I’m a certified fitness trainer passionate about sharing evidence-based strategies to help you optimize your training and wellness. Today, we’re diving into a game-changing topic: how to rewire your nervous system to unlock your full potential. Let’s get started!

Your Nervous System: The Command Center of Everything

Your nervous system—comprising your brain, spinal cord, and all the connections to your body—is the master controller of your life. It governs your movements, emotions, thoughts, and even how you adapt to challenges. Unlike other species, humans have the unique ability to deliberately reshape our nervous system through specific actions. This process, known as neuroplasticity, is like upgrading the software of your brain to perform better, learn faster, and adapt to new goals.

In this post, we’ll explore how movement and balance act as powerful gateways to neuroplasticity, allowing you to improve physical skills, enhance cognitive abilities, emotional resilience, and learning capacity. No gimmicks here—just science-backed tools to help you take charge of your brain’s potential.

Does the Brain Control Behavior? (Spoiler: Yes!)

Your brain and nervous system absolutely control your behavior. When it comes to movement, two types of neurons are key players:

• Lower Motor Neurons: Located in the spinal cord, these neurons send signals to your muscles to make them contract. They’re like obedient soldiers, executing orders from above. Fun fact: there’s no such thing as “muscle memory.” Muscles don’t store information—your neurons do, encoding patterns like walking or lifting weights.

• Upper Motor Neurons: Found in the motor cortex (the top of your brain), these neurons send deliberate signals for actions like picking up a dumbbell or performing a squat. Over time, repetitive actions become almost automatic, shifting control to lower brain regions like the brainstem.

Your brainstem also houses central pattern generators (CPGs), which drive repetitive movements like breathing or walking without conscious effort. These systems work together to make your movements smooth and efficient. But how do we use this knowledge to change our nervous system for the better? That’s where neuroplasticity comes in.

Can Behavior Change the Brain? Absolutely—If You Do It Right

Can your actions reshape your brain? The answer is a resounding yes, but only if those actions are different enough from what you already know how to do. Simply going through the motions—like your usual gym routine—won’t cut it. Exercise is fantastic for health, but it doesn’t automatically trigger neuroplasticity unless you introduce novelty and challenge.

The key to unlocking neuroplasticity is making errors. When you try something new and mess up, your brain gets a signal that something’s off, releasing neurochemicals like acetylcholine (for focus), epinephrine (for alertness), and dopamine (for motivation and reward). These chemicals mark neural circuits for change, which solidify during sleep. The catch? You need to embrace the frustration of failure and keep pushing through it.

Why Errors Are Your Brain’s Best Friend

Making mistakes isn’t just okay—it’s essential. When you repeatedly fail at a task (like missing a free throw or stumbling through a new yoga pose), your brain releases chemicals that highlight which neural pathways need tweaking. Classic experiments, like those from Eric Knudsen’s lab, show that errors drive plasticity. For example, when subjects wore prism glasses that shifted their visual field, their brains adjusted by realigning sensory and motor maps—but only after repeated mistakes.

For adults (especially after age 25), plasticity is slower than in kids, but it’s still possible with incremental learning. Instead of tackling a huge goal all at once, break it into smaller chunks. For instance, if you’re learning to deadlift with perfect form, focus on one cue (like hip hinge) for a short session, make errors, and adjust. Aim for 7-30 minute bouts of focused practice where you’re hitting the edge of frustration but not quitting. This signals your brain to adapt.

The Dopamine Hack: Reframe Failure as Progress

Here’s a pro tip: learn to love the grind. Dopamine, the “feel-good” chemical, isn’t just about pleasure—it’s about motivation and signaling that you’re on the right path. By mentally reframing errors as stepping stones to success, you can trigger dopamine release, supercharging your plasticity. Tell yourself, “This frustration is making me better!” It sounds simple, but it’s powerful. Studies, like those in The Molecule of More, show dopamine is highly subjective—what feels rewarding to you can amplify your learning.

The Vestibular System: Your Secret Weapon for Plasticity

Let’s talk about a hidden gem: your vestibular system, the inner-ear mechanism that governs balance. It tracks your body’s orientation to gravity through three planes of movement: pitch (nodding), yaw (shaking your head side to side), and roll (tilting like a curious puppy). When you disrupt this system—like when you try a new movement that throws you off-balance—it signals your cerebellum (the “mini brain” at the back of your skull) to release dopamine, epinephrine, and acetylcholine.

Why does this matter? These chemicals create a brain state primed for learning—not just for motor skills but for cognitive tasks too. Activities that challenge your balance, like yoga, gymnastics, or even skateboarding, can amplify plasticity if they’re novel to you. The key is to step outside your comfort zone. If you’re a pro at handstands, they won’t trigger plasticity anymore. But if you’re wobbly trying a new yoga inversion, your brain is lighting up with learning potential.

Safe Ways to Tap Into Vestibular Plasticity

You don’t need to do backflips to harness this. Here are safe ways to challenge your vestibular system:

• Try a new sport or activity: Pick something unfamiliar, like rock climbing or paddleboarding, that forces you to move in new planes.

• Incorporate balance drills: Stand on one leg while brushing your teeth or try a wobble board at the gym.

• Explore yoga or tai chi: These practices involve dynamic movements that shift your relationship to gravity.

• Mix up your workouts: If you always run, try lateral shuffles or crawling exercises to engage pitch, yaw, and roll.

The goal is to feel slightly unstable (but safe!) to trigger those neurochemicals. Avoid high-risk moves like parkour unless you’re trained—plasticity isn’t worth an injury.

Limbic Friction: Getting Your Mind in the Game

Before you even start a learning session, your mental state matters. Limbic friction is the tension you feel when your autonomic nervous system (which controls arousal) isn’t aligned with your goals. There are two types:

• Too amped up: You’re anxious, heart racing, and can’t focus. Calm down with a physiological sigh (two quick inhales through the nose, one long exhale through the mouth) or widen your gaze to panoramic vision.

• Too sluggish: You’re tired and unfocused. Wake up with a quick burst of super-oxygenation breathing (deep, rapid inhales) or a splash of cold water on your face. Better yet, prioritize sleep or a non-sleep deep rest (NSDR) session.

Aim for a clear, calm, and focused state to maximize learning. Schedule your practice during your peak mental acuity (often morning for most people) to make the most of those error-driven sessions.

High Stakes, High Rewards: The Power of Contingency

One final piece of the puzzle: motivation matters. Research shows that when the stakes are high—like needing to learn a skill to achieve a critical goal—plasticity accelerates. If your brain knows a task is vital (say, mastering a movement to compete or improve your health), it releases more neurochemicals to speed up learning. Create internal urgency by tying your practice to a meaningful “why.” For example, remind yourself that improving your squat form will boost your confidence and prevent injury.

Putting It All Together: Your Neuroplasticity Playbook

Here’s how to apply these principles to supercharge your learning, whether you’re refining a deadlift, learning a new sport, or even tackling a mental skill like meditation:

• Set the stage: Use physiological sighs or energizing breaths to hit that clear, calm, focused state.

• Choose a novel challenge: Pick a movement or task that’s new or slightly unstable to engage your vestibular system.

• Embrace errors: Practice for 7-30 minutes, pushing through frustration while making mistakes. Stay focused on one aspect of the task.

• Reframe failure: Tell yourself, “These errors are wiring my brain for success!” to release dopamine.

• Keep it incremental: Break learning into small, manageable bouts rather than marathon sessions.

• Leverage high stakes: Connect your practice to a meaningful goal to boost motivation.

• Rest and repeat: Let changes solidify during sleep or naps, then revisit the task in 1-2 days.

Why This Matters Beyond the Gym

The beauty of this approach? It’s not just about physical skills. After a vestibular-charged, error-driven session, your brain stays primed for learning for at least an hour. Use that window to study, journal, or work on emotional goals—like processing a tough memory. The neurochemicals don’t care what you learn; they just make you better at learning anything.

Final Thoughts

Rewiring your nervous system is like upgrading your body’s operating system. By tapping into movement, balance, and the power of errors, you can unlock neuroplasticity to achieve your fitness goals and beyond. Embrace the frustration, seek novelty, and trust the process—your brain is built to adapt, no matter your age.
