What "Neutral Spine" Actually Means

(And Why It's Not What Most People Think)

I was on the phone with my dad recently — Dr. Jeff Saal, physiatrist, co-founder of SOAR Spine & Orthopedics, and the person I call when I need to think through just about anything — going over an upcoming consult with one of his patients.

He described her goal in two words: controlled neutral.

I wrote it down. Because that's it. That's the whole thing. That's what we're working toward, and it's a better description than anything I've come up with in years of teaching.

First, what neutral spine actually is

Neutral spine is not a position. It's a range.

It's the place where your spine sits in its natural curves — the gentle inward curve at your lower back, the outward curve at your mid-back, the inward curve at your neck — without being forced in any direction. Not flattened. Not exaggerated. Just... home.

I recently wrote about challenging the pesky "flatten your spine" cue that shows up constantly in fitness and yoga classes. The short version: flattening the lumbar spine is not a neutral position, it's a correction in the opposite direction, and for many people it's just as problematic as the excessive arch it's trying to fix. If that resonates, this post is the next chapter.

Because finding neutral is only half the work. The other half — the part my dad summed up so cleanly — is learning to control it.

Why "controlled" is the word that matters

Your spine moves out of neutral constantly. All day. Every time you reach behind you to grab a grocery bag from the back seat, bend down to tie your shoes, turn to look over your shoulder, pick something up off the floor. That's not a problem — that's just being a person with a body who does things.

The problem is when there's no home base to return to. When the spine doesn't know where neutral is, can't find it automatically, and has no muscular support to stabilize it when it gets there. That's when the reaching and bending and twisting become the moments that cause trouble.

Controlled neutral means: you know where your neutral is, you can get there, and you have enough stability and strength in that position to use it as a reference point — a homing beacon — for everything else your body does.

It's not about staying in neutral forever. It's about having somewhere to return to.

It's also not the same for everyone

This is the part that tends to get left out of the conversation.

Neutral spine is individual. Your neutral is determined by your anatomy — the shape of your vertebrae, the natural curvature of your spine, your hip structure, your history. Someone with a naturally pronounced lumbar curve has a different neutral than someone whose spine runs relatively flat. Someone who has had a spinal fusion has a different relationship with neutral than someone who hasn't.

This is why generic cues — "tuck your pelvis," "lengthen your spine," "find a flat back" — are so hit or miss. They're describing someone's neutral. Not necessarily yours.

Finding your neutral requires a little investigation. Which is not as complicated as it sounds.

Try this now: finding your neutral on the floor

The floor is one of the best teachers you have access to. Gravity does some of the work for you down here, and the ground beneath you gives your nervous system something it doesn't always get in standing — clear, immediate feedback about where you actually are in space. That information is useful. Let it in.

Lie on your back with your knees bent and your feet flat on the floor, relatively hip-width apart. Let your arms rest at your sides.

And then just... stay there. That's it for some of you, and that's enough. Let the floor hold you. Take slow, smooth breaths and notice where your body settles. Where your lower back lands. Where the weight of your pelvis rests. Whatever position your spine finds in a relaxed, pain-free state — that's useful information. That's your starting point.

If you're comfortable there and movement feels accessible, you can take it one step further. On your next inhale, notice if your lower back naturally lifts slightly away from the floor. On the exhale, notice if it softens back down. You're not forcing anything — you're following the breath and seeing if there's a tiny, subtle shift already happening on its own. If there is, let it. If there isn't, don't manufacture one.

These movements are small by design — if you're expecting something dramatic, you're doing too much. For anyone whose spine has opinions about bending in either direction, stay well within a pain-free range. The information is in the subtle end of the movement anyway. Less is more here, and that's not a disclaimer, it's the actual instruction.

What you're looking for — whether you moved or simply rested — is the place where your spine feels neither forced nor braced. Somewhere it can just be. That's in the neighborhood of your neutral.

Why this matters more than most of what gets taught in group fitness

Most group fitness cues are designed to work for the most people in the room at the same time. Which means they're approximate, out of necessity. They're a starting point, not a destination.

If you have a history of back pain, a disc issue, stenosis, post-surgical changes, or really any reason why your spine has been a topic of conversation with a medical professional — “approximate” is not going to get you where you need to go. You need to know your neutral. And you need to be building strength and stability there specifically.

That's what SAAL Yoga Fundamentals is built around. Not generic alignment cues handed down from a flow class. A methodical, daily practice that starts with finding your baseline and builds from there — informed by decades of spine physiatry research and designed for people who need more than a one-size-fits-all answer.

If you're already in Fundamentals, this is the principle underlying everything we do in the program. Every cue, every transition, every modification exists to help you find your neutral, recognize when you've left it, and build the stability to return. If the concept of controlled neutral is clicking for you right now, bring that awareness into your next session. It changes what you're paying attention to.

If you've been thinking about starting — this is a good week to do it. Fundamentals is here.

One more thing

Controlled neutral is a goal, not a starting point. Most people walk in the door without it and spend the first chunk of time just learning to find it consistently. That's not a setback — that's the work.

The goal is a spine that knows where home is. So that when life asks it to reach, twist, bend, and carry — and it will, constantly — it has somewhere to come back to.

P.S. A few things before you jump in: if you're a SOAR Spine & Orthopedics patient, you have a 40% discount waiting for you. If you're in an acute phase right now, or dealing with daily sciatica or leg pain, Fundamentals isn't the right starting point yet — but that doesn't mean we can't talk. Schedule a free consult and we'll figure out what the right next step actually looks like for where you are now.
