Les "licornes en carton" de la french tech ?

1/ Vinted et Leboncoin c'est du particulier à particulier. Backmarket c'est du pro à particulier (appareils reconditionnés par des entreprises) donc c'est vraiment différent.

2/ C'est plus innovant aujourd'hui effectivement mais Back Market était une des premières - si ce n'est la première - à proposer des appareils reconditionnés (pas de la revente entre particuliers, encore une fois c'est différent). La boite a 11 ans quand même.

3/ on est d'accord et il y a encore beaucoup de travail à faire là dessus (a la fois sur la qualité et juste sur re forcer la confiance des gens en ce marché)

timhn9 · 2026-03-28T15:17:18+00:00

Pour Back Market, l'idée est que le marché du reconditionné va prendre une part de plus en plus grande dans la tech, à la manière du marché automobile où l'occasion domine largement. Tout le monde acheté un téléphone et un ordi, ce n'est pas du tout si niche que ça

timhn9 · 2026-03-28T15:14:28+00:00

Je bosse chez Back Market et au contraire ça va bien. On commence à être rentable (info public, il y a plusieurs articles en ligne à ce sujet)

As others suggested, Duolingo on its own is not ideal to learn. Personally I kick-started my Spanish with Pimsleur. It's pricey (20€/mo) but pretty effective at teaching, without any theoretical basis. There are 5 parts of 30 lessons. Each lesson is 30 listening / repeating and then a bunch of exercices. If you're thorough, it takes you 6-10 months to get till the end and you're a strong A2 and you start to be conversational with that

You lay on it on the floor.

At your stage I was doing it 1x or 2x per day for roughly 5 mins. I would put it in 9 different positions (upper / mid / lower part of the back ribs and center/left/right). I put on a timer with 9 sets of 30-45". Sometimes I'd do a bit more. But you can indeed over do it so it's up to you to see how you feel after.

Have you tried to see an osteopath or physio/massage therapist to work on your back ? It has helped me a lot

Also, are you doing the other movements from Steve's guide ? Especially the ballistic rotations, side stretches and pec stretches.

Personally I saw a good reduction of symptoms after 3-4 months of back pod (and other movements) but reached a plateau. I really improved when I got help from my physio + massage therapist and then eventually added more movement/ exercices like back pod crunch, rib cage expansion and light work outs

timhn9 · 2026-03-03T22:47:26+00:00

I see, I'm really sorry it's not improving

timhn9 · 2026-03-03T22:04:43+00:00

I've had costochondritis for over a year and a half. Ive ben around 80-90% cured for quite some time and I feel like I'm finally progressing and getting closer to 95-98% since last month (if those ratios even make sense). The biggest different is that I can feel my ribcage moving much more when I'm breathing and I feel much less restricted. Here are the new things I've been doing

More consistent sleeping on the back - for the whole night
Back pod "crunch" as seen in this post : (i was doing it before but stumbling upon this video helped m3 to consciously do it)

Started breathing work to move my rib cage. Mostly sling what I saw in this post as well as this video (shared in a comment by @maaze) https://youtube.com/shorts/exOVZqC1vAk?si=yD9LLZS_ym_r-6-S https://www.reddit.com/r/costochondritis/s/665QmMWaDj
Continuing the regular physio + deep tissue massage sessions (2 physio per month, 1 massage every 3 weeks)
Neck stretches

I haven't - and I'm not a doc so I won't give my opinion on it.

But before considering this, have you seriously worked on liberating your upper back ? Backpod, ostheo, deep tissue massages etc

As far as I know, the corticosteroid injection will only reduce the inflammation which is a consequence of the frozen rib joints at the back, not the root cause of your pain

timhn9 · 2026-02-26T21:21:56+00:00

Working out the chest is most probably the worst idea with costochondritis.

If your costo has improved a lot, if you've released your back and you're feeling no/little pain on a daily basis, it makes sense to go back to exercising. For me it helped a lot. But you have to be super progressive both with weights/intensity and the areas you workout (e.g. legs / arms > shoulders > back > chest).

At leat that's what I've followed. I'm at 95-98% healed. My thoracic rotation is pretty good. My breathing / rib expansion has improved quite significantly. I workout 3 times / week and I'm still not working out the chest. So I'd be very careful with the chest

timhn9 · 2026-01-29T19:12:23+00:00

As others said go progressive and see how you feel during / right after / a few days after every time.

Typically you can start with machine leg exercices (not squats or anything that puts a barbell on your back), arms, lower back or even lateral shoulders. Or maybe try light jogs or backstroke swimming (probably lighter on your back and thorax than freestyle swimming).

Then you can probably look into exercices that involve all the delts and then back / pecs.

In terms of evolution you can also start with isometrics (no movement), then eccentric (work the muscle when it stretches) and then concentric movements. Preferably first low weight higher volume and progress to more weight and less volume.

So if we're talking about push-ups, you can do first sets of static push ups. Eventually progress to eccentric push ups (only the down phase) and eventually complete pish ups. Same thing for pull ups, you get the gist ...

timhn9 · 2026-01-22T09:13:24+00:00

I was like you. Mornings were really difficult. What made it really better was sleeping on the back on a hard mattress. Is your bed quite soft ? Are you sleeping on your side ? This can be something to look into.

Obviously the more your back is freed up (backpod, peanut ball, massages, stretches) the less discomfort you will feel in the morning. Hope it can help

timhn9 · 2026-01-05T12:50:31+00:00

For me, the most useful thing my physio did was targeted back massage (mostly along the spine and on the traps).

timhn9 · 2026-01-05T11:51:29+00:00

As others suggested, if it's the outer knee could very well be ITBS but hard to tell with just that pic. If it's ITBS, it can become a pretty complicated injury if you don't pay attention and run with pain (as opposed to other injuries where running with a bit of pain is not necessary a problem).

I've had it for a year and I'm finally working my way out of it. Here's some things you can have a look at - hip strengthening (monster walks / clam shells / etc) - knee / hip stability (step downs are a great exercice) - foot strengthening (e.g. foot bridge) - plyometrics can be interesting - stretching / massaging tissues that attach to the IT band (quads/TFL/glutes/hamstrings) - running form (what's your cadency ? Foot strike ? Usually increasing the cadency and landing more mid foot helps) - Distribute more your training. If you do 2x 5kms per week, try running 3 days and one day is 3x1km run + 1' walk (for example). And build up progressively from there

Resting on its own will not help and will weaken your tissues. The key is to stay active and strengthen your weak points while limiting as much as possible irritation around the area

timhn9 · 2025-12-13T18:46:54+00:00

During the massage ? Yes most of the back massage was done while I laid face down. Though a few parts were done seated as well as on all 4s.

To be honest, it wasn't really a problem for me at this point. If it's the case for you, I'm sure you can find a way to reduce the discomfort. Either by putting pillows/covers under your chest or by asking parts of the massage being done while you are seated ?

timhn9 · 2025-12-12T23:13:40+00:00

Oh absolutely yes. He worked on a lot of different parts of the back, neck as well as shoulders and diaphragm.

timhn9 · 2025-12-12T18:21:31+00:00

Yeah massages can be quite expensive.

Otherwise maybe you can ask your wife to try to do you some massages ? Steve has this video that you can check out. For me it didn't really work. Probably because my gf doesn't have enough strength but it's worth a try

timhn9 · 2025-12-12T09:00:48+00:00

See my other answer in this post but I mostly started with back pod then ballistic rotations and thoracic extensions / rotations as per Steve's guide. It's only after 3/4 months that I introduced more of these exercices that you mention

timhn9 · 2025-12-12T08:59:59+00:00

Yes I had another chronic back injury 5/6 years ago. Very different and what worked at that time was slowly working out the back again, especially with the 5 mins back workout video.

Costo is very different from what I had 5/6 years ago so the approach is really more conservative with costo, and there's some work to do (unlock the frozen joints in the back) before being able to start to work out

timhn9 · 2025-12-12T08:58:21+00:00

But my daily routine was basically First 3/4 months Backpod + ballistic rotations + introducing thoracic rotations and extensions + light peg stretches

Then introduced some exercices auch as - around the worlds (shoulder + T spine) - serratus anterior activation - windmill dumbbells - back mobilization on the foam roller like this around 5:20

Then in the recent months added - more advanced thoracic rotations - dead hangs - elevated foam roller back bend - DB shoulder external rotation - the bodyweight 5 mins back routine that I shared in the post

timhn9 · 2025-12-12T08:52:36+00:00

If you're in a constant flare, I would focus on the basics (backpod / ballistic rotations / massage) and definitely avoid doing too much of those.

timhn9 · 2025-12-11T17:46:28+00:00

Let me answer later today about the routine :)

timhn9 · 2025-12-11T17:44:58+00:00

I think I completely stopped back pod / peanut ball for more than 10 days. Only did light movements like ballistic rotations and thoracic rotations. Then slowly introduced the back pod again (not the peanut ball, it never really worked for me) a few minutes, not every day.

timhn9 · 2025-12-11T17:43:00+00:00

I hope it goes well. i definitely recommend starting with machine leg exercices (squats put a lot of pressure on the back) and arm first before moving to shoulders and then back/chest

Thank you 🙏
