“You know that’s not actually doing anything, right?”
That’s what my trainer said, mid squat rack, while I was adjusting my underbust corset between sets like it was a normal accessory for a Tuesday morning workout. It is not a normal accessory for a Tuesday morning workout. I know that now. I sort of knew it then too, but I’d paid ninety four dollars for the thing and I was determined to get my per wear cost down, gym included, because that’s genuinely how my brain is wired at this point, my mother says I’ll do math at my own funeral.
He wasn’t rude about it. He just stopped, looked at me the way you look at someone about to eat gas station sushi, and asked why I was wearing it to train in.
I said waist training, obviously, the way you say something you read once and never fact checked. He asked if I could take a full breath. I could not, in fact, take a full breath. That was sort of the point, I thought. Turns out that was also sort of the problem.
What I actually learned about corsets from someone whose job is bodies, not fashion
He wasn’t lecturing me for wearing one in general, to be clear, this wasn’t a moral position, more a mechanical one. His issue was specific: a garment that compresses your midsection hard enough to change your silhouette is also, unsurprisingly, compressing the muscles that are supposed to be doing actual work during a workout. Your core stabilizes you during literally everything, squats, deadlifts, even just standing there holding a kettlebell like you know what you’re doing. If that core’s been cinched into submission by boning and steel busk, it’s not stabilizing anything, it’s just along for the ride, restricted, breathing at maybe sixty percent capacity, doing the exercise equivalent of showing up to work with one hand tied behind your back and calling it dedication.
He also mentioned, almost as an aside, that he’d trained someone years back who wore a waist trainer religiously during sessions and eventually complained about digestive issues, and while he was careful to say he’s not a doctor and wasn’t diagnosing my corset as the culprit of anything, the correlation stuck with him enough that he brings it up now when he sees one on a client. Take that with whatever grain of salt you want, it’s one guy’s anecdote, not a study, but it’s the kind of thing that rearranges your priorities fast when you hear it standing in a gym in workout leggings, sweating, definitely not breathing properly.

Here’s the thing though, and I want to be fair to the corset here because it’s not the villain of this story. Worn occasionally, for a few hours, over a dress, laced comfortably rather than to the point of genuine distress, it’s just a garment. People have worn structured shaping pieces for centuries without keeling over. The difference is context. Wearing one to a wedding for four hours where your main physical exertion is holding a champagne flute and nodding at your cousin’s new boyfriend is different from wearing one while your body is trying to squat its own body weight. I’d sort of collapsed those two situations into one in my head, treated the corset like a background accessory that just happened to also be present during exercise, when really it should have been treated as incompatible with exercise entirely, full stop, no crossover.
Is it actually good for you, or does that depend entirely on what you’re using it for
So is wearing a corset good for you. That’s the search that brings people here, I know, and I’m not going to pretend I have a medical answer, because I don’t, and neither does my trainer, that’s not his lane either. What I have is ninety four dollars spent, one very awkward gym conversation, and a slightly better sense of the actual question, which isn’t “is a corset good” in some universal sense, it’s “good for what, worn how, for how long.”
For occasion wear, a few hours, laced to something you’d describe as snug rather than crushing, I don’t think it’s the villain some people make it out to be. I’ve worn mine to two events since the gym incident, both times over a dress, both times taken off the second I got home with the kind of relief usually reserved for taking off tights.
Cost per wear on that thing is currently at eighteen dollars and eighty cents, which I recalculated twice because the first number felt too generous and I didn’t trust myself, and honestly it’s still not great, I need more events in my life or fewer corsets, and given my track record it’s probably going to be more corsets.
For anything involving actual movement, exercise, long stretches of sitting, a full workday, I’ve landed firmly on no. Not because I read a study, I didn’t, because I stood in a gym unable to take a full breath and a professional who watches bodies move for a living told me that was the compression doing exactly what it’s designed to do, just in entirely the wrong setting. That’s a personal experience, not a medical verdict, and I’d say the same to anyone asking, don’t take my word or his as gospel, but also maybe don’t need a study to tell you that restricting your own breathing during a deadlift is a bad plan.
The corset’s not banned from my closet. It’s just been reassigned. Occasion piece, not gym gear, not office wear, not anything requiring me to bend at the waist without wincing. That’s buy number six for the questionable column this year, redeemed only because I finally figured out what it’s actually for, which took an audience of one confused personal trainer and a squat rack to work out.
