It’s day 1, and I feel like I don’t want to walk right now. For some reason, I feel like I’m out of my comfort zone. I’m dealing with a flurry of thoughts that want to keep me at home. It’s like a part of me doesn’t want to go on a walk, even though what I truly want is to be healthier.

But why?

Why does it feel so hard to get myself to exercise? To do something as simple as walking?

I haven’t even gotten out the door yet, but this same handful of mental rebuttals is draining my energy. They keep crashing down on me like waves against cliffs, each one taking a turn chipping away at my energy.

I had planned to start walking today. But these tiny resistances are staggering my will to get in my truck and drive to the park. I planned to start walking from a local city park trail that I’ve traversed tons of times in the past, so why do I feel so much resistance?

Here are a few of the thoughts cycling through my head right now.

Am I hungry? Should I eat right now?

I don’t feel like eating, but for some reason, I keep thinking I should make breakfast before I go on my walk. My mind is weighing the option of eating before or after the exercise, and it’s leaning toward now instead of later.

But I know if I eat now, I’ll just end up sitting around until my food settles.

Now I’m concerned about seeing people on the trail. Why?

I love seeing people on trails, or anywhere for that matter, but right now I want the trail to myself. For some reason, anxiety is making a big issue about seeing other people. It doesn’t make sense. This feels like another excuse not to go.

It feels a little cold today, and it might even drizzle with all these clouds.

I’m wearing thin, loose pants and a light short-sleeve shirt. It’s the outfit I picked yesterday. But I’m thinking I should stay home because I won’t feel warm enough. This is weird because I could simply put on a light jacket, but my mind raced toward the idea of staying home instead.

Do I need to go to the bathroom now?

I’m in the truck, and I feel like I should have gone earlier. But I didn’t need to go then. Should I go back home?

But if I do, I’ll waste more time, and I might get distracted by other little things that will steer me away from walking today.

Perhaps I should stay home and work on business tasks, finances, or emails.

There’s a laundry list of tasks I do every day, and right now I feel like I should do that instead of walking. That means I would sit at the computer for a couple of hours, feel drained, and then lie down to rest. But really, I’ll scroll social media for an hour and feel even more tired from all that screen time.

If I do this, I’ll spend (or waste) multiple hours before taking a long nap. Then, by that time, I won’t even bother going on the walk.

These are just a few of the thoughts that are constantly recycling through my head. No matter how many times I bat each resistance down, they spring back up to test my resolve again. Each time, draining a little more energy from me, and further making me want to stay home and rest.

It's learning to ignore the mental arguments that are determined to keep me at home, on the couch, scrolling on my phone.

For most of the drive to the park today, I was contemplating whether I should go on the walk or go back home. It felt like everything was conspiring to stop me — or at least, everything was turning into an excuse not to exercise.

It’s absolutely confounding to me how tiny things that mean nothing can turn into another wave of challenges that try to stop me. For example, when I arrived at the park with all these recycling, clashing thoughts, I added one more by thinking, “Where should I park?”

Where should I park?!

Why is that even a concern? The whole parking lot is empty! There’s probably like 200 empty parking spots, and I’m draining mental bandwidth about where I should park?

And it wasn’t just a question. It added to the reasons I felt like I should go home.

This is when I realized how ludicrous these mental resistances really are. Something that is no problem at all can become another obstacle you have to hurdle just to do something you want to do.

In this case, it was walking for the sake of improving my health.

In this article, I’ll share what it was like to start my "10,000 steps a day for 30 days" challenge. I'm currently on day 15, and staying consistent has been tougher than I expected. The hardest part was the first three days, and that's exactly what this post is about.

My goal is to give you a clear view of what goes on inside our heads and why we make choices we later regret. We’ll look at the mental resistance that makes it hard to start exercising, along with practical ways to push through it. In the end, it all comes down to our habits.

After that first walk, I kept coming back to the same question: why was it so hard to get myself to start walking? I wasn't tired. I wasn't injured. I had the time. So what was actually going on in my head?

It turns out what I experienced has a name in behavioral psychology — status quo bias. It's the brain's tendency to prefer the current state of things over change, even when the change is clearly beneficial.

Our nervous system is wired for energy conservation. Historically, unnecessary movement was a genuine threat to survival, so the brain learned to flag unfamiliar physical effort as a potential risk and send signals designed to make you stay put. This way you can save energy for situations that actually mattered, like finding food, escaping danger, and surviving harsh conditions.

Andrew Huberman, a neuroscientist at Stanford, calls it limbic friction — the internal resistance your nervous system generates when you try to start a behavior that conflicts with how you're currently feeling. It can go two directions:

Either way, the result is the same. Your brain stubbornly holds the line and resists the shift. And since the nervous system is wired for energy conservation, any unfamiliar physical effort gets flagged as something to avoid. The same biological circuitry that once protected our ancestors from wasting energy on losing battles was now making it genuinely hard for me to pull out of my own driveway.

But what about the excuses?

In the moment, every single one of them felt legitimate. The cold. The people. The bathroom. The work emails. None of it was made up. All of these things were worth considering.

That's because the brain is a master rationalizer. Psychologist Jonathan Haidt describes the mind as an elephant and its rider: the emotional elephant (instinct, habit, the desire for comfort) goes where it wants, and the rational rider invents explanations to justify the direction after the fact.

This means I didn't decide it was too cold and then logically conclude I shouldn't walk. My brain had already decided it didn't want to walk, and then went looking for reasons to prove it.

In other words, the brain decides it doesn't want to act, and rationalization finds the justification.

Psychologists call this post-hoc rationalization.

Knowing that, there's actually something useful you can do with it. Research on coping planning — identifying potential barriers and deciding how to respond before they arise, consistently shows that people who anticipate their excuses in advance are significantly more likely to follow through on planned exercise.

This is the core insight behind Peter Gollwitzer's implementation intentions work. If you pre-decide your response to each excuse, you take away rationalization's power before it even shows up. The excuses will still come. But they can be outwitted.

My solution is to write these questions down on paper and write answers that dispute the excuses. Then, when my rational mind tries to find reasons to go back home, I can pull out the note and read the prewritten responses to myself. It seems kind of silly, but it helps.

The social anxiety piece was the one I struggled to understand most, because it didn't match how I actually feel about people. I like running into people on trails. So why was the thought of seeing strangers at the park turning into another reason not to go?

Researchers describe this as anticipatory anxiety, a kind of free-floating unease that doesn't have a real source, so it attaches itself to whatever is nearby. It wasn't really about the people on the trail at all. The anxiety just needed a metaphysical host to latch on to.

Then, when I started walking, within about eight minutes, all of it was just gone. All of the thoughts vanished, no longer trying to stop me from continuing the walk.

But why?

A 2020 study in the British Journal of Sports Medicine found that a single session of moderate-intensity walking measurably reduces anxiety and negative mood within the first ten minutes. The body starts releasing endorphins, cortisol drops, and BDNF, a compound linked to mood and cognitive function, which begins to increase with sustained movement.

So, it turns out that the more I walked, the better I felt.

That left me with one more question. Is this resistance going to show up every time, or will it eventually go away? Because I don't want to fight this mental battle every day. It gets very exhausting.

Research on habit formation, including work by Phillippa Lally at University College London, shows that on average it takes 66 days, not the commonly cited 21 days, for a new behavior to become automatic.

During those first weeks, the prefrontal cortex is doing heavy lifting to override the brain's default patterns. The resistance will show up again. But here's what I discovered after walking beyond the third day: it gets easier each time you successfully make the effort to exercise each day.

James Clear writes in Atomic Habits, "You do not rise to the level of your goals. You fall to the level of your systems." The goal isn't to feel motivated every day. The goal is to build a system where starting becomes smaller and easier, until one day, you're habitually going on a walk without even thinking about it.

For me, that was day 4. I’ll explain more about it in the next article, but I’m basically showing up to walk every day now without having these difficult mental battles like in the first three days.

Part 1 showed how loud the resistance can get, and Part 2 explained why it happens. Now comes the part that actually changed everything for me. It’s a few simple systems that make it easier to start, even when I don’t feel like it.

None of these remove the thoughts completely, but they shrink them down to something manageable so I can take the first step and let momentum do the rest.

I marked my favorite ones with star emojis.

Each day that I go on a walk, especially in the first three days, it gets harder and harder to exercise if I wait too long to start. The biggest barrier is not the walk itself, but the time it takes to begin. So I need to reduce the time between getting dressed and taking my first steps.

In Atomic Habits*, James Clear calls this the 2-Minute Rule: scale any new habit down to something that takes two minutes or less. His classic example for exercise is simply "put on your shoes." For me, that meant "put on my shoes and get in the car." That is it. The rest will follow naturally.*

Once I’m in the car, I can distract myself with music till I arrive at my local park, my starting point.

James Clear also suggests to "Standardize before you optimize. You can't improve a habit that doesn't exist."

So, I standardized my system of picking clothes, choosing my starting point, where I will park my car, and the route I will take the day before. That way, I can wake up the next day and minimize the energy it takes to go for my walk.

Before you get out of the car, you should already know the excuses that are coming. For me, that was cold weather, too many people, working on business, eating breakfast, and uncertain parking. The challenges seem to be the same.

Research on implementation intentions (developed by psychologist Peter Gollwitzer) shows that pre-committing to an "if-then" plan dramatically increases follow-through. For example: "If it feels too cold, then I will wear a light jacket I left in my car." Studies show this simple mental plan can double or triple the likelihood of completing a goal behavior.

Something strange happened once I actually started walking. All the resistance, the cold, the thoughts about going home, the anxiety about the parking lot, just stopped. Not gradually either. It stopped within the first few minutes of walking.

That was something clearly important, telling me that the problem was never my body. My legs were fine. My lungs were fine. The whole fight was happening in my head, and my head was losing it before I even took a single step.

This is the foundation of somatic psychology, the field of research that examines how physical movement shapes mental and emotional states, not only the other way around. We tend to assume the sequence goes: feel motivated, then move. But the research suggests the opposite is often true.

James-Lange Theory of Emotion

William James, one of the founding figures of modern psychology, proposed as early as 1884 that our emotional experience is shaped by our physical actions. He argued that the traditional assumption is that something happens, we feel an emotion, and then our body reacts. You see a bear, you feel fear, and your heart starts racing.

James and his contemporary Carl Lange flipped this on its head. They argued that the physiological arousal happens first, and the "emotion" is simply the label our brain gives to those physical sensations. As James famously wrote: "We feel sorry because we cry, angry because we strike, afraid because we tremble." The experience of the emotion follows the physical response, not the other way around.

Applied to exercise, this means you don't need to feel ready before you start. Starting is what creates readiness. The moment I began walking, my nervous system recalibrated. Motion gave my brain new information to work with, and the resistance lost its grip.

When the resistance shows up, don't negotiate with it. Just start moving.

There’s so much free time to do things while walking. I had a few other small tasks for the day, like grocery shopping, and I realized I could place an order while I was out exercising. That way, I could handle a task while still committed to my walk.

I also listened to podcasts on topics I find interesting, mostly about health.

Throughout the walk, I was able to think freely and clear my head of ideas and questions I would normally ponder while sitting at home.

Normally, these three tasks would eat up a chunk of my day separately, leaving me more drained and less likely to exercise. But out on the walk, I was doing all of them at once, and none of it felt like extra work.

That's the idea behind habit stacking, attaching things you enjoy or already need to do to a habit you're trying to build, so the whole thing becomes easier to start and stick with.

Researchers formally call this temptation bundling, a concept popularized by behavioral economist Katy Milkman at the Wharton School. Her research found that pairing an effortful task (exercise) with an enjoyable one (music, errands, creative thinking) significantly increases long-term adherence. Her studies showed that people who bundled audiobooks with gym sessions were 51% more likely to exercise consistently.

A 2016 meta-analysis published in Psychological Bulletin by Harkin, Webb, and colleagues, reviewing 138 studies, found that monitoring goal progress was one of the most effective self-regulation strategies for changing behavior — including physical activity. The effect was even stronger when progress was physically recorded. It wasn’t gym memberships or coaching, it was simply watching your own numbers.

So I built a full tracking system around this challenge. My Amazfit T-Rex 3 Pro captures steps and distance automatically throughout every walk. Strava logs the full route with splits and pace. After each walk, I pull those numbers into a habit tracker I built in Notion, where I also log my mood before and after, sleep quality, hydration, and body weight. Over time, it all feeds into visual charts that show trends, averages, and where I'm ahead or falling short. It’s a personal dashboard that keeps me honest with my walking challenge.

What surprised me most was seeing the data from Day 1 laid out plainly:

On a cloudy day when I almost turned the car around, when every excuse in the world was cycling through my head, I walked nearly four miles and came home feeling 40% better than when I left.

The numbers do something that motivation alone can't. They give you undeniable proof from your walking results. The thing is, I can talk myself out of a walk pretty easily. But when I open that tracker and see what I've already done, it gets a lot harder to find an excuse good enough to justify skipping out.

Day 1 taught me that the walk itself was never the hard part. The hard part was actually the time before the walk— getting dressed, getting in the car, driving towards the park, parking, the cold weather, or any other little tasks.

Once I was on that trail, nothing mattered anymore. All the excuses that kept recycling through my head completely disappeared a few minutes into my walk.

If you want to exercise but keep finding reasons not to, know that the resistance you feel is common among many of us. You just have to get yourself out of the door first. Everything gets easier after that.

In the next article, I'll share why I decided to start this 10,000 steps a day challenge in the first place. The reason might even surprise you.

Thanks for reading. I'll see you in the next one.
