Adjustments for vitality. 🪽🪽

The T5-7 zone of thoracic spine is the hardest region in the entire spine to move….
It’s the apex of your kyphotic curve.
The thoracic spine has a wild design.
Twelve segments, ten of them locked into the rib cage on both sides, anchoring the ribs to your sternum. The last two ribs float free, attached to the spine but nowhere else.

Built for stability, not mobility.

Which is exactly why it’s the first place to go stuck…..

And when it goes stuck, you go old. Rounded shoulders. Collapsed chest. The posture everyone associates with age but is really just years of a thoracic spine nobody ever addressed.

Yogis figured this out centuries before biomechanics had a name for it.

Backbends. Wheel pose. Camel. Every deep extension is a direct assault on thoracic stiffness…..

Pair that work with a Chiropractic adjustment and something different happens.

The yoga opens the tissue. The adjustment restores the joint. Two different languages saying the same thing to your spine…..

Move.

And watch the nervous system respond. The sympathetic grip loosens. Fight or flight lets go. The body finally has permission to shift into parasympathetic….. rest, repair, regulate.

And when that region opens, it doesn’t just change your posture. It changes your breath. Full inhales instead of shallow ones. It changes what your chest can do when it’s not collapsed in on itself.

Some people describe it as wings emerging from the spine.

That’s not poetry. That’s what it feels like to finally fly to your full height. Innate expression.

Adjustments for vitality.

Everyone thinks Chiropractic! is for low back pain.

Ask the women in my practice what they actually noticed first.

Shorter cramps.
Lighter flow.
A cycle that shows up on time instead of throwing a surprise party.

Here’s what’s actually happening…..

Your uterus is wired by two separate nerve pathways. T10 through L2 carries the sympathetic supply. S2 through S4 carries the parasympathetic.

When the low back segments lock up, the sympathetic pathway stays switched on. Fight or flight. Tension. Restricted blood flow to the pelvic organs.

When the sacrum locks up, the parasympathetic pathway loses signal. Rest and regulate goes offline right when your body needs it most.

An adjustment restores motion to both regions, which restores accurate signal through both pathways, and lets the parasympathetic system finally do its job…..

Rest. Digest. Regulate. Repair.

Your nervous system was never designed to run a monthly hormonal cycle while stuck in defense mode.

Remove the interference. Let the system talk to itself the way it’s supposed to.

That’s not a period fix. That’s a nervous system fix that happens to fix your period.

First time @baker2g_ came in, I asked her, “Anything funky going on?”

She goes, “Menstrual cramps.”

Like it wasn’t even worth mentioning.

Because everyone thinks Chiropractic is about pain.

Nobody tells you it’s also behind…..

Better sleep.
Fewer headaches.
Easier digestion.
More energy during the day.
Faster recovery between workouts.
A calmer nervous system overall.

Pain is just the thing that gets you in the door.

SCIATICA + CONSTIPATION + FEELING UNGROUNDED

THE OVERLOOKED ROOT: YOUR SACRUM

If you’re stuck with sciatica... sluggish digestion... and you just don’t feel connected to your core... you need to get this checked. Your low back and sacrum.

You’ve probably done the work. GI doctor. Fiber. Magnesium. Stretching. Core work. Maybe imaging or physical therapy. And you’re still wondering what’s next.

Here’s what often gets missed. Your sacrum is the foundation of your spine. It’s where your lumbar spine meets your pelvis.

The sciatic nerve roots exit right here (L4 to S3). And the nerves that supply your lower colon and pelvic floor come from the sacral segments (S2 to S4).

So when the lumbosacral junction or SI joints are stuck, restricted, or unstable... it can affect how that region moves, loads, and communicates. Nerve signaling. Pelvic floor tone. Core stability. Even how grounded you feel in your body.

Your symptoms may not be random. There may be a pattern.

Here’s a quick filter. Do you have:

🫣 A history of falls on your tailbone, wipeouts, car accidents, or sports injuries?
🫣 Long hours sitting?
🤩 Pregnancy or birth history?
☹️ Low back stiffness that flares with stress or sitting?
😫Sciatica that comes and goes, plus digestion that feels slow?

If that’s you, get your low back and sacrum evaluated. A chiropractor who looks at the whole structure, not just where it hurts.

Clubs. Lifting weights is great... but swinging them? Different animal 🔥

Just signed up for a six week @mudgarclub course. I’ll be tracking progress here so you can follow along.

Back in 2019, my brother from another mother Yahel Sharabi of @soulpumpfitness taught me five different swings with the Indian clubs. Now I’m ready to take it to the next level and expand my movement vocabulary.

This is my current warm-up progression. Not the Mudgar progression, that comes next:

🖤 2 lb black clubs: wrist mobility, shoulder openers
💪 5 lb clubs: the first real swings
⚙️ 10 lb steel club: smaller, different arc... didn’t make the cut today
🔥 25 lb Mudgar club: the new one. Heavy.

Everybody waits for January 1 to start fresh. It’s cold. It’s dark. It takes way more willpower. Unless you’re in the southern hemisphere and then the opposite applies. Go crush it.

Fall and spring are the real launch windows. Energy is already moving. Use it.

Six weeks. Let’s go 🙏 by @spinechecker

Still stiff….. still guarded….. still not right?

You’ve done the work… the imaging
Stretching. Strength. Massage. Yoga. Your medical doctor says nothing’s wrong.

Maybe nobody checked the architecture with motion Xrays coupled with a hands-on motion palpation. 🤷🏼‍♂️ Especially the upper neck … the anonymous call it the mouth of God, the cave of the soul, the center of life… where the skull meets the spine…..
one of the most neurologically dense junctions in the body.

When the structure is off, the system compensates.
Jaw. Shoulders. Hips. Sleep. Energy. Recovery. Performance.

Compensation isn’t random….. it’s a pattern.

A neck that’s always a little aching.
Relief that never lasts.

If that’s you….. get your spine checked. I got you.

And if you’re just looking to get cleared out and connected… to stay at the optimize level… we got you too.

Adjustments for vitality.

I call this one the kung fu move…..

Anterior thoracic.

The name comes from the footwork.

I was dialing in block placement height….. trying to get a little more extension than the classic roll down and set the bone.

Hunting for the perfect height for the head to land. @wyatt.hanson is a big powerful human.

Turns out the head didn’t need one.

Nothing about delivering an adjustment is cookie-cutter.

You have to find the right way to enter the field…..
touch the bone…..
and activate the nervous system to facilitate the healing.

The perfect height was never the point….. the entry was.

Find the entry….. the bone does the rest.

Precision isn’t a formula….. it’s a conversation with the tissue.

If your body’s been trying to tell you something and nobody’s listening….. that’s what we do here.

…oh yeah… And while we’re at it, if you wanna elevate your mood with a canned mimosa… Check out his his family business @drinksuntide

New tool for longevity just landed... 🔥

The Mugar Club 10-12 kg (22-26 lbs) from @mudgarclub just arrived from India!

Heavy. Rotational. It loads the shoulders, upper back, and trunk through big ranges most people never touch. Your spine has to organize and stabilize under load while the shoulders move free.

First learned a handful of moves from my friend and movement teacher @aba_son_and_daughter of @soulpumpfitness . Now I’m going deeper with new weight and a 15 video course.

They even engraved my name on it 🙏

Lifelong learner. Always.

First, we got special lights for our front desk from @getchroma.co . Why? Because I want the person serving our people to be energized, especially indoors. We do have great natural light, which is a plus. But the Chroma Sky Portal 2.1 was one of our early non-negotiables.

Next up was the rest of the office. First we had to establish the right temperature: about 2700 to 3000 Kelvin.

We got premium lights. But after about two months in the space, it didn’t feel right.

So we reinvested back into the practice. We’re about to replace them. Coming this Friday, so when you walk into our space on Monday... it’s a new game.

Circadian lights from @thehealthyhome.shop : completely flicker-free, blue-light-free, shifting from clean daylight to a warm campfire glow.

Stay tuned.

People ask what do you do on your lunch break between 12 PM and 3 PM…..

Parallettes. Low bars, about a foot off the ground. Push-ups, L-sits, or my favorite... going airborne.

Chiropractic isn’t just about what hurts.
It’s about how you move, how you adapt, and how you show up in the world.
Get aligned, connected, and energized.
