The back extension, also called the hyperextension or 45-degree back extension, is a staple for building a strong lower back. You set your hips against the pad of a 45-degree bench, lock your feet under the rollers, then bend forward at the hips and extend back up until your body forms a straight line. It trains your spinal erectors directly, plus your glutes and hamstrings on the way up, and it’s one of the few exercises that works the lower back on its own instead of as a stabilizer for something else.
You might want an alternative for a few reasons. Not every gym has a 45-degree back extension bench, and most home gyms skip it entirely since it takes up floor space for one exercise. Some lifters find that extending the lower back into that top position is uncomfortable, especially if they’re dealing with a disc issue or they’re new to training their erectors and don’t yet have the control to keep the movement in their hips instead of their spine. And once bodyweight back extensions get easy, the bench puts a hard ceiling on how much load you can add without holding a plate awkwardly across your chest.
Here are the 8 back extension alternatives I reach for most, picked for how well they train the same lower back, glute, and hamstring chain, how safe they are for a lower back that doesn’t love loaded spinal extension, and what equipment they actually need. A few of these trade pure spinal extension for a hip-dominant hinge pattern, which is usually the safer and more useful swap for most lifters anyway. I’ll tell you when to use each one and exactly how to do it.

1. Reverse Hyperextension
When to Perform Reverse Hyperextensions
This is the closest swap I’ve got for a back extension. Instead of your torso bending and extending against a fixed lower body, your legs swing down and back up while your torso stays braced, so your lower back works isometrically instead of moving through a big range. Use it when your lower back doesn’t love the loaded top position of a regular back extension, or when you’re building your erectors back up after time off. I usually program it for 3 sets of 12 to 15 reps.
How to Perform Reverse Hyperextensions
- Lie face down on a reverse hyper machine, or the edge of a sturdy bench or table, with your hips at the edge and your legs hanging free.
- Grip the handles or the sides of the bench to brace your upper body.
- Let your legs swing down under control, then squeeze your glutes and hamstrings to swing them back up until your body is roughly in a straight line.
- Control the descent back to the start rather than letting momentum take over.
Equipment: reverse hyper machine, or a sturdy bench or table if you don’t have access to one.
This video from MDFit shows how to perform the reverse hyperextension.
Tips for Reverse Hyperextensions
- Keep the motion coming from your hips, not your lower back.
- Stop the swing once your body is roughly in line. Hyperextending past that just adds strain for no benefit.
- Use a slow, controlled tempo before you add any weight.
- If you don’t have a machine, a stable bench with a partner holding your ankles works in a pinch.
2. Glute-Ham Raise
When to Perform Glute-Ham Raises
This is the toughest bodyweight option on the list, and it hits your hamstrings harder than a back extension while still working your lower back and glutes to keep you braced. Use it once bodyweight back extensions get easy and you want serious posterior chain strength and hamstring size. It’s brutal for anyone new to it, so start with a band-assisted version before you try it strict. I run 3 sets of 6 to 10 reps.
How to Perform Glute-Ham Raises
- Set your feet in the footplate of a glute-ham developer, or have a partner pin your ankles while you kneel on a pad.
- Start with your torso upright and your hips slightly bent, knees at roughly 90 degrees.
- Lower your torso toward the floor under control, resisting with your hamstrings for as long as you can before your glutes and lower back take over.
- Curl yourself back up to the start, driving through your hamstrings.
Equipment: glute-ham developer machine, or a partner and a pad if your gym doesn’t have one.
This video from elitefts shows how to perform the glute-ham raise, including regressions if you can’t yet do a full bodyweight rep.
Tips for Glute-Ham Raises
- Keep your hips extended throughout. Letting them bend turns this into a back extension instead of a glute-ham raise.
- Loop a resistance band around the top of the machine for assistance until you can string together a handful of strict reps.
- Push through your toes at the bottom to keep tension on your hamstrings longer.
- Expect this to be far harder than it looks the first time you try it.

3. Good Morning
When to Perform the Good Morning
The good morning loads your lower back and hamstrings with a barbell instead of just bodyweight, and it’s my pick once a back extension isn’t giving you enough resistance to keep making progress. It’s a hip hinge, so your hips travel back while your torso tips forward, which trains your spinal erectors isometrically instead of asking them to move through the same big range a back extension does. I’d program 3 sets of 6 to 10 reps, staying light while you learn the position, since a rounded back under load here is a fast way to get hurt.
How to Perform the Good Morning
- Set a barbell in a rack at about shoulder height and step under it, resting it across your upper traps like a low-bar squat.
- Unrack the bar and step back, feet about shoulder width apart.
- Brace your core, then hinge at your hips, pushing them back while your torso tips forward and your knees stay soft.
- Lower until your torso is roughly parallel to the floor, or as far as you can go with a flat back, then drive your hips forward to stand back up.
Equipment: barbell and a rack (a safety squat bar works well too if your gym has one).
This video from PureGym shows how to perform the barbell good morning.
Tips for the Good Morning
- Keep a slight bend in your knees the whole set. Locking them out turns this into more of a stiff-leg deadlift.
- Start with just the bar for a few sessions before you add any weight.
- Keep your lower back flat, not rounded, through the whole range.
- Stop the descent the moment your lower back wants to round, even if that’s well short of parallel.
4. Romanian Deadlift
When to Perform the Romanian Deadlift
The Romanian deadlift is the classic hip hinge for training your hamstrings, glutes, and lower back together, and it’s probably the most popular back extension alternative there is. Use it any time you want a heavier version of the same posterior chain work, or when you’re building toward a bigger conventional deadlift and want extra hamstring and lower back volume without pulling from the floor every set. I usually run 3 to 4 sets of 8 to 10 reps.
How to Perform the Romanian Deadlift
- Hold a barbell at hip height with an overhand or mixed grip, feet about hip width apart.
- Brace your core and push your hips back, keeping the bar close to your legs as it travels down.
- Lower until you feel a strong stretch in your hamstrings, usually somewhere between mid-shin and just below your knee.
- Drive your hips forward to stand back up, squeezing your glutes at the top.
Equipment: barbell (dumbbells work as a lighter alternative).
This video from ScottHermanFitness shows how to perform the barbell Romanian deadlift.
Tips for the Romanian Deadlift
- Keep the bar tracking straight down your thighs, not drifting out in front of you.
- Stop the descent once your lower back starts to round, not once you reach a specific height.
- Keep a soft bend in your knees. This is a hinge, not a squat.
- Squeeze your glutes hard at the top instead of leaning back to finish the rep.
For more ways to train this same hip hinge pattern, see our Romanian deadlift alternatives.
5. Deadlift
When to Perform the Deadlift
This is the heaviest, most complete posterior chain option on the list, and it’s my pick when you want to build real strength across your lower back, glutes, hamstrings, and grip all at once. Use it as a main lift once or twice a week rather than an accessory, since it’s too taxing to program the way you’d program a back extension. I’d stick to 3 to 5 sets of 3 to 6 reps for strength, or 5 to 8 reps if you’re chasing size.
How to Perform the Deadlift
- Stand with the bar over your mid-foot, shins close to touching it.
- Bend down and grip the bar just outside your shins, feet about hip width apart.
- Brace your core, drop your hips, flatten your back, and pull the slack out of the bar.
- Drive through the floor to stand up, keeping the bar in contact with your legs the whole way, then reverse the motion to set it back down.
Equipment: barbell and plates (a trap bar is a good substitute if your gym has one).
This video from PureGym shows how to perform the conventional deadlift correctly.
Tips for the Deadlift
- Keep the bar close to your body the entire pull. Letting it drift forward is the most common way to strain your lower back.
- Push the floor away with your legs rather than yanking with your back.
- Reset your brace between reps instead of bouncing the bar off the floor.
- If your lower back rounds before the bar leaves the floor, the weight is too heavy for now.
If pulling from the floor is too much for your lower back right now, our deadlift alternatives guide covers other options, and our rack pulls vs deadlifts comparison breaks down a partial-range option that loads the same lower back and hamstrings with less range to manage.
6. Kettlebell Swing
When to Perform Kettlebell Swings
The kettlebell swing trains the same hip hinge and glute, hamstring, and lower back chain as a back extension, but it’s explosive instead of slow and controlled. Use it when you want a conditioning element alongside the posterior chain work, or as a warm-up to prime your hips before heavier hinging. I like 3 to 5 sets of 15 to 20 reps, or timed sets of 30 to 45 seconds if you’re using it for conditioning.
How to Perform Kettlebell Swings
- Stand with feet a little wider than shoulder width, kettlebell on the floor a foot or so in front of you.
- Hinge down and grip the handle with both hands, then hike it back between your legs like a football snap.
- Drive your hips forward explosively, letting the momentum swing the kettlebell up to about chest height.
- Let it swing back down between your legs and repeat, hinging at your hips each time instead of squatting.
Equipment: one kettlebell.
This video from Brittany van Schravendijk shows how to perform the two-arm kettlebell swing.
Tips for Kettlebell Swings
- Drive the movement with your hips, not your arms. Your arms just hold on.
- Keep your back flat through the hinge. Don’t round it to chase extra height on the swing.
- Start lighter than you think, since the ballistic hip snap takes a few sessions to control.
- Squeeze your glutes hard at the top of each rep instead of leaning back.
For more glute-focused options, see our glute bridge alternatives.
7. Cable Pull-Through
When to Perform Cable Pull-Throughs
This is my pick for anyone whose lower back doesn’t love a barbell in their hands yet still wants to train the hip hinge pattern. The cable keeps tension on your hamstrings and glutes without loading your spine the way a barbell hinge does, which makes it a good option for beginners or anyone coming back from a lower back tweak. I run 3 sets of 12 to 15 reps.
How to Perform Cable Pull-Throughs
- Attach a rope to a low pulley and stand facing away from the machine, straddling the cable.
- Grip the rope between your legs with both hands and step forward until you feel tension.
- Hinge at your hips, pushing them back and letting the rope travel down between your legs.
- Drive your hips forward to stand back up, pulling the rope through until your hands reach hip height.
Equipment: cable machine, low pulley, rope attachment.
This video from Live Lean TV Daily Exercises shows how to perform the low cable pull-through.
Tips for Cable Pull-Throughs
- Keep your knees soft and let your hips do the work, not your knees.
- Don’t round your lower back to reach further down. Stop the hinge once your form breaks down.
- Squeeze your glutes at the top of every rep.
- This is a good exercise for teaching the hip hinge pattern before you load it with a barbell.

8. Superman
When to Perform Supermans
This is the no-equipment option, and it’s also the gentlest exercise on the list, which makes it a solid choice for beginners, for a warm-up, or for easing your lower back back into training after time off. It won’t build much strength once you’re past a beginner level, but it’s a genuinely useful isometric option when a bench or barbell isn’t available. I use it for 2 to 3 sets of 12 to 15 reps, or timed holds of 10 to 20 seconds at the top.
How to Perform Supermans
- Lie face down on the floor with your arms extended out in front of you.
- Brace your core and simultaneously lift your arms, chest, and legs a few inches off the floor.
- Hold the top position briefly, squeezing your glutes and lower back.
- Lower back down under control and repeat.
Equipment: none.
This video from XHIT Daily shows how to perform the superman exercise.
Tips for Supermans
- Keep the range small. A few inches off the floor is plenty, and reaching higher just means using momentum.
- Squeeze your glutes at the top, not just your lower back.
- Keep your neck neutral by looking at the floor a few feet in front of you.
- Add a light resistance band across your back once bodyweight reps stop being a challenge.
Reasons to Choose a Back Extension Alternative
There are a few good reasons to swap the back extension for one of the options above. None of them are a downgrade, and a few of them let you load your posterior chain far past what a bodyweight hyperextension bench ever will.
- You don’t have a 45-degree back extension bench. Reverse hyperextensions, good mornings, and kettlebell swings all cover the same ground with a bench, a barbell, or a single kettlebell.
- Loaded spinal extension bothers your lower back. The Romanian deadlift, cable pull-through, and kettlebell swing train the same chain through a hip hinge instead of asking your spine to move through a big range.
- You want more load than bodyweight can give you. The deadlift, good morning, and Romanian deadlift let you add a barbell once bodyweight back extensions stop being a challenge.
- You need a true no-equipment option. Supermans work anywhere, from a hotel room to a living room floor.
- You’re building your hamstrings, not just your lower back. The glute-ham raise and Romanian deadlift both hit the hamstrings harder than a back extension does.
Muscles Worked by the Back Extension
The back extension and its alternatives above all train a similar chain of muscles that run from your lower back down through your glutes and hamstrings. Some, like the reverse hyperextension and superman, train it through spinal extension. Others, like the Romanian deadlift and cable pull-through, train it through a hip hinge instead. Here’s what’s working on most of these:
- Erector spinae: the primary target, a group of muscles running along either side of your spine that extends your torso and keeps your back from rounding under load. It’s worked directly on the back extension, good morning, and superman, and isometrically on the deadlift and Romanian deadlift.
- Gluteus maximus: drives hip extension on every exercise on this list, and it’s the prime mover on the kettlebell swing, reverse hyperextension, and cable pull-through.
- Hamstrings: biceps femoris, semitendinosus, and semimembranosus all cross the hip and help extend it, and they’re loaded hardest under stretch on the Romanian deadlift and glute-ham raise.
- Multifidus: a small, deep muscle along your spine that stabilizes each vertebra individually. It works on every exercise here, though it’s too small to train directly.
- Adductor magnus: assists with hip extension alongside your glutes and hamstrings, especially on heavier hinge patterns like the deadlift and good morning.
- Forearms and grip: work isometrically to hold the bar or kettlebell on the deadlift, Romanian deadlift, good morning, and kettlebell swing.
FAQs
What’s the closest alternative to a back extension?
The reverse hyperextension. It trains the same lower back, glute, and hamstring chain, and it puts your torso in a similar braced position, just with your legs doing the moving instead of your torso. If your gym has the machine, it’s a near one-for-one swap.
Can I build a strong lower back without a back extension bench?
Yes. Your lower back grows and gets stronger from being loaded through a full range with enough volume over time, and it doesn’t care whether that load comes from a hyperextension bench, a barbell hip hinge, a kettlebell, or your own bodyweight. Any exercise on this list will build your lower back if you train it hard and progress it, whether that means adding weight, adding reps, or slowing the tempo down.
What’s the best back extension alternative for a bad lower back?
The cable pull-through and superman are usually the friendliest, since neither one loads your spine into a deep extended position under weight. If a specific exercise hurts, back off the range of motion before you back off the load, and give your lower back a week or two of lighter work before you try to push it hard again. If pain sticks around past that, see a physical therapist rather than trying to train through it.
What’s the best back extension alternative at home?
Supermans if you have no equipment at all, and kettlebell swings if you’ve got a single kettlebell. Between the two, you can cover your whole posterior chain without ever needing a bench or a barbell. A resistance band anchored under your feet is a solid add too, since it lets you load a hip hinge pattern without any real equipment.
Why do back extensions hurt my lower back?
Usually it’s going too far into the top hyperextended position, adding weight before your erectors have the strength to control it, or moving too fast and letting momentum do the work instead of your muscles. If you get pain there, shorten the range so you stop level with your body in a straight line instead of arching past it, drop the added weight, and slow the tempo down before you try to push the range or load again.
How many lower back exercises should I do per workout?
One is usually enough on a day where you’re also deadlifting or doing Romanian deadlifts, since your lower back already gets worked hard by those lifts before you isolate it further. On a day without heavy hinging, 1 to 2 exercises covering both spinal extension and a hip hinge, like a reverse hyperextension and a cable pull-through, will cover the muscle well without piling on junk volume.
Key Takeaways
If you want the closest one-for-one swap, go with the reverse hyperextension. If your lower back doesn’t tolerate loaded spinal extension well, build your program around the Romanian deadlift, cable pull-through, and kettlebell swing instead, since all three train the same chain through a hip hinge. If you’re chasing raw strength, the deadlift and good morning will let you load far heavier than a back extension ever will. Training at home with nothing but bodyweight, supermans will still keep your lower back working, though you’ll want to add a kettlebell swing or two once you have access to any equipment at all. Pick based on your equipment and how your lower back feels that day, and progress it the same way you’d progress a back extension: more weight, more reps, or a slower tempo over time.
