An instrument, not a promise. Log your wear time and training, scan your chest, and watch one number - your Correction Index - actually move. On a plan that recalculates every week.

No mockups on this page. Every screen below is the real thing, running.
Device dosing, training, food, scanning, and the reasoning behind all of it - kept in one place so nothing lives in a notes app anymore.
Your day at a glance: Correction Index, what to do next, and the minutes it takes.
The session for today, plus vacuum-bell and brace timers running against a daily wear target.
Calorie and macro targets that move with your weekly weigh-in, and a food log to hit them.
Capture a 3D scan of your chest, read the depth heatmap, and compare it against earlier ones.
Correction Index, chest depth, wear hours and training volume, laid out over months.
Cited explainers and a searchable technique library - the why behind every step.
A weekly review that reads what you logged and adjusts your dose accordingly.
Working with me 1-on-1? This is where I read your scans, adherence and index, and leave notes.
The Correction Index folds your chest depth, rib angle, wear hours and training into a single 0-100 read. Underneath it sits the only other thing you need in the morning: the next thing to do, and how long it takes.
Every exercise carries a plain-language reason and a demo video, so you are not copying a shape you do not understand. Device timers sit on the same screen: start the vacuum bell, log the minutes, watch the daily target fill.
Capture a standardized scan every couple of weeks. The depth heatmap is driven by your own measurements, and every scan stays side by side with your baseline so the change is visible rather than remembered.
Chests do not move week to week, which is exactly why people quit. Progress plots the long view: index, chest depth against your target, wear hours, training volume, and how it has actually been feeling.
Muscle in the chest, shoulders and upper back is the biggest visual lever you have. Targets are set for a small consistent surplus, adapt from your weekly weigh-in, and cite the study they came from.
The protocol is explained where you are running it, not in a course you watched once. Search the technique library, open the condition hub, and follow any claim back to the paper it came from.
It doesn't guess. It reads what you actually did, then changes the plan to match. Log, scan, recalculate - on repeat.
Log your wear time, training, and how you felt. About a minute a day.
Capture a 3D scan when you are ready. It reads chest depth and rib angle.
Every week it re-reads your logs and scan, then adjusts the dose to match.
then it starts again on Monday, with your new numbers
Nothing is locked behind a waiting period. You finish onboarding and the whole thing is built: diagnosis, program, dose, and a baseline to measure against.
Your case, your measurements, your training history and what bothers you. About three minutes.
Your diagnosis, correction potential, an honest timeframe, and the program built for it.
Breathing work, your device timer, and the day's exercises with a reason attached to each.
The scan every future one is measured against. Your first Correction Index lands here.
all of it inside the free trial, before you are charged anything
Most correction apps sell you a result. This one sells you a better way to work at it. The difference matters, so here it is in plain terms.
You can track this in a spreadsheet or a habit app. Neither one knows what your chest is doing, or what to change when it stalls.
It opens in the browser on any modern phone, tablet or computer - iPhone, Android, Mac, Windows. There is no app store, no download, and no update to chase.
Scans use the camera on the device you are holding. Your logs and scans stay on that device, and the whole member area is kept out of search engines.
"I built the tool I wish I'd had - the one that told me the number, not a pep talk."
Mihail Veleski · Founder, mrpectus
I have pectus excavatum. I spent years correcting it without surgery - vacuum bell, breathing mechanics, structured training - and I logged all of it because I needed to know whether any of it was working.
The app is that logbook, cleaned up and made to think for itself. Every protocol in it is the one I teach, carrying the same studies I read to build it - not advice invented for a subscription.
It won't do the work for you. It'll just make sure the work you do is the right work, and show you the number moving.

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.

Had rib flare since i was a teen. the brace plus the breathing drills changed everything. my waist looks normal in a fitted shirt for the first time in my adult life
Daniel K. Rib Flare 27
Rib Flare Brace Bristol, UK 🇬🇧
Mihail doesnt sugarcoat anything. told me exactly what to expect and exactly how long it would take. 12 months in and my carinatum is flat. i finally take my shirt off at the beach
Aiden R. PC 19
1-on-1 Coaching Melbourne, Australia 🇦🇺
spent two years researching surgery before i found this. six months in and i wish id found it sooner. the progress photos dont lie
Tom W. PE 24
Pectus Excavatum Course Manchester, UK 🇬🇧
the breathing protocol alone changed how i feel day to day. didnt realise how shallow i was breathing until i fixed it. the rib flare correction kind of followed on its own
Sam B. Rib Flare 21
Rib Flare Course Oregon, USA 🇺🇸
Was skeptical, id tried everything before. the custom vacuum bell was different to anything id used. three months of consistent use and i can already see the sternum coming up
Chris L. PE 31
Vacuum Bell Toronto, Canada 🇨🇦
The carinatum brace is really well made. fits perfect to my chest and i can wear it under a t-shirt at work. results started showing around 4 months
Nico P. PC 17
Pectus Carinatum Brace Milan, Italy 🇮🇹
direct, no nonsense. mihail knows this condition better than any doctor ive seen. my GP was shocked when i showed him my 9 month comparison photos
Ryan H. PE 29
1-on-1 Coaching Dublin, Ireland 🇮🇪
the course structure is exactly what i needed. not overwhelming, not vague. each module builds on the last and you always know what to do next
Jake M. Rib Flare 23
Rib Flare Course Texas, USA 🇺🇸
been watching mihails youtube since 2017. finally bought the program in 2023 and kicked myself for waiting. shouldve trusted him years earlier
Liam O. PE 26
PE Exercise Program Auckland, New Zealand 🇳🇿
My son is 15 and was getting self-conscious at the pool. The carinatum brace and the fortnightly check-ins are what kept him consistent. Six months and the ridge has visibly dropped.
Parent of Ethan PC 15
Pectus Carinatum Brace Michigan, USA 🇺🇸
what sold me is that every claim links to a study. only place online that treats pectus like an actual training problem instead of selling a miracle
David P. Rib Flare 34

Seven months with the bell now. dip is maybe half what it was and i've stopped turning sideways away from people at the gym lol. didnt expect that part
Tobias PE 24
Vacuum Bell Hamburg, Germany 🇩🇪
started at 19 with a chest i couldnt look at in the mirror. went with the excavatum course cus everyone kept telling me nothing but surgery works and i didnt buy it. 5 months of doing the work most days and my chest sits noticeably flatter now - the surgeon who told me wait and see at 17 wouldnt recognise it. only regret is i didnt start the day i turned 17
Wes PE 19
Pectus Excavatum Course Colorado, USA 🇺🇸
Nine months in and my cardiologist literally asked what id changed. resting heart rate came down and i sleep breathing through my nose now. still kind of wild to me
Andrés Vásquez PE 31
1-on-1 Coaching Santiago, Chile 🇨🇱
1100 pages sounded ridiculous til i realised its a reference not a book you read front to back. im in the vacuum bell chapters basically every day
callum_g PE 22
Breathe Deeper Glasgow, Scotland 🏴
Back and rear delt work changed how my chest reads more than anything i did to the actual chest. did NOT expect to be told that
Dmitri PE 29
PE Exercise Program Riga, Latvia 🇱🇻
App keeps me honest ngl. i log the bell session and it tells me when ive earned the next step up. before this i was just guessing
Joon-ho Park PE 26
The app Seoul, South Korea 🇰🇷
my mum found mihail tbh. four months of coaching and the difference between the photos is obvious. never had to sit in front of a surgeon
Tomás Ferreira PE 17
1-on-1 Coaching Porto, Portugal 🇵🇹
gaining weight was the bit nobody would explain to me. 3 months on the nutrition plan, 5kg up, and the same chest reads completely different at that weight
Felix PE 28
Pectus Nutrition Program Graz, Austria 🇦🇹
It works. the suction takes getting used to and i gave myself a bit of skin bruising the first fortnight, until i dropped the pressure back to what the guide actually says. my fault not theirs
Marc-Antoine PE 33
Vacuum Bell Quebec, Canada 🇨🇦
honest review. 5 months of consistent bell use and my depth has barely moved. im 35 and my chest wall is stiff, which the guide does warn about upfront. the posture and breathing side genuinely helped and i dont regret the money, but i wouldnt tell someone my age to expect what the teenagers are getting
Nikolai PE 35
Vacuum Bell Guide Sofia, Bulgaria 🇧🇬
dip and flare at the same time. THE FLARE WENT FIRST, which nobody warned me would happen, and that alone changed my whole silhouette
Bruno Salgado PE + Rib Flare 30
1-on-1 Coaching São Paulo, Brazil 🇧🇷
brace did its job on the flare. what i actually wanted was how to run it alongside the vacuum bell work in the same week. asked and got a proper answer same day, but that should be in the material, not something you have to know to ask for
Otto PE + Rib Flare 25
Rib Flare Brace Tampere, Finland 🇫🇮
Everyone i asked just told me to do more core. turns out i was breathing into my neck this whole time. learning to actually use my diaphragm was the entire fix
Georgia Rib Flare 24
Rib Flare Course Perth, Australia 🇦🇺
started out flat on my back every night checking whether my ribs still stuck up, they always did. got the rib flare program and actually did the breathing side properly this time instead of just the exercises. four months later i lie down and theyre flat - i still check out of habit and still cant quite believe it
Hanna Rib Flare 22
Rib Flare Program Malmö, Sweden 🇸🇪
the fortnightly check-ins are the only reason im still doing this. left on my own id have quit around week 3, easy
Katarina Rib Flare 31
1-on-1 Coaching Split, Croatia 🇭🇷
obsessed with watching that number drop every month ngl. 10/10
marta_v Rib Flare 25
The app Valencia, Spain 🇪🇸
clear, cited, actually practical. heavy going in the anatomy chapters if you have no background, but id rather be given too much than too little
Aisha M. Rib Flare 27
Rib Flare Brace Guide Dubai, UAE 🇦🇪
material's good and i have no issue with the science. my honest gripe is the early modules cover the same ground as the free blog posts, which id already read before buying. the later phases are where the real value sits. wouldve paid the same to skip straight to those
Stefan Nagy Rib Flare 34
Rib Flare Course Budapest, Hungary 🇭🇺
Wore it 8 hrs a night for 5 months. the ridge is basically gone. im 16 so i got lucky on timing, but you still have to wear it every single night. beat the operation they were lining us up for
Elias PC 16
Pectus Carinatum Brace Bergen, Norway 🇳🇴
The wear-schedule chapter is honestly the whole product. everywhere else online just goes "wear a brace" and leaves you to figure out the rest
hamza PC 20
Pectus Carinatum Course Casablanca, Morocco 🇲🇦
spent two years hiding the ridge under hoodies before i actually did anything about it. what changed it was the carinatum program - building the chest and back around the ridge instead of just bracing and hoping. six months in and it reads flat enough that the hoodies are gone
Rafael PC 22
PC Exercise Program Cebu, Philippines 🇵🇭
He replied to my messages same day, every time. at 17 with a chest you hate, that matters way more than the plan does honestly
Théo PC 17
1-on-1 Coaching Ghent, Belgium 🇧🇪
solid guide and the pressure numbers are genuinely useful. half a star off cus im 28 and the whole thing is pitched at teenagers. an adult section, where the timelines are honestly different, wouldve been worth a lot to me
Jonas B. PC 28
Carinatum Brace Guide Aarhus, Denmark 🇩🇰
Two months in and I've put on 3.2 kg of muscle. My chest doesn't cave the way it used to when I'm standing relaxed, and that alone was worth it.
Milo PE 25
Germany 🇩🇪
Nine months, 5.7 kg of muscle on, and 0.9 cm off the depth of my chest. I am 32. I had been told the window for fixing this closed at 18.
Liam PE + Rib Flare 32
Seattle, WA 🇺🇸
I came in skinny with a deep dip and ribs that flared out. Six months later I am 4.5 kg heavier, and the flare is the part people notice is gone.
Ian PE + Rib Flare 22
Canada 🇨🇦
The brace handled the flare, the training filled out the chest. 6 kg on and 0.9 cm less depth in seven months. I wear fitted shirts now.
Alejandro Sanz Torres PE + Rib Flare 29
Bilbao, Spain 🇪🇸
Five months, 4 kg up. The dip is still there if I go looking for it, but nobody else finds it anymore.
Lars PE + Rib Flare 25
Sweden 🇸🇪
I am 52 and carried both a ridge and a dip my whole life. Dropped 9 kg in five months and my chest finally reads as one shape instead of two.
Greg Henderson PC + PE 52
Ohio, USA 🇺🇸
Three months, 5 kg on, and the ridge sits lower than it ever has. At 19 I thought surgery was the only thing that would fix it.
Ethan PC 19
North Carolina, USA 🇺🇸
Nine kilos in six months. Building the muscle around the ridge did more for how it looks than the years I spent hiding it under loose shirts.
Omar Al Mansoori PC 24
Abu Dhabi, UAE 🇦🇪
Four months of coaching and the ridge you could see from the side has flattened out. I stopped checking my profile in every window I walk past.
Beau PC 30
Missouri, USA 🇺🇸
My carinatum was the first thing I saw in every photo of myself. Now I have to point it out to people. Same chest, trained differently.

“Nine months, 5.7 kg of muscle on, and 0.9 cm off the depth of my chest. I am 32. I had been told the window for fixing this closed at 18.”
“I came in skinny with a deep dip and ribs that flared out. Six months later I am 4.5 kg heavier, and the flare is the part people notice is gone.”
“The brace handled the flare, the training filled out the chest. 6 kg on and 0.9 cm less depth in seven months. I wear fitted shirts now.”
“Five months, 4 kg up. The dip is still there if I go looking for it, but nobody else finds it anymore.”
“I am 52 and carried both a ridge and a dip my whole life. Dropped 9 kg in five months and my chest finally reads as one shape instead of two.”

“Nine kilos in six months. Building the muscle around the ridge did more for how it looks than the years I spent hiding it under loose shirts.”
“Four months of coaching and the ridge you could see from the side has flattened out. I stopped checking my profile in every window I walk past.”
“My carinatum was the first thing I saw in every photo of myself. Now I have to point it out to people. Same chest, trained differently.”
The four that come up most, answered the same way I would answer them on a call.
Take the 60-second quizPosture and breathing shift first - most people feel that inside the first few weeks. Visible chest change is slower. In the case log above, Milo saw his first real change at 2 months, Ian at 6, Liam at 9. The programs run 16 weeks because that is roughly how long it takes for the training to show up in the mirror.
Almost certainly not. The clients documented on this page were 22 to 32 when they started. Cartilage does stiffen with age, so progress is slower the older you are - but slower is not the same as stopped. What changes is 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, so you pick the one that matches what you actually have access to. 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 often rides along with both. There is a separate program for each. If you are not sure which one you have, the 60-second quiz sorts it out and points you at the right starting place.
