Row for your upper lats, and the Reverse Grip Row once the low row feels easy. Whichever you do, let your elbows lead and drive them down and back, tight alongside your body, so your lats do the work instead of your biceps.

How often should you do TRX back exercises?
2–3 times per week works well for most people, with a rest day in between. The posture and mobility moves, like thoracic extensions, are gentle enough to do daily if you sit a lot. Consistency matters more than intensity, especially if you’re rebuilding strength after years at a desk.

So now you’ve got the moves that strengthen every link in your back’s support system, from your lats all the way to your spine.

But here’s the thing…

A strong back sitting on weak legs is still half-built.

Because when your legs can’t take the load, guess what picks up the slack every time you lift? Your back.

So check out this post next, and I’ll show you the 15 most effective TRX leg exercises to build strong, bulletproof legs from home.
