Your breastbone and the ribs beside it push outward, so the middle of your chest reads as a bump or a keel. It is the most brace-responsive of the three, and a flexible chest usually flattens without surgery.
Joined by 1,000+ people fixing their chest without surgery, since 2015
The costal cartilage joining the ribs to the breastbone grew longer than the frame it sits in, so the sternum was pushed forward. Same tissue as a sunken chest, pushed the other way.
Carinatum usually appears or worsens in the early-to-mid teens, and it can arrive fast enough to feel like it happened over a summer. That is also the window when the chest gives most easily.
A flexible carinatum chest is the single most correctable non-surgical case on this site. Steady compression is a well-established treatment for it - the constraint is almost never the chest, it is the hours.
It isn't caused by lifting weights, by pushing your chest out, or by anything about your posture - though posture can make it read worse than it is. And it isn't a case where you have to choose between bracing and training: in the trial below, every group did daily exercises alongside the brace, including the one that improved most.
A brace applies steady pressure across the bump. Cartilage under sustained load remodels toward the shape it is held in, so the bump flattens over months rather than snapping back. Clinicians measure a chest's flexibility first - the pressure needed to push the bump flat - and brace the flexible ones instead of operating. The variable you control is wear time, and it is the one that decides the result.
A cohort in which each chest was flexibility-screened first. The conclusion: bracing is a valuable option for correcting carinatum in a patient with a flexible thorax.
In a randomised controlled trial of 23 h/day, 8 h/day and control, every group improved and the 23-hour group improved most, with no extra side effects.
Every arm of that trial did daily exercises alongside the brace. The two are not alternatives - the brace moves the bump, the training holds the frame around it.
These are in order, cheapest first. Each one adds something the one below it doesn't give you. Most people start at 01 and stop wherever their chest stops needing more.

My son is 15 and had started keeping a shirt on in the pool, which is how I worked out something was wrong in the first place, because he certainly wasn't going to tell me. He would never have stuck with the brace on his own. It was the fortnightly check-ins that did it - he didn't want to turn up with nothing to report. Six months now and the bump has visibly come down. He swims without the shirt.

I came across your blog about a year ago and I just want to say how much you've changed my life for the better. I thought it was going to be another average article, but the tips you gave were things I hadn't heard of before. Now I've improved so much and im more confident then ever.

Two months in and I've put on 3 kg of muscle. My chest doesn't cave the way it used to when I'm standing relaxed, and that alone was worth it.

Had the flare since i was about 14 and just assumed that was my ribcage, permanently. Brace plus the breathing drills and my mrs asked when i'd lost weight. I hadn't lost anything, it's just the ribs sitting where they should now.

didnt know you could be breathing wrong for 21 years. thats the whole thing right there. flare started going down on its own once i stopped breathing into my shoulders, which is not what i paid for but ill take it

the bell leaves a red ring on your chest the second you take it off, and nobody warns you about that. it fades within the hour and the skin has never been an issue since. 100% satisfied - the sternum sits higher than it has my whole life

He knows more about this than the two consultants I paid to see, which says more about them than it does about him. Showed my GP the 9 month photos and he asked me for the website. Half a star off because the time zones make the calls a nightmare from Ireland.

ive bought like four programs for this over the years and quit every one of them by week two. finished this one. i think its cus you cant move on until you can actually hold the position, so theres never that thing where you're guessing if youre ready or not

I went in wanting to debunk it, honestly. Started opening the citations one at a time and they were real papers that said what he said they said. That is a depressingly low bar and nowhere else online clears it.

bump is 0.5cm down in 5 months. bro i genuinely thought this was gonna be bench press for a year, its like 80% breathing drills and posture stuff. wasnt what i signed up for but i cant argue with the tape measure

every doctor said come back when youre done growing, which is a mad thing to say to a 17 year old whos already miserable about it. did four months of training instead. 4kg on and my t shirts actually sit on something now

1 cm off the depth in eight months. I had this filed under things about my body that got decided before I was born, and I'd stopped thinking about it somewhere in my twenties, so being wrong about it has been a strange few months honestly.

i did abs for two years thinking that was the fix. it was never going to be abs. three months of the brace plus actually learning how to exhale properly and its 1.5cm narrower down there

“I'm 52. I have both a bump and a dip, which I'm told is unusual, and I've had the pair of them since I was a boy. Nine kilos off in five months and for the first time my chest looks like one chest. I did not expect to be sorting this out at my age, but there we are.”

Take the 60-second quizPosture and breathing shift inside the first few weeks. Visible chest change is slower - in the case log above, Milo hit his at 2 months, Ian at 6. The programs run 16 weeks because that is how long it takes to show in the mirror.
Almost certainly not. The clients on this page were 22 to 32 when they started. Cartilage stiffens with age, so progress is slower, but slower is not stopped. Age changes the timeline, not whether it is worth doing.
Either works. Every program ships with a gym track and a no-equipment track for the same 16 weeks, and you can switch between them mid-program without losing your place.
No, and that matters. A sunken chest and a protruding chest need close to opposite work, and rib flare rides along with both. There is a separate program for each, if you are not sure which you have, the 60-second quiz sorts it out.
The trial group that improved most wore it 23 hours a day. The 8-hour group still improved, just less. Treat that as the trade: hours buy speed and final result. In practice most people settle at "everything except showering and sport" for the first phase, then taper to nights.
A flexible chest usually shows measurable change in three to six months, with most of the correction inside the first year. Then comes a maintenance phase of nights-only wear so it holds. Stopping the moment it looks flat is the most common way people lose the result.
Cartilage hardens with age, so an adult chest needs more pressure and more months, and may only correct partly. The screening question is not your age, it is how much your bump gives when you press it. If it moves, bracing is worth a run.
Under a t-shirt, mostly no - it's a strap and two pads, not a cast. Under something tight, the front pad can show. Most people wear it fine at school or work, and the fitting matters more than the clothing does.
It should compress, not crush. Marks that fade within an hour are fine. Persistent purple skin, blisters, broken skin or actual pain mean the pressure or the hours are too high - back off. Measured pressure beats maximal pressure every time, because it is the only kind you will keep wearing.
Yes, and you should - every group in the randomised trial did daily exercises. Take the brace off for the session, train, put it back on. The exercise side is not an alternative to the brace and it doesn't interfere with it.
