Walk More, Die Less: Our Neuro Nook Recap of Walk 👟

What a way to close out year three of the Neuro Nook (Book Club)! For the first time in our club’s history, we welcomed TWO authors together in one conversation: Dr. Courtney Conley, DC, and Dr. Milica McDowell, DPT, the brilliant brains behind the USA Today national bestseller 📘Walk: Rediscover the Most Natural Way to Boost Your Health and Longevity—One Step at a Time.

(Yes, I took notes while on my walking pad. It felt only right. Honestly, this is how I prep for all of our book clubs. First, I read and highlight the books with my yellow highlighter and 4-colored pen—aka my ‘Swiss army knife’ tools for learning, which are readily available in my purse and laptop bags at all times. Then, I walk and type my notes. Heather and I meet to plan things out. And finally, our monthly group gathers, and we have a proper chat. Oh yeah, then I return to Substack to do our Neuro Nook book recap.)

In full transparency, I had pages and pages and pages of notes from this book. It came at a time when walking was top of mind for supporting loved ones in my life, too.

So, I utilized AI to help me avoid overlap from the podcast transcript, my notes, and the things I wanted to share. I also aimed to add the important parts from my notes that I highlighted, starred, and had in nice bold font, which indicated to me they were very important… so here we go!

The full author conversation drops as a podcast episode on July 22 — but this recap includes something the podcast won’t: the exclusive live Q&A our attendees got with the authors at the end of the session, plus a deep dive into the book’s science that we simply didn’t have time to cover live.

What’s This Book About❓

What James Nestor did for breathing, Dr. Courtney Conley, DC and Dr Milica McDowell DPT do for walking. Their argument is simple and a little radical: walking isn’t just exercise. It’s a physiological necessity — as essential to survival as breathing and sleeping. And yet we’ve nearly engineered it out of modern life.

The book restores walking to its rightful place as a pillar of health, backed by the most current research, self-assessments, footwear guidance (prepare to look at your shoes very differently), “movement snacks” to break up sedentary days, and customizable walking programs for every level.

Nobody talks about breathing until breathing becomes a problem. Sound familiar, walking?

👟“Vitamin W (Walk) plays a critical role in supporting and improving your overall health.”

💌 Words From The Author:

“Without consistent movement, our brains and bodies will not function at their highest capacity, and without movement variability and adaptations, we cease to move forward.”

💭 Reflection Questions for Real Life Integration

• How do you know when your body is hungry for movement?

• We need to ask ourselves: what’s happening to walking, and why is it disappearing from our lives?

• Have you ever thought about how modern conveniences such as remote work and digital communication further decrease our chances of walking each day?

• What if you thought of walking as a daily vitamin, an essential dose of movement your body needs to function at its best?

• What kind of health benefits are you personally seeking, and can you get them by adopting a walking practice?

• What is pain, and how do you define it?

• Now review your definition and take a moment to consider the following aspects:

• How do you define pain?

  • What influenced your definition?

• Which of your experiences would you consider painful, and how did they affect your life?

  • How long did you deal with them?

  • What coping strategies did you use? Did they work?

• Will you set up your super small goal of a micro walk to break up your work day, and then celebrate your tiny win?

• Will you opt for shoes that make walking easier, knowing that they may also weaken your feet?

💡 Key Concepts & Insights: How to Walk

Vitamin W. The authors prescribe walking like a daily vitamin — an essential dose of movement your body needs to function at its best. Deficiency symptoms are real.

The 10,000-steps myth is officially busted. That number was never based on science. Here’s what the research actually says:

• 2,500 steps/day is the absolute basement number for anyone able to walk

• 3,500–8,500 steps/day is where meaningful health benefits live

• 7,000–8,000 steps/day is the sweet spot Dr. Conley gives her patients to maximize longevity benefits

• 5 minutes ≈ 500 steps — the definition of a “micro walk,” and yes, it counts

Speed matters as much as steps. A brisk pace is roughly 112–130 steps per minute (about 3.5 mph on a treadmill). Faster walking engages your muscles in a more coordinated pattern and distributes forces more evenly across the body — which is why, counterintuitively, walking faster can actually reduce knee, hip, and low back pain.

“Roll the earth away.” The authors’ favorite cue for efficient walking: your heel grazes the ground, your body rolls forward through the outside of the foot toward the big toe, and you push the earth behind you. And here’s the part I can’t stop thinking about — walking is a rotational movement. Swing those arms. That’s free energy.

Your foot is the Texas of your brain. 🤠 Dr. McDowell’s analogy stole the show: the foot occupies some of the largest real estate on your brain’s sensory map — everything’s bigger in Texas. Your feet are constantly megaphoning information to your brain about balance, position, and safety. Healthy feet = clear signal. Overly cushioned, restrictive shoes = static on the line.

🦶 Your Toes Might Be the Secret to Not Falling

Since we’re talking feet: falls are the leading cause of injury-related deaths among adults 65+, and one in four adults over 65 reports a fall each year. Here’s what the research highlights that almost nobody talks about: it’s often toe weakness — not overall muscle weakness — that’s a key factor in falls.

Some perspective on what your feet handle: the big toe bears 30–50% of your body weight during the push-off phase of walking. It’s the main gas pedal propelling you forward.

And your riskiest moment in any walk? The very first step.

Two tests from the book to try at home:

1. The tripod check. Stand and feel for pressure at three points: the base of your big toe, the base of your little toe, and the center of your heel. That’s your foot’s ideal load-bearing tripod.

2. The single-leg balance test. Can you stand on one leg for 10 seconds with your eyes closed? Closing your eyes removes visual input and forces your vestibular and proprioceptive systems to carry the load. (Stand near a counter. Humble yourself safely.) Then, try the other leg. Compare your experience between the two sides—they are likely different.

Then meet toe yoga: lift just your big toe while keeping the others down, then lift the other four while your big toe stays planted. As Dr. McDowell warned us, it sounds easy until you take your shoes off and try it. (She was right. I checked. My toes and I are in negotiations with assistance from my hands until my brain learns the tasks.🫠)

“Toe Yoga”

Sit comfortably barefoot or try standing near a countertop or chair for safety.

Try to keep your four smaller toes flat on the floor while lifting only your big toe.

Next, keep the big toe flat and lift the four smaller toes.

Do this 10 times on each foot.

(Note: This requires intense focus and will feel frustrating at first—that is completely normal!)

🔄 Walk Backward to Move Forward (Yes, Really)

Here’s my favorite brain-bending nugget from the book that never made it into our conversation: walking backward improves your forward walking.

Retro walking (that’s the official term — you’re welcome for your new party fact) results in improvements in balance, body awareness/proprioception, lower body and spinal muscle strength, and — most surprisingly — your forward walking pattern.

Why does it work? Backward walking presents a brand-new challenge for your brain and neuromuscular system: a novel movement pattern to solve, new coordination puzzles to crack. For those of us who love cognitive engagement (hi, it’s me 👋), this is movement and brain training in one. It can also be beneficial for people managing low back, knee, or ankle pain.

Start small, somewhere safe and flat, and maybe not on your first coffee of the day. ☕

⏱️ How to Measure Your Walking Cadence (Try This Today!)

Gait speed is now considered the 6th vital sign — right up there with heart rate, blood pressure, breathing rate, body temperature, and oxygen levels. Unlike those, this one you can test at home, for free, today:

1. Set a timer for 1 minute and walk at your comfortable, everyday pace.

2. Count each time your RIGHT foot hits the ground.

3. Multiply by two. That’s your cadence in steps per minute.

4. For accuracy, repeat this 3–5 times throughout the day (same shoes!) and average your scores.

What your number means: Most adults average around 100 steps per minute. A brisk, health-promoting pace is 120–130+ steps per minute. If you’re below that, don’t panic — train it.

Dr. Conley has patients use a metronome app: if you’re living at 110, bump it to 115 and match your steps to the beat. Her patients’ most common reaction? “That was actually easier.” Efficiency for the win.

Changes in your cadence over time can also serve as an early warning sign worth discussing with your healthcare provider — which brings us to...

🧠 Walking & Your Brain: Dementia, Memory, and Mood

More walking → less dementia. Dr. McDowell walked us through what she called excellent science — a study of nearly 80,000 adults followed for seven years:

• Walking ~3,800 steps/day (about 2 miles) = 25% lower dementia risk

• Walking ~9,800 steps/day (about 5 miles) = 51% lower dementia risk

Her takeaway: if dementia runs in your family, aim toward the higher end of that range. This is a risk factor you have real control over.

The 7-year window. A slower gait has been detected up to 7 years before the onset of dementia (some newer research suggests up to 9). Seven years. That’s not a scary statistic — that’s an opportunity!

Memory bonus most people miss: one of my favorite research nuggets from the book — your walking posture can shape emotional memory and how you process the world around you. Walk taller: shoulders back, head level, spine stacked. And regular walking of more than 2 hours per week can stabilize or even improve cognitive decline in early-stage Alzheimer’s. That’s less than 30 minutes a day.

Mood is dose-responsive. Dr. Conley shared that patients walking under 2,500 steps/day almost always arrive with symptoms of low mood. The research staircase:

• 5,000+ steps/day → reduced symptoms of depression

• 7,000+ steps/day → reduced risk of developing depression

Her clinical approach for patients in chronic pain? “Microdose” the movement. Five minutes. Build safety. Then climb.

🧩 The Pain-Brain Connection: Why Walking Changes Your Chemistry

One of the most fascinating threads in Walk is how thoroughly pain lives in the brain — not just the body.

The brain regions that process physical pain are the same regions that regulate mood and emotional responses. That’s why the relationship runs both directions: in a study of nearly 350,000 people, 39% of those with chronic pain had clinical symptoms of depression, and 40% had clinical symptoms of anxiety. Depression and anxiety actually lower your pain threshold — a process called hypersensitization — making you physically more sensitive to painful stimuli. Chronic pain also depletes serotonin and dopamine, the “happy hormones,” compounding the gloom.

Walking interrupts this cycle from multiple angles. It boosts those feel-good hormones — the authors put it beautifully: walking essentially improves your chemistry. And the counterintuitive prescription that stopped me in my tracks: if you have knee, hip, or low back pain, don’t slow down — speed up. Increasing your walking cadence just 20% (aiming for 120–130+ steps per minute) may meaningfully reduce knee pain, with very little downside to trying.

The book also introduces a brain-training companion practice: observing your pain with curiosity and without fear. Being a gentle, neutral observer of the signals your brain is sending can reduce its threat signaling. Simple, not easy — but the authors call walking plus brain-retraining strategies “a powerful one-two punch.”

(The usual reminder: this is education, not medical advice — talk to your own healthcare provider for your specific situation.)

🔬 The Science We Didn’t Have Time For: Walking & Cancer Risk

We spent our time with the authors on the brain — but the book’s cancer findings deserve their own spotlight, because the numbers are genuinely jaw-dropping.

Speed matters: Individuals who reported walking around 4 mph had dramatically lower risks for five types of cancer compared to slower walkers — including a 70% lower risk of anal cancer, 61% for liver, 54% for small intestine, 50% for thyroid, and 40% for lung.

Steps matter too: In one study of 85,000 adults, increasing daily steps from 5,000 to 7,000 was associated with an 11% lower risk of developing 13 specific types of cancer. Push to 9,000 steps, and that drops further to 16%. The difference between 7,000 and 9,000 steps? About 20 more minutes of walking. That may be the best return on 20 minutes you’ll find anywhere.

Keep it simple. 5 minutes of walking is about 500 steps. Where can you add this into your day? Think about it. Get creative. And walk 5 minutes at a time.

😴 And Don’t Forget the Trilogy: Walk Your Way to Better Sleep

Remember the trilogy — walk, breathe, sleep? The book confirms walking is a reliable ally for better sleep, with influence extending far beyond simply tiring you out. And the dose is refreshingly achievable: you just need to walk more than your current average. No perfect number. Just more than yesterday. That might be the most forgiving prescription in the whole book.

📈 Level Up Your Walk: Two Upgrades Worth Trying

👃 The free upgrade: nasal breathing. Full-circle moment for longtime members of the Neuro Nook (Book Club): we launched this book club early on with Breath by James Nestor, and Walk brings the two together. Breathing in and out through your nose with diaphragm support while walking boosts tissue oxygenation, improves walking efficiency, and helps shift your body into a reduced-stress state.

Start with small increments — up to 5 minutes of nose-only breathing — and build from there. (And if you need to open that mouth, of course, please do!) As performance breathing expert Brian McKenzie puts it, the lowest-hanging fruit in human metabolism is a long walk with your mouth shut.

🎒 The weighted upgrade: rucking. Walking with a weighted backpack is having a well-deserved moment. Each step of regular walking already sends 4–6x your body weight through your feet; adding load amplifies the training effect. The research-backed benefits include improved cardiovascular function, strength and endurance, increased calorie burn, bone density support (especially relevant for those of us thinking about long-term bone health), and — my favorite — improved mental toughness.

The authors’ guidelines: start with 5–10% of your body weight, keep it below 30%, and shorten your walks while your body adapts. You’re essentially stacking a strength session on top of your walk — efficiency my calendar can respect.

You can learn a lot more about this on author Michael Easter’s Substack. His name might be familiar to you since we explored his book “Scarcity Brain” in the Neuro Nook (Book Club) in April 2025.

🎤 EXCLUSIVE: The Live Q&A (Reader-Only Content!)

This segment won’t appear on the July 22 podcast episode — consider it your reward for reading to the end. Our attendees came with questions, and the authors delivered.

Q: What about house slippers? What should we wear at home for foot health?

Dr. Conley’s answer: Slippers are fine — if they respect the anatomy of your foot. Look for a wide toe box and minimal cushion. Her personal barometer: “Do my toe spacers fit in my house slippers?” (She wears her toe spacers all day.) Her go-to pick: Bombas slippers. Don’t overcomplicate it.

Q: It’s a heat wave. Does housework count toward my steps? What about those “cleaning the house chore = X steps” charts?

Dr. McDowell didn’t sugarcoat this one: sadly, no science behind those charts. There are two kinds of walking — intentional (continuous, rhythmic, rotational) and ambient (up, down, around the house). Ambient movement is better than nothing, but it doesn’t deliver the same benefits as continuous walking. Her heat-wave advice, verbatim: “Suck it up, buttercup” — if you have treadmill access, this is its moment. The heat wave won’t last forever.

🗨️ Final Takeaway Messages from the Authors & Hosts

✍️ Words from the Authors

A few lines from our conversation that deserve to be emphasized:

Dr. Courtney Conley, DC: “Take your shoes off and look at your feet. It is one of the most forgotten parts of our body that literally is one of the most important in carrying us through life.”

Dr. Milica McDowell, DPT: “Five minutes counts. The five-minute micro walk has the power to change mood, improve your blood pressure, change your posture, and reset creativity.”

From the book: “Walking has the potential to simultaneously add years to our life and life to our years.”

Fun fact from behind the scenes: Heather and I independently chose the exact same favorite quote out of a 300-page book. Co-host brain waves are real, but Heather accepted the brain challenge to s-t-r-e-t-c-h and found an alternative. (I appreciate you, Heather!) 🙃

Heather, Co-Host of the Neuro Nook:

💭 “Walking is about relationships and wellness. It’s about health and longevity.
It’s about conscious choices that support your physical and mental health.

Walking is a pathway to positive lifestyle change. It’s a tool you can use to become more connected to yourself and others.

When you adopt a consistent walking practice, you take charge of your wellness. And when you encourage and empower others by inviting them to walk alongside you, you can promote positive change in your local and global communities.”

Krystal, Host of the Neuro Nook:

💭 “Spending time purposely is one of the biggest challenges in modern human space. We believe the most purposeful way we can spend our time is to get out and walk.

A walk can feed our relationships, improve our self-confidence, and boost our mental and physical health.

What a gift! Walking has the potential to simultaneously add years to our life and life to our years. Walking is time well spent and a change worth exploring.” (💌 page #118)

Will you join us – and the authors – in their final call to action and promise to keep walking with us? 👣
