Myth Busting: Why You Shouldn’t Imprint Your Spine
Should You Imprint Your Spine in Pilates?
Imprinting your spine is something you may be told to do in certain Pilates classes, particularly during abdominal exercises. It involves flattening your lower back into the mat when lying on your back, so that there is little or no gap between your lumbar spine and the floor.
The idea behind imprinting is usually to stop the lower back from over-arching during abdominal work. In theory, this is meant to protect the lower back from strain when the legs are lifted or moving.
However, although the intention is good, repeatedly forcing the lower back flat into the mat is not always the best option. In many cases, it can reduce the quality of the movement, encourage bracing and prevent the deeper abdominal muscles from working effectively.
At Complete Pilates, we generally prefer to teach clients how to find and control their neutral spine rather than relying on an imprinted position.
Why You Should Be Careful With Imprinting Your Spine
Your spine is not naturally flat.
It has three natural curves: one in the neck, one in the mid-back and one in the lower back. These curves help distribute load, absorb force and allow your body to move efficiently.
Your lower back, or lumbar spine, naturally has a gentle curve. This curve is not a problem. In fact, it is part of how the spine is designed to function.
When you imprint, you flatten this curve. If this is done repeatedly or with too much force, it can encourage a tucked pelvis, reduce natural spinal alignment and make it harder to move well.
This does not mean your lower back should be excessively arched during Pilates. The goal is not to push the ribs up or let the back hang into extension. But there is a difference between avoiding over-arching and forcing the spine flat.
Why 'Neutral Spine' Matters
Neutral spine is the position where the natural curves of your spine are present. In lying, this usually means there is a small space between your lower back and the mat.
Neutral is not one fixed shape that looks exactly the same for everyone. Some people naturally have a larger curve in their lower back, while others have a flatter spine. Factors such as anatomy, posture, mobility, pregnancy, injury history and muscle tone can all influence what neutral looks like.
The aim is to find the position where your spine feels supported, your pelvis is not excessively tucked or arched, and your body can move with control.
In Pilates, learning to maintain neutral spine during abdominal work can help you build strength in a way that is more transferable to real life. After all, we rarely move, lift, walk or exercise with our lower back deliberately flattened.
The Problem With Imprinting During Abdominal Exercises
Many abdominal exercises in Pilates involve lifting one or both legs away from the floor. This increases the load on the trunk and pelvis.
If your abdominals are not yet strong enough to control this load, your lower back may start to arch. This is often when people are told to imprint.
However, flattening the spine may not solve the underlying issue. It may simply allow you to perform a harder version of the exercise before your body is ready for it.
This can lead to several problems.
Firstly, imprinting can encourage you to use the more superficial abdominal muscles, such as the rectus abdominis, rather than developing the deeper stabilising muscles. These deeper muscles are important for supporting the spine, pelvis and trunk during movement.
Secondly, imprinting can cause gripping through the hip flexors and glutes. This can reduce movement at the hip and alter the position of the pelvis.
Thirdly, it can create a braced strategy. Rather than learning to control movement with breath, deep abdominal support and good alignment, the body learns to hold and flatten.
Over time, this may make exercises feel more rigid and less efficient.
Is Imprinting Ever Useful?
There may be times when a small posterior pelvic tilt, or a gentle movement towards imprint, is used as a modification or teaching tool. For example, some people with a very large lumbar arch may need to bring their pelvis closer to neutral before they can control an exercise.
There is also the natural event where your spine moves towards imprint because your whole spine is flexing, not because you have forced it. This is particularly important in exercises such as the Pilates teaser or the Hundreds.
However, this is different from aggressively flattening the lower back into the mat.
A good Pilates instructor should be able to assess whether your spine position is appropriate for your body and the exercise you are doing. The goal should be to help you find control, not force everyone into the same shape.
Finding Your neutral Spine In Pilates
Your lower back is strongest and most efficient when it is in its neutral, natural position. That means it is neither excessively arched nor flattened into the mat.
A simple way to explore this is through pelvic tilts.
Lie on your back with your knees bent and your feet flat on the floor. Slowly tilt your pelvis so your lower back gently moves closer to the mat. Then tilt the other way so your lower back arches slightly more. Move between these two positions a few times.
Then try to find the midpoint between the two. This is your neutral.
You should feel that your pelvis is balanced, your ribs are not flaring upwards, and your lower back has a natural, comfortable curve.
This position may feel unfamiliar if you are used to flattening your back, but with practice it can become much easier to control.
What If You Cannot Keep Neutral During Abdominal Work?
If you struggle to maintain neutral spine during abdominal exercises, the answer is usually to reduce the challenge rather than imprint harder.
For example, if lifting both legs into tabletop causes your lower back to arch or your body to brace, start with a simpler version.
Exercises such as femur arcs, heel slides and dead bugs are excellent ways to build abdominal strength while keeping the spine in a better position.
You can also reduce the range of movement, keep one foot on the floor, use props for support or work with Pilates equipment. The trapeze table, reformer and other Pilates machines can provide spring assistance, helping you strengthen your abdominals without overloading your back.
The aim is to build strength gradually, not force your body into an exercise it cannot yet control.
Why Pilates Equipment Can Help
Pilates equipment can be particularly useful if you find abdominal work challenging on the mat.
The springs can support the body, reduce load or provide resistance depending on the exercise. This means you can practise good alignment and control without feeling like you have to grip, brace or flatten your spine.
For example, working on the trapeze table can allow you to practise leg movements with more support. This can help you develop abdominal control while keeping the pelvis and spine organised.
This is one of the reasons equipment Pilates can be so helpful for people with back pain, injury history or difficulty connecting to the correct muscles.
Ways To Exercise Without An Imprinted Spine In Pilates class
If you are struggling to keep your spine in neutral with abdominal work, reduce the challenge. Exercise like femur arcs and dead bugs, for example, are an effective way of strengthening these muscles that won’t require you to flatten your lower back.
Exercising with the support of the Pilates machines, like the trapeze table, is another great way of strengthening your abdominal muscles with a neutral spine.
Back Pain During Abdominal Exercises
If you experience lower back pain during abdominal exercises, it is worth seeking guidance from a clinical Pilates instructor or physiotherapist.
Back pain during abdominal work may happen for several reasons. You may be attempting a version that is too challenging, using your hip flexors too much, lacking pelvic control, holding your breath or not yet having the strength to stabilise the movement.
In a 1:1 setting, an instructor can assess your posture, strength, breathing, spinal movement and exercise technique. They can then adapt exercises to suit your body and help you progress safely.
Pain is not something to push through. It is information that the exercise may need adjusting.
How To Exercise Without Imprinting
If you are used to imprinting, it may take time to feel confident exercising in neutral spine.
Start with simple exercises where you can monitor your position and breathe well.
Good options include:
- Pelvic tilts
- Femur arcs
- Heel slides
- Dead bugs
- Single-leg tabletop
- Supported abdominal work on Pilates equipment
Focus on keeping the ribs soft, the pelvis balanced and the breath flowing. If you notice your lower back arching excessively, your abdominals bracing hard or your neck and shoulders tensing, reduce the challenge.
Good abdominal work should feel controlled and connected, not forced.
Key Takeaways
- Imprinting means flattening the lower back into the mat, often during abdominal exercises.
- Your spine naturally has curves, and repeatedly forcing the lower back flat may reduce movement quality and alignment.
- Neutral spine is usually a better goal, as it allows the body to work with its natural curves and build more transferable strength.
- If you cannot maintain neutral during abdominal work, reduce the challenge, rather than forcing the spine into an imprinted position.
- Pilates equipment and expert guidance can help, especially if you experience back pain or struggle to connect to the right muscles.
Conclusion
Although imprinting the spine is often taught with the aim of protecting the lower back, it is not always the best approach. The spine is designed to have natural curves, and learning to control movement in neutral spine is usually more effective for building strength, improving alignment and reducing unnecessary tension.
If your lower back arches during abdominal exercises, it may simply mean the exercise is too challenging for your current level of control. Instead of flattening the spine, try reducing the load, choosing a gentler variation or seeking guidance from a clinical Pilates instructor.
At Complete Pilates, we focus on helping clients understand their own bodies, find their neutral spine and build strength progressively. Good Pilates should help you move better, not teach you to brace harder.

FAQs
What does imprinting your spine mean in Pilates?
Imprinting your spine means flattening your lower back into the mat when lying on your back. It is often used during abdominal exercises to try to stop the lower back from arching. However, most people now do this as a forced movement and instead brace. Your spine will naturally move towards an imprinted position if you are getting flexion throughout your spine, such as in exercises like teaser or the hundreds. It is important that this position is not a forced one as can put undue stress on. your back.
Is imprinting bad for your back?
Imprinting is not always necessary and may be unhelpful if it is done repeatedly or forcefully. It can encourage bracing, flatten the natural curve of the lower back and reduce movement quality. For many people, learning to work in neutral spine is more effective. A neutral spine is when you maintain the natural curves of your spine in any position. This changes with gravity and the position you are in so is not a fixed posture.
What is neutral spine in Pilates?
Neutral spine is the position where the natural curves of the spine are present. In lying, this usually means there is a small, comfortable space under the lower back rather than the spine being flattened into the mat. These curves change depending on the position you are in and your orientation to gravity. It is about finding your ability to balance your head and ribcage onto of your pelvis and seeing how they respond to each other.
Why does my lower back hurt during abdominal exercises?
Lower back pain during abdominal exercises may mean the exercise is too challenging, your breath is held or your pelvis and spine are not being controlled well. Reducing the difficulty or seeking professional guidance can help with this. You have lots of ways to modify exercises and doing this, rather than forcing your spine into unnatural positions, will ensure longevity and resilience of your spine.
What exercises can I do instead of imprinting?
Good alternatives include pelvic tilts, femur arcs, heel slides, dead bugs, knee hovers and supported abdominal work on Pilates equipment. These exercises can help build abdominal control while maintaining a more natural spinal position.
