The Partner Back Stretch
By Dr. Jeremiah Jimerson, DC — known online as Younger You Doc (@youngeryoudoc)
Two versions of this one travelled a long way. It needs a partner, which is unusual for something that spreads online — most people watching won’t have somebody standing next to them. It spread anyway.
A second version of the same idea reached roughly 25.1 million views →
I Didn’t Invent Partner-Assisted Extension
Two people helping each other into extension is about as old as stretching. Variations show up in manual therapy, in gymnastics and wrestling warm-ups, and in yoga.
What I’ve done is refine how it’s set up — where the contact goes, how much the assisting person actually does, and how to keep the person being stretched in control — and then film it in a way that made sense to people who have never had hands-on work.
Most of my day is spent watching what happens when people move. You notice which setups produce a real change and which ones just look impressive. This is one that produced changes consistently enough that I kept using it.
Test It Before and After
Before: stand normally. Bend backward as far as is comfortable — note where it stops and what you feel. Take a slow deep breath and notice how far the ribs move. Bend forward and see where your hands land.
Then: do the maneuver once, slowly.
After: repeat all three. Most people notice the breath first, which surprises them, because they were thinking about their back.
That’s the honest test. If nothing changes, nothing changes — that’s information too.
Why It Might Change Something
Working theory again.
Most people spend the day in flexion — sitting, driving, phones, desks. Extension is the direction the thoracic spine loses first, and the ribs and the tissue around them stiffen along with it. That much is uncontroversial.
What I think is happening is a combination. There’s a mechanical component — you’re moving segments through a range they haven’t seen in a while. There’s a respiratory component, because the ribs have to move for the spine to extend well, which is my guess at why breathing often feels different afterwards. And there’s likely a sensory component: a large, novel input over the back that changes what the nervous system is reading from the area, with some protective tension letting go.
Which of those matters most, I don’t know. I doubt it’s the same for everybody.
What This Doesn’t Tell You
Extension feeling good is not a diagnosis.
Some back pain responds well to extension and some is made worse by it — that difference matters and it isn’t something you can sort out from a video. If your back pain has a clear directional preference, you want to know which direction that is before loading it repeatedly.
And a stretch that helps for an afternoon hasn’t told you why you keep stiffening up. In my office that usually traces to hip mechanics, breathing pattern, or how someone loads one side more than the other. More on what actually drives back pain →
When Not To — Read This Part
This is the only technique on my site where somebody else applies force to your spine, so it gets the longest version of this section. The person helping cannot feel what you feel. That asymmetry is the entire risk.
The rule that matters most: the person being stretched sets the depth and the person assisting never adds to it. No cranking, no bouncing, no pushing through a stopping point, no “just a little further.” If you are the partner, your job is to support the position the other person has chosen and nothing else. The moment they say stop, you stop, mid-movement, without finishing the rep.
Stop and get assessed — do not try this at all. These are red flags that need a clinician before anyone stretches anything:
- Recent significant trauma — a fall, a crash, any impact where a fracture is possible, or a suspected fracture of any kind
- New or progressive weakness in a leg, or a foot that drags or gives way
- New bowel or bladder problems — incontinence, retention, or not being able to tell when you need to go
- Numbness in the saddle or perineal area — the parts that would contact a bicycle seat
- Severe or worsening neurological symptoms — spreading numbness, loss of coordination, symptoms in both legs
- Systemic red flags — unexplained weight loss, fever, night sweats, a history of cancer, night pain that wakes you and will not settle in any position, or any current serious illness
- Substantial osteoporosis or known fracture risk, including long-term steroid use or a previous fragility fracture. Loaded extension applied by another person is a poor idea in a spine that fractures easily.
The bowel, bladder and saddle-numbness combination in particular is a same-day emergency-room issue, not a wait-and-see one. It has nothing to do with this stretch — it is on the list because anyone reading a back-pain page should know it.
Get cleared first — and do not let anybody force the movement. If you have a diagnosed spinal condition, this is not automatically off limits, but it is not something to work out from a thirty-second video either:
- A known disc herniation. Extension helps some people with disc pain a great deal and makes others considerably worse, and which one you are is not something you can guess in advance. Find out from whoever is treating you whether extension is a direction you should be going, and if so, do it under your own power before you involve a partner.
- Spondylolisthesis, spinal stenosis, or a diagnosed instability. Extension is often the provocative direction in these. Ask specifically.
- Prior spinal surgery — fusion, discectomy, hardware. Your surgeon knows what your segments can and cannot do.
- Pregnancy. Not banned, but the ligamentous laxity of pregnancy means a joint can be taken further than it should go without it feeling like much at the time, and the positions here are awkward as pregnancy progresses. Check with whoever is managing your pregnancy, and if you get a yes, keep it gentle and self-directed rather than partner-forced.
- Any inflammatory arthritis affecting the spine, or a connective tissue disorder with hypermobility.
In all of those cases the sentence to say out loud to your clinician is: “is extension through my upper back an appropriate direction for me, and is it safe for someone else to assist it?” A yes to the first is not automatically a yes to the second.
And for everybody: mild stretch is fine. Sharp pain, radiating pain, pain that travels down a leg, or anything that feels neurological means stop and get looked at. Once daily is plenty. If it leaves you sore, it was too much.
Common Questions
Does it realign the spine?
No, and I’d be sceptical of anyone who says it does. It moves segments through a range they haven’t been visiting.
Why does my breathing feel different afterwards?
My working explanation is rib motion — the ribs have to move for the thoracic spine to extend, and freeing that up seems to change how the breath sits. That’s a hypothesis, not a proven mechanism.
Can I do it alone?
Not this version. There are self-directed options over a foam roller or a rolled towel that work in the same direction with less force.
How often?
Once daily is plenty. It shouldn’t leave you sore.
My back cracked. Is that bad?
Usually not meaningful on its own. Cavitation is not the goal and it isn’t a measure of whether anything useful happened.
If Your Back Keeps Tightening
I treat back pain, disc-related pain, SI joint pain and sciatica at my office in West Ashley, Charleston. If a stretch helps for an afternoon and then it’s back, the stretch isn’t the problem — the reason you keep needing it is.
