Habit Stacking: The Sneaky Secret to Building Better Routine

(Inspired by James Clear’s Atomic Habits)

Atomic Habits by James Clear is more than just a book on habit formation—it’s a blueprint for building sustainable, life-changing routines. Clear’s approach focuses on the power of small, incremental improvements—1% better every day—which, when compounded, lead to transformative results.

You know how brushing your teeth doesn’t require a motivational speech every morning? That’s because it’s already part of your routine. Imagine if building new, healthy habits could feel just as automatic.

Enter habit stacking—a concept popularized by James Clear in his bestselling book Atomic Habits. It’s simple, powerful, and borderline sneaky in the best way possible.

What Is Habit Stacking?

Habit stacking is the art of linking a new habit to one you already do regularly. Instead of relying on sheer willpower or setting reminders that fizzle out, you anchor your new habit to an existing behavior—essentially riding the coattails of routines that are already wired into your brain.

Clear explains it like this: “The best way to build a new habit is to identify a current habit you already do each day and then stack your new behavior on top.”

Think of it as using your brain’s autopilot to your advantage.

How Habit Stacking Works

Here’s the magic formula:

“After [current habit], I will [new habit].”

Examples:

• After I pour my morning coffee, I will meditate for 60 seconds.
• After I brush my teeth, I will floss one tooth (yes, just one—you’ll probably do more).
• After I lace up my running shoes, I will do 10 jumping jacks.
• After I close my laptop for the day, I will write one sentence in my journal.

The key is specificity and consistency. You’re not just saying “I’ll meditate sometime tomorrow.” You’re saying when and where—and you’re tacking it on to something you already do without fail.

Why It Works

Habit stacking works because it:

• Reduces decision fatigue: You don’t have to think about when to do the new habit.
• Leverages existing routines: Your brain already recognizes the “trigger,” making adoption smoother.
• Feels manageable: Starting small (as Clear insists) builds momentum and confidence.

Start Small, Stack Smart

The biggest mistake people make? Trying to stack huge, ambitious habits right out of the gate. Start tiny. Even embarrassingly tiny. One push-up. One sentence. One deep breath. The goal is not intensity—it’s consistency.

Then, stack smarter:

• Choose a current habit you do reliably every day.
• Match it with a habit that logically fits (e.g., hydration after brushing your teeth).
• Keep it short and friction-free.

Habit Stacking for Endurance Runners 🏃‍♀️🏞️

For endurance training, the principles in Atomic Habits are incredibly impactful. Clear’s method of habit stacking allows you to anchor important training habits to existing routines. For example, linking hydration to your morning coffee ritual or stretching to your post-run cooldown makes these critical habits almost automatic. Over time, these tiny adjustments stack up to major improvements in consistency, recovery, and mental resilience.

If you’re an endurance runner, habit stacking can be an absolute game-changer for consistency, recovery, and mental toughness. Here’s how you can stack smart habits into your running routine:

Before Your Run:

• After I put on my running shoes, I will drink a full glass of water.
• After I start my GPS watch, I will do two minutes of dynamic stretching.
• After I lock my front door, I will visualize my route and goals for the run.

During Your Run:

• After each mile marker, I will check my form (posture, foot strike, breathing).
• After every aid station (if you’re racing), I will take a deep breath and reset my focus.

Post-Run Routine:

• After I take off my shoes, I will do 5 minutes of stretching.
• After I rehydrate, I will log my run and reflect on how I felt.
• After I shower, I will spend 2 minutes foam rolling.

Final Thoughts

Habit stacking turns the intimidating mountain of self-improvement into a series of tiny, winnable steps. Whether you’re training for a marathon, trying to read more, or just want to finally stretch your hamstrings—habit stacking can help you build a foundation for lasting change.

For endurance runners, it’s a secret weapon for making the critical elements of training—hydration, stretching, and reflection—part of your autopilot.

As James Clear puts it: “You do not rise to the level of your goals. You fall to the level of your systems.”
Habit stacking helps you build those systems, one small step at a time.
