Corsets and their Effect on Muscle Tone, Sculpting & Flexibility

Corseting obviously affects many parts of the body, some systems more obviously than others. One of the more obvious parts that corsetry affects are the underlying core muscles – almost every week, someone asks me if corsets have caused any muscle weakness or atrophy in my core. I would argue that my core has only improved its strength since beginning tightlacing, because it’s made me more conscientious about my posture and muscle tone.

Can Corsets Cause Muscle Atrophy? Can Corsets Worsen your Posture?

If you wear your corset 23 hours a day, 7 days a week (taking it off only to shower and change), it is true that you may experience muscle atrophy, especially in your oblique muscles. Those who do experience atrophy may notice that they get fatigued easily when standing unsupported by their corset for long periods of time. However, nobody has ever flopped over at the waist or snapped their spine in half, from my research. This scenario is simply not realistic.

The risk and amount of atrophy depends on how long and how tight you wear your corset. If you’re wearing your corset with more than a 4-6″ reduction, it’s more likely that the corset will encourage muscle stretching, and by extension relaxation – this is great for people who have overtense muscles who experience back cramping or spasms, but relaxation over too long a time is what can cause atrophy.

It is of my opinion that wearing your corset to the point of atrophy is not beneficial. I try to maintain moderation in my tightlacing, where I enjoy wearing corsets but I also enjoy my uncorseted time. I don’t want to feel dependent (physically or psychologically) on the corset.

Not everyone experiences atrophy, however. Some corseters have even experienced that wearing their corset at a slightly lighter reduction has helped them improve their posture at all times (even when uncorseted) through muscle memory. Further, being lightly corseted has encouraged them to keep their abdominals engaged at all times. There are small things you can do to engage your muscles while wearing your corset. While I don’t necessarily condone trying to force your muscles to flex in a corset (typically you should not have to “fight” nor “help” a well-constructed corset), I occasionally push my abdominal muscles against the front wall of the corset as an isotonic exercise, and then I try to pull my abdominals inward, away from the front wall of the corset as much as possible, with a focus on the latter exercise. Even when you’re wearing your corset, it’s still possible to engage some of those muscles, at least up to a certain reduction – so atrophy of your core muscles while wearing a corset is not absolutely true.

Corsets, through encouraging a consistently proper posture, may help the vertebral ligaments to adapt and support the spine to maintain erect posture at all times

In a recent SciShow talk show, Michael Aranda and Hank Green discussed spinal posture and how slouching is encouraged by the ligaments between the vertebrae stretching over time. It was also proposed that this process is eventually reversible, and by maintaining a consistently erect posture, then the ligaments may shorten again (and the muscles of the back may become accustomed to holding this position) so that one’s “neutral” posture is naturally erect and can be enjoyed effortlessly.

 However, until the day arrives that your ligaments do shorten, many people find it exhausting to hold an erect posture, or they may often forget and begin to slouch again. Wearing a corset can serve as a reminder to maintain proper posture at all times that its worn. While overbust corsets or corsets with shoulder straps help to also keep your shoulders back, even wearing a normal underbust can help correct posture in the lumbar and low-thoracic area, and may help to set up the proper “stacking” of the rest of your vertebrae. By keeping your spine in this position, the ligaments may eventually shorten, whether or not your core muscles are engaged. Of course, if you do want to consistently use more of your own core muscles, you can simply wear your corset at a relatively light reduction, using it just as a rigid reminder to maintain proper posture but you’re depend more on yourself.


Does muscle tone impede your waist training progress?

Many people avoid exercising their core muscles because they believe that muscle is less compressible than fat (technically true), that well-toned muscles become larger over time (not necessarily), and therefore it will be more difficult to achieve their corseting goals (not necessarily). But in my opinion, this idea is not so simple.

The functional part of your muscles are called sarcomeres, which are contained inside the myofibrils, inside the muscle cells (myocytes). These are the fibers which are responsible for contraction. Surrounding your sarcomeres is the sarcoplasm, which is rich with glycogen, nutrients, and proteins like myoglobin that brings oxygen to the muscle cells.

There are two elements to muscle growth (hypertrophy): sarcomere hypertrophy, which increases muscle density, tone and strength but not so much size. This is why some people are little but mighty. Then there’s sarcoplasmic hypertrophy which makes the muscle bigger and puffier by increasing glycogen stores around the fibers, but this doesn’t directly affect the strength of the muscle.

Exercising your core can increase the size of the muscles, but most women don’t have to worry about this (there’s a genetic predisposition). But if you’re concerned about this, it’s worth researching ways to increase muscle tone without changing their size too much. I didn’t study exercise science in-depth but there are hundreds of forums that go into more detail about this – I personally just stick with the exercises I mention in the next section.

Exercises I do (out of the corset) to increase tone and prevent atrophy

I would always recommend regular exercise and toning (whether you wear corsets or not), but f you do plan to wear your corset more than half the time you’re awake (8 hours a day, 5-6 days a week or more), I would make daily core training a strict part of your regimen (unless you only wear your corset to sleep, in which case you’re not using your core to maintain upright anyway). It doesn’t have to be a lot of exercise, and it doesn’t have to be complicated. I gained considerable core strength by following Pilates instructional videos, as almost every move teaches you to keep your core tight, your ribcage in, and your muscles engaged at all times.

On my lazy days, even if I don’t do cardio, I will still do some some regular core-toning exercises, including 3 sets of: 50 bicycle crunches, 30 reverse crunches or leg lifts, and 20 seconds of planking (planks also strengthen the lumbar area of your spine). If you want to really work out your oblique section, side kicks in kickboxing will definitely strengthen this area. These exercises take less than 10 minutes altogether. If you’re not wearing your corset that day, you can break up your sets throughout the day: sitting through a commercial break, or waiting for your microwave to go off. I also keep my core engaged while on the elliptical or walking.


Can you “sculpt” muscle using corsets?

Whether or not you can change the shape of your obliques to give you more of an hourglass shape is disputed. If it does work, here is my hypothesis as to how: When you intensely work out your muscles, your fibers break down and must be rebuilt – typically denser and stronger, as your muscles are trying to prevent such mild injury from occurring again in the future. Directly after exercise (when your muscles are still warm, broken and tangled) is when many people recommend you stretch your muscles to help realign the fibers and encourage them to heal in a certain way. Corseting, especially with certain silhouettes, can definitely stretch the oblique muscles.

I try to plan out my day such that I can do some intense activity in the afternoon/evening, take a shower, and throw on my corset within an hour of finishing my workout, when my muscles are still warm and complacent. I’ve also suggested this schedule to others, and those who have followed this same regimen had reported back that it’s easier to get a stronger cinch in their corset this way (compared to corseting over a fully healed and/or cold muscle). IF oblique muscles are indeed encouraged into rebuilding themselves in an an hourglass shape with the use of corsets, this would be the best way that I can think of doing it.

Fran Blanche, owner and corsetiere of Contour Corsets, tested the long-term, semi-permanent effects of waist training on herself for a year. She fashioned a sports corset that was specifically designed to take the stress of exercising in a corset. She also mentioned that she’s naturally lean (low body fat percentage) and she wore her corset at a 35% reduction (that would be the equivalent of someone going from a 30″ natural waist to about 19″ corseted) and this is what she reported:

“My persistence of shape when out of the corset was high and I could palpate my muscles, so I know that the muscle wall had adopted the corset shape when out of the corset, about 4-5” larger than the closed corset interior waist size.  But as I said, I do not know of anyone else who did high reduction tightlacing with hard cardio in a specially designed sport corset, so my results may have been unique. “

It’s worth stating that I don’t necessarily condone working out in a corset because it can ruin a corset if it’s not made for this type of stress – I do know of some weight lifters who have used corsets in lieu of a lifting belt to support their abdomens, but unless you’re already experienced in both corseting and the exercises that you do, you know how to pace yourself and preferably monitor your cardiac output and respiration, AND you have a corset specifically made for exercising in, I would err on the side of not working out in your corset and simply putting your corset on as soon as possible after working out (and having a shower).


A little more on stretching:

Imagine the line that your oblique muscles form naturally – in general, it’s in a relatively straight line. When you are bending to one side, one oblique becomes stretched as the distance between your ribcage and your iliac crest increases. When you’re corseted, you are pulling the obliques inward, following the fact that a curve is longer than a straight line from point A to point B, this means that your obliques are stretched when wearing a corset at a relatively large reduction – and the corset mimics stretching of the oblique muscles simultaneously on both sides. When you first start corseting, you may experience this as a bit of soreness or warm/tingling feeling that’s reminiscent of stretching, say, your hamstrings.

This is another reason to go slowly with your corseting; your muscles and tendons need time to increase elasticity, in order to prevent injury. When I am tightlacing a little more intensely, I notice that my flexibility in the sides of my torso increases and I’m able to stretch further in my side bends when uncorseted.

In “The Contortionist’s Handbook” online, there is a short blurb on the effects of combining contortion with tightlacing, which is supposedly practiced by individuals in Germany, The Netherlands and Russia. The author writes

“the contortion training makes it easier for them to tight-lace rather extremely as well as the tight-lacing helps them to get more limber faster and most have been able to fold their backs a little bit over a year after beginning! One of the reasons can be that the corset simulates the effect to the body of a deep backbend or a backfold where the organs are very much compressed and displaced and the ability to breathe deeply is reduced. The corset wearer’s bodies has adapted to this due to the constriction and therefore the positions involving backbends are much easier to do than normally.”

Unfortunately I haven’t really seen evidence or correlation between tightlacing and backbends, although I do know that there are a few contortion artists that also happen to wear corsets (including Zlata, who can be seen wearing 16″ corsets here – NSFW). So as I say time and time again, take this information with a grain of salt, because correlation is not necessarily causation.

As you can see, wearing corsets does not necessarily cause atrophy or cause bad posture by creating a dependence on the corset – on the contrary, wearing corsets in moderation can actually help improve posture and can encourage your core muscles to remain engaged. Also, exercising and toning your core muscles is not necessarily unconducive to tightlacing; rather combining regular toning and corseting can help your body take on the shape of the corset semi-permanently if that is your wish. As I mentioned before, it highly depends on the individual and not only their body, but their habits: what type of corset, how long you wear it, how tight you wear it, what level of fitness you’re coming from, etc. I encourage beginners to slowly settle themselves into a moderate, balanced regimen and to approach tightlacing with a healthy perspective and realistic goals. Remember that any lasting changes will come about with time, and it’s not for the impatient.

  1. Hi, Lucy,
    I appreciate the time, research, and passion you put into your articles. This was beyond informative.
    I’m new to corseting. Since I’ve started training, my left side is curvier than my right. In fact, the left side of my corset no longer gaps, but the right side still does. Am I wearing my corsets incorrectly? Where exactly should the steel bones hit? Should I tighten the laces so that my right side is compressed more than my left? (Is that even possible?)
    Thanks in advance for your help,

    1. Hi Natalya, my apologies for the late response, for some reason this comment was flagged as spam before.
      I would measure each side of your corset and determine whether your corset is asymmetric – I have a tutorial on how to take measurements here.
      If your corset comes up symmetric, I would measure your body on each side as well using this tutorial to quantify how different your two sides are.
      Everyone is a little asymmetric to start with, but you should definitely not be becoming more asymmetric over time. The position of the steel bones largely doesn’t matter because they do not create the shape of the corset; this is in the fabric itself. The bones are just there to provide scaffolding and vertical tension so that the corset doesn’t collapse.
      Can I ask whether you are strongly right-handed? If you have significantly more muscle tone on the right side of your body, this side may be more resistant to the influence of the corset, whereas the weaker left side with less muscle tone may be more compliant.

  2. Girdle and corset dependency is a combination of both psychological as well as physological. But to be quite honest being daily in a vintage girdle or a corset that is properly fitted and you went through Corset or Girdle Training there are some serious health benefits. We as humans stand erect, standing erect along with time and gravity has a very negative effect on our internal organs. Choosing to be girdled or corset will without question counteract this negative effect by hold and supporting your interal organs. After a few weeks of training you will discover the benefits and you find not just your posture is much improved, your clothes fit so much beter, but you feel great with much more energy. You do get to the point once you can relax your stomach muscles and just rely totally on a girdle or corset to support your posture you find you really love being girdled or corseted everyday.

    There is difference between a corset and a girdle. A corset is great to mold and shape your figure in a healthy way. A corset will pull and hold your stomach in and give needed control and support. Where a vintage girdle (boned and zippered girdle) will give you needed control and support and should be worn when you are out of a corset.

  3. Hi Lucy,

    I am a dancer that requires core exercising. I’ve been dancing for 8 months and I always seem to have a hard time finding the time to wear my corset as I’m always dancing. Would wearing my corset only on the weekends still help me get closer to getting a semi-permanent smaller waist?

    In regards to back flexibility, I haven’t seen much of a difference of flexibility in my back prior to corseting and after corseting for a few months.

    1. Hi Ruby, getting any corseting time in would be more effective than nothing at all, but the body responds best to consistency – it’s often said that wearing a corset at 26 inches for 12 hours a day will get you better results than wearing a corset at 24 inches for only 2 hours a day (just as an example). I would personally wear the corset just after you finish your last dance / workout of the day, try to get in a little bit daily even if it’s just for a few hours. Some people sleep in their corset if they don’t have the time to train in the day, but that’s up to you and whether you’re personally able to fall / stay asleep while corseted.

  4. Hello Lucy!
    Here in Brazil lacers use to say a 300 abs *at least* and other 150 Back exercises are a must do when practing tigh lacing. They also say plank is an extra and does not count in this routine, 300 abs are only about regular crunches.
    Do you have any knowlege about this numbers or informations? Is it correct in your opponion?

    1. Hello Camile, if you are just beginning a routine, just do as many you comfortably can – if you cannot do 300 crunches at first, it’s fine, you can build up to it over time. Don’t push yourself too much, because if you injure yourself, it can set back your progress.
      Some people have neck problems and can’t do crunches at all. For those people, they may need different exercises. Pilates is wonderful because almost every exercise you’re taught to engage the abdominal muscles and “close” your ribcage, and hold the contraction which is even more effective than crunches.

  5. Excellent research, Lucy! I appreciate learning from you, so very much.

  6. Hi I am 50 and want to wear a corset jus to flatten my abs. I have recently started gyming and want to maintain a flat tummy. Question though. Does wearing a corset assist a person in eating less?

    1. Hello Lizzy, I personally find that a corset helps me eat less, but you also must choose the right foods! I have an article all about the Corset Diet here.

  7. Hi Lucy. I’ve been following your YouTube channel for a while not and the one on muscles was helpful to me back when it came out, since I have a lot of muscle tone in my abdomen and back, and not much fat. I found myself coming back to it because while ive found using a corset after exercise to be helpful, it’s not entirely practical for my exercise schedule and I wondered if using one after massage could have a similar effect?
    I don’t wear my corset more than a few hours a day, because my work involves lots of bending and heavy lifting and just generally doing things which I find difficult to do with a corset on. Because of the nature of work I do, I get very stiff shoulders, neck, back and thigh/hip muscles, and so I get sports massages or KCR every now and again to work out the knots and the tension, which has made a massive difference. Since I usually come away with warm, slightly sore muscles the next day, similar to the feeling of having done too much exercise, I wondered if a corset after massage would be useful too, especially since most of my exercise occurs on the way to and from work and carrying a corset to put on when I get there is a bit awkward.
    I guess the only way to know is to try next time I go in for a massage.

    1. Hi Tina, I’m not sure how massages would affect corset training, but my guess is that wearing your corset after a massage is not necessarily going to prolong or halt your training progress. A great person to talk to about this would be Sarah Chrisman actually, because she is a registered massage therapist, and the only known therapist that has developed a massage specifically to aid tightlacers and lifestyle corset wearers!

  8. Is it possible/a good idea to combine a corset and cardio & weight training?
    I want to have a smaller waist, but not extremly small and I want abs too.

    1. Hello Z, the best way to develop your ab muscles is by core strength training (like the exercises I show in the corresponding video). However having a relatively low body fat % will help your abs show through, and cardio *may* help with this. However, I do not recommend working out in a corset, as explained in this article.

  9. You outdid even yourself, Lucy. (Is it possible to outdo oneself?) A thousand thanks for the effort, research, and thought you put into this video. I don’t wear corsets every day, but I had been wondering about the effects on my obliques and posture in general. This put my concerns to rest. Even with my lackadaisical corset wearing I’ve noticed a beneficial effect on my posture. This post inspired me to search for a donate button. It seems you don’t have one. :(

    1. Thank you so much for your kind words, Janina. :) I’m so happy to know that at least one person appreciates the work I put into these blogs. I did have a donation button for awhile, but nobody had used it for a long while so I just took it down. I appreciate the fact that you had wanted to support me, in any case – thank you for the sentiment. ^_^
