If you want a strong lower back, there is no better exercise than back extensions (aka hyperextensions). Even stiff-leg deadlifts and good mornings don’t compare. Below, you are going to learn everything you need to know about back extensions and we are going to teach you how to do back extension exercises (and reverse hypers) using a hyperextension bench, regular bench, the floor, and a stability ball, as well as how to do them with bands and a suspension trainer. Not only are all these variations great as they keep your training fresh, but they can target your lower back in different ways. Moreover, you’ll be able to do back extensions at home just as effectively as you can at the gym.
While the hyperextension bench is great, it’s not the only way to do back extensions, as you are going to see...
A hyperextension exercise refers to a back extension using a hyperextension bench. The movement simply involves extending your back from a flexed position. So, with your legs fixed to the hyperextension bench, you flex your spine (bend forward) and then extend your spine to come back up.
How far can your back extend?
The normal range of motion for your spine is approximately 30˚ for extension and 90˚ flexion, so working through this ROM with back extensions is perfectly fine, which means you can extend a little past neutral.
If you have lower back issues, you should consult a doctor before performing low back exercises.
Why is it called a Hyperextension?
Now, it should be noted that calling back extensions on a hyperextension bench just a “hyperextension exercise” is actually a misnomer because the term hyperextension itself refers to extending a joint past its normal range of motion.
With back extensions on a hyperextension bench, you are moving your spine in its normal range, even if you exaggerate the movement a little by extending past neutral.
Remember, your low back (lumbar spine) has around 30˚ of extension, as long as you have normal mobility.
With back extension exercises, sometimes you try to maximize the range of motion for extension, but you will never try to extend it beyond its optimal range. Also, your neck and head are always in a neutral position.
Nevertheless, calling back extensions on a hyperextension bench a “hyperextension” or “hyperextension exercise” is accepted in the fitness world. Essentially, it’s a short way of saying ‘back extension on a hyperextension bench’. Moreover, while you are not actually hyperextending lumbar spine, you are moving it through more extension than most exercises do if you decide to extend past neutral, which can sort of feel like hyperextension.
Note: Hyperextension benches aren’t the only way to do back extensions. There are many ways to do back extensions. You can do back extensions on the floor, on a flat bench, on a stability ball or even using resistance bands and suspension trainers. Below we are going to show you examples of all the ways you can do back extensions, not just back extensions on a hyperextension bench.
The main purpose of a back extension (no matter what you are using) is to strengthen the lower back.
The main muscle targeted with back extensions is the erector spinae. The erector spinae is a long muscle that runs up the entire length of the spine. Obviously, you have one on each side of your spine. The main function of the erector spinae is spinal stability.
The erector spinae itself is comprised of 3 smaller muscles:
So, when doing back extensions, you will be strengthening all of these muscles.
Are back extensions good for glutes?
While the primary target of back extension exercises is the lower back, the movement of flexing your spine will give your gluteal muscles and hamstrings stretching tension, and extending your spine will provide them with contraction tension, which means back extensions ARE good for improving the flexibility and strength of both your glutes and hammies too.
Do back extensions work abs?
Back extensions are not just good for the posterior side of our body, they also activate the rectus abdominis, and transversus abdominis. AND, depending on the variation, they can hit other muscles like the obliques as well.
Other muscles that back extensions work that we have not specifically mentioned are the pelvic floor, multifidus, and even the shoulders!
With back extensions obviously comes a stronger and more mobile back. However, there are other benefits as well.
Here are the overarching benefits of performing back extensions on a regular basis:
Back extensions are absolutely worth doing. They are arguably the best exercise for lumbar strength, which is super important in fitness. A lot of people skip back extensions because they think they get enough development with exercises like RDLs and Good Mornings, but the fact is, back extensions are superior for lower back strength (but not as good for hamstrings). So, if you are an athlete or a weightlifter, then you should definitely be incorporating back extensions into your routine as you would any other specific exercise for a specific muscle group. By doing this, you will see serious improvements in your other lifts. Not only will your overall strength improve, but your low back won’t tire out as easily, which is usually why doing lifts like squats for reps need to be cut short.
You can do back extensions twice a week. Ideally you can get around 6 sets in per week and that’s enough. Be sure to do them after you are fully warmed up.
The reverse hyperextension is like the opposite of a back extension. So, your upper body is fixed and your lower body moves through extension. Reverse hyperextensions (aka reverse hypers) involve extending your hips from a flexed position. With that, you are essentially working all of the same primary muscles: low back (erector spinae*), glutes, and hamstrings.
So, the question one would likely come to is...
While back extensions and reverse hypers activate the same primary muscles, there are some notable differences. Studies show that back extensions have a higher degree of activation of the hamstrings, glutes and erector spinae. One could simply conclude that this makes back extensions better. However, reverse hypers have merit in that they are easier on the lumbar spine as they reduce lumbar flexion via the increase of motion at the hips. What does that mean? Well, for someone with low back issues or someone recovering from an injury, reverse hypers would be the better choice (pending the movement is done in a slow and controlled manner and not with jerky momentum).
As long as you have a healthy lower back, you should have no concern about hurting your back with bodyweight back extensions. The point of back extensions is to strengthen your back so that your back won’t get hurt from more high risk exercises like squats and deadlifts. And remember, you are not actually hyperextending your lumbar spine! It is moving in its normal range of motion.
Overall, as long as you perform back extensions and hyperextensions with good form, you shouldn’t worry about hurting yourself.
Are weighted back extensions bad?
Weighted back extensions are also safe and effective, but you need to have proper form and technique throughout the movement. Moreover, you should gradually increase the weight. For example, if you’ve been doing bodyweight hyperextensions, don’t just jump from that to a 20lb plate. Start performing hyperextensions with 5lbs, then 10lbs, then 15lbs, and so on, just like you would any other exercise. If you do that, then weighted back extensions are great as they will only increase your strength, stability and endurance potential.
There are many ways that you can do back extensions (and reverse hyperextensions). Below, we are going to show you 18 examples of back extension exercises. We have categorized them as follows:
These categories include weighted and non-weighted back extensions.
With everything, you will be able to do back extensions at home, at the gym, at the park, or wherever else you like to workout.
Here are 18 hyperextension exercises that will be highly effective at strengthening your erector spinae, hamstrings, and glutes. Some variations will also activate other muscles not specifically targeted by standard back extensions/hyperextensions.
Back extensions on a hyperextension bench is very basic yet very effective, which is why most people just do back extensions using a hyperextension bench. Every single gym will have one of these, so if you are a gym go-er, this should be a staple in your low back exercise arsenal.
This version of the hyperextension involves keeping your hands behind your head and moving through full flexion. This simply increases the difficulty of the movement and activates the upper back and shoulders more.
It is called the Prisoner Hyperextension because of the way your hands are placed behind your head.
Note: Your neck and head should always remain aligned with your spine. Don’t bend it backward.
Alternative Hyperextension Bench/Machine
Just for reference, your gym might have a hyperextension machine like this, which is ultimately the same thing, albeit a little more difficult.
This version of the hyperextension is a little easier than the previous one as you will have your hands crossed at your chest and you will only lower your upper body down until your legs and torso make a 90˚ angle. This means your spine will remain straight at all times.
Note: You can make this hyperextension exercise harder by holding a weight plate at your chest as seen below.
This is the same as the hyperextension above, but you only have one leg secured. This makes a big difference as it significantly increases the activation of the hamstrings.
Note: You can make this hyperextension exercise harder by holding a weight plate at your chest. However, because you are using just one leg, additional weight is not really recommended. The weight of your body will be enough, at least for quite some time.
The twisting hyperextension targets your obliques to a high degree as well as your spinal erectors.
Note: Your upper body will rotate, but your head and neck will remain aligned with your chest. There should be no reason to twist your neck. The twist will occur at your core.
This is essentially the same as holding a plate when doing a hyperextension. However, the band provides a different kind of tension. The elastic tension means the resistance will increase the more it stretches (so as you raise your body back up, the resistance will continue to increase). This is great as it provides more resistance at the top of the extension (when the movement starts to get easier) and less at the bottom (when the movement is hardest). Moreover, the band requires you to move slowly and controlled during flexion, to resist the band from just pulling you down. This helps to eliminate any jerky or fast motions, which is most common during flexion on a hyperextension. It also increases activation of the targeted muscles.
If you don’t have access to a hyperextension bench or you simply want to try different variations of back extensions, the standard bench can be an effective way to do back extensions. It’s similar to doing back extensions on the floor, but you’ll have more range of motion for flexion.
This is going to work all the same muscles as a back extension on a hyperextension bench.
To do this exercise, you either need someone to hold your feet down OR you can simply lock your feet under the bench with your heels (which will place your thighs on the sides of the bench a little for grip as well). Assuming you won’t have a partner, we will use the latter method in the 'how to' below.
Floor: Don’t have a hyperextension bench or a standard bench? NO WORRIES. Back extensions can be done on the floor with just your bodyweight, and YES, they are very effective.
Back extensions on the floor work all the same muscles as the hyperextension bench. One of the notable differences is you will be raising your feet up as well as you will really maximize extension. Furthermore, you will not be performing spinal flexion, which is good for those who have issues with their low back.
There are three ways you can position your arms. You can use the prisoner position, arms extended in front of you (superman position), or arms at about 45 degrees with your hands next to your head.
Essentially this exercise is a combination of a reverse hyper and a back extension.
Back Extension on Floor (Easy)
This is simply an easier version of the floor back extension. Rather than bringing your legs up, you will just lift your chest off the ground. Also, your hands will be placed down to your sides.
We recommend this for very beginners or people who have back issues or are trying to rehab their lower back.
If you have mini bands, you can wrap them around your legs and arms (or just your legs or arms) and perform the exercise as seen in the pic. This simply helps you to maximize activation of the muscles and it also brings your shoulders, upper back and hip abductors into play to a higher degree.
The stability ball back extension provides more core activation than the other versions we’ve went through because as the name of the product suggests, you need to maintain stability when using it.
With the stability ball, you will get a fair amount of spinal flexion and you can really maximize extension in a safe way thanks to the flexibility of the ball.
Overall, it’s a very unique way to do back extensions and its definitely worth implementing into your routine at some point.
While this exercise is demonstrated using a weight plate, beginners should first do stability ball hyperextensions with just their bodyweight.
Note: Remember, this is a slow and controlled movement. Keep your core tight throughout to maintain stability.
If all you had was a resistance band (41” loop resistance band) you could still do back extensions, and effectively so.
You will be doing back extensions with bands from a standing position. Essentially, the movement is exactly the same as a stiff-leg deadlift. The only difference is the tension will be coming from down and out in front of you rather than directly below you. This places more tension on your lower back.
Note: Move slow and controlled for the entire movement. It’s essentially the same mechanics as a stiff-leg deadlift except you will be slightly exaggerating the extension at the top.
This is definitely not your standard back extension. It will take some time to get the mechanics down for back extension with a suspension trainer. However, it is not a particularly difficult exercise. So, move slowly and controlled and really focus on good form.
Suspension trainer back extensions work your erector spinae, glutes and hamstrings just like any other back extension. With this exercise you can simply come up from the flexed position to neutral or you can lean slightly back with your arms raised overhead at the top of the movement for a little extra spinal extension.
Note: Move slowly and controlled at all times. Don’t rush through the movement.
Now that we have went over all of the back extensions, look go over a several examples of reverse hyperextensions.
The best way to do reverse hyperextensions is with a reverse hyperextension machine as seen in this pic.
However, the vast majority of gyms don’t have this machine. So, we will show you examples of reverse hypers with more accessible tools.
This is like the back extension on a flat bench but instead of having your upper body off the bench, your lower body will be off the bench.
You can also try this same exercise with your legs in a front position, which means they are bent at 90˚ with your heels touching.
If you want more glute activation, try wrapping a fabric mini band around your lower quads and perform the exercise as you normally would, just be sure to press your legs out to maintain tension on the band.
If you want even more range of motion, set the bench to incline! Just be sure that the bench is high quality so you don’t have to worry about it breaking with all the weight of your body on the back rest.
For this exercise, your body will be in a very similar position as the frog reverse hyper on a flat bench. Your feet will just be spread apart. What this exercise offers is additional resistance. So basically it’s just a weighted version of a flat bench reverse hyper. As such, you should save it for when you advance a little more (or if you are already strong, give it a go right away!).
This is the opposite of the stability ball back extension, so your hands will be planted on the floor and your legs will be moving up and down. Like the stability back extension, the stability ball reverse hyper will demand a lot of core stability in addition to the hamstring, glute and low back activation.
This is a great stretching and mobility exercise for your spine. Essentially, you are trying to extend your lumbar spine one vertebrae at a time, so you will be extending back very slowly. Try to reach maximum extension, which is about 30˚.
There’s no need to do back extensions everyday. If you want to strengthen your lower back, then try to do back extensions 2 times a week for a total of 6-8 sets. This should be plenty of volume. The muscles in the lower back are quick to recovery, so you can do them more frequently than bigger muscle groups like the quads or pecs.
It really depends on your split. If you do a body part split (aka bro split) then you can hit a few sets of back extensions on back day and leg day, preferably towards the end of your sessions. If you do an upper lower split, then you may prefer to do them on lower body days because typically lower body days involve less exercises than an upper body day (considering there are less muscles to hit). If you do a PPL split, then you could do them on either pull or leg day. Another option is to do back extensions like you do core exercises. Maybe you simply throw them into any workout at the end of your session with your core exercises. There is no right answer here, but if you hit back extensions one day, then you should give a day or two rest before hitting it again.
As for which back extension exercises, you can switch them up as back extensions are an accessory or assistance lift, not a main lift. So, maybe you choose two of the exercises above and do them for a month then after a month you switch to another two OR maybe you choose 4-8 and you rotate them monthly. Try as many of these as you can and see which one targets the muscles best for you. If an exercise is effective, then use it for a while. Just be sure to add some variety over the course of your training.
