The Voice in Your Head: Why Self-Talk Changes Outcomes
BLACK IRON RADIO EP. 371: The Voice in Your Head: Why Self-Talk Changes Outcomes
You hear your own voice more than anyone else's. Eventually it becomes the environment your brain lives in.
Amanda, Christin, and Jess Saxon get into how the story running in your head shapes your performance, your body image, your confidence, and your ability to build anything that lasts. They talk about why self-criticism gets mistaken for accountability, why the same event can produce two completely different conclusions depending on the narrator, and why the most elite athletes aren't relentlessly positive, they're just objective. They assess, adjust, and move on.
Plus the five-minute rule for processing a bad performance, why "fake it till you make it" is truer in performance than anywhere else, why food choices are data and not a character verdict, and how becoming a parent makes you hear your own inner voice completely differently.
You miss a workout. One person thinks, "I'm so lazy, I never stay consistent." Another thinks, "Life got busy, I'll get back to it tomorrow." Same event, completely different story, and that story is going to shape what happens next a lot more than the missed workout itself.
That's self-talk, and it's the ongoing internal dialogue that interprets everything that happens to you every day. Think of it as your internal narrator. Every workout, every meal, every glance in the mirror gets filtered through a story your brain creates about what it means. The problem is that your brain isn't wired for accuracy. Its job is survival, not truth-telling, so it defaults to a negative bias because catastrophizing kept our ancestors alive longer than optimism did.
Here's the part people miss: there is no shared, objective experience of your own life. Your experience is your interpretation of reality. The stories you repeat to yourself become your personal truth, even when they're not remotely accurate. And because of that negative bias, the pessimistic version of the story is always going to feel more believable than the generous one. Changing that takes a conscious decision, not a personality transplant.
Why It's Easier to Encourage Everyone Else But Yourself
Ask any coach and they'll tell you the same thing: cheering on a teammate, a client, or your own kid is easy. Cheering on yourself is somehow one of the hardest things to do, especially when there's a physical goal on the line.
Christin, who was days out from competing at the CrossFit Games when this podcast was recorded, described catching herself mid-interview recently, explaining that she needs to spend more time on weightlifting "because I'm not that strong." She stopped herself. She is strong. But if she keeps telling herself she isn't, that becomes what she perceives, and it caps her at whatever number she's decided represents her ceiling. When she started CrossFit ten years ago, she could snatch 75 pounds, and that was strong for her at the time. A decade later, she's a completely different athlete, with a completely different level of strength, but if she keeps repeating that old story, her brain has no reason to update the number.
A lot of athletes mistake self-criticism for accountability. It's easy to believe you have to be hard on yourself to get anywhere. And in small, short bursts, harsh self-talk can actually work. Telling yourself "don't be a bitch" right before you pick up a heavy barbell can produce a jolt of motivation. But that only works because it's occasional. Say it to yourself every single day and it loses its punch, and worse, it becomes chronic. Chronic self-criticism doesn't build toughness, it builds burnout, anxiety, and a fear of failing that makes it impossible to actually enjoy the process.
There's also a subtler cost: living in constant negative self-talk steals your ability to register wins as wins. You PR and think, "cool, what's next," while a mediocre day gets full emotional real estate. That's backwards. The grind, the mediocre days, the sessions where nothing clicks, those are just the baseline experience of training. The PRs are the payoff. They deserve to be treated like it.
Redirecting Instead of Just Suppressing the Negative
Jess, who's notorious for pressing out in her snatches during competition, used to spiral into "do not press out, do not press out" until she'd forget how to snatch entirely. The fix wasn't willing the negative thought away. It was finding a positive action to focus on instead, in her case, keeping the bar closer to her body earlier in the lift. Fix the cause with a positive instruction and the negative outcome takes care of itself.
This connects to something elite athletes actually do differently than the rest of us. It's not that they're relentlessly positive. It's that they're more objective. They evaluate without catastrophizing, they collect data, they assess and adjust, and then they move on. Arguably the single best predictor of long-term athletic success is whether someone has a short memory. Can you take the data, learn from it, and let it go, or does every setback turn into a permanent character indictment?
One sports psychologist put a number on this: the five-minute rule. After a performance, you get five minutes to reflect. Two of those minutes can be negative. The other three have to go toward celebrating what went right. Then you move on. That's it. Five minutes, not five hours of replaying the same missed lift in your head before bed.
How This Shows Up Everywhere, Not Just in Training
Self-talk doesn't stay contained to the gym. It touches body image, food choices, relationships, parenting, and your career, because it's really just your operating narrative about yourself.
Everyone has days where they don't love what they see in the mirror, and that's normal. The problem is when every photo or reflection becomes proof that you're not enough. A photo captures one moment. It doesn't capture your health, your strength, your personality, or your values. Treating a single image as the verdict on your entire worth is giving one screenshot way more authority than it's earned.
The same distortion happens with food. Nutrition and food choices are just data, but we turn them into judgments about our character. "I ate clean this week" or "I made really bad choices this week" implies a morality that food simply doesn't have. A better, more honest question is just: was that the best option you had available at the time? If yes, that's a win, and you move on. If not, that's useful information for next time, not evidence about who you are. Either way, one week of eating doesn't define you, and neither does your nutrition in general.
It also helps to remember that life isn't static. There are seasons where your capacity is high and seasons where you're just surviving. Jess is nearly two years postpartum and still describes herself as barely keeping her head above water between a daughter, a full-time job, a part-time job, and a podcast. But she's still working out five days a week. That's not failure. That's showing up inside a hard season, and that counts as a win even if it doesn't look like the highlight reel version of consistency.
Would You Say That to Your Mom?
Here's a gut check that cuts through a lot of the noise: would you ever say to someone you love what you just said to yourself?
If your mom told you she was going to start going to the gym three days a week and she only made it once, you wouldn't call her lazy or tell her to quit. You'd tell her one day is infinitely better than zero, and to keep going. You'd be encouraging without hesitation. That same grace has to apply internally. Your relationship with yourself deserves the same nurturing you'd give any external relationship, which means showing up for yourself even when you're imperfect, and extending yourself the same understanding you'd extend to literally anyone else in your life. There's no good reason your own standard should be all-or-nothing while everyone else gets to just be a flawed human.
That said, this isn't a call to live in forced positivity either. It's not realistic to feel like a rockstar 24/7, and pretending otherwise is its own kind of dishonesty. It's fine to have a day where a lift doesn't go well or you don't love how you look. The goal isn't eliminating those moments. It's not letting them become the constant, dominant voice. Dwell for five minutes, then look for something else in the session, or the day, that you can feel good about, and let that be the thing you carry forward.
Most of life actually lives in a gray, neutral zone anyway, not in the highs or the lows. That in-between space isn't a failure state. It's just what most days are. Body neutrality, as opposed to forced body positivity, applies the same idea: some days you're not going to feel amazing about how you look, and that's just a fact, not a crisis.
Shame Versus Guilt, and Why the Difference Matters
Shame rarely produces lasting change. Guilt, on the other hand, actually can, and the distinction between the two is worth sitting with.
Guilt says, "I did something that doesn't align with my values." Shame says, "There's something inherently wrong with me." Guilt says, "I skipped my workout today." Shame says, "I'm lazy." Guilt says, "I overate at dinner." Shame says, "I have no self-control." Guilt points at a behavior you can change. Shame points at your identity, and identities feel a lot harder to fix than behaviors do.
A lot of us grew up believing criticism was the thing that motivated us, that if we let up on ourselves even a little, we'd go soft. The research says the opposite. Feeling bad about yourself doesn't build sustainable habits. You might white-knuckle your way through a few days or weeks on self-punishment alone, but that motivation runs out because it was never built to last. Shame doesn't inspire action, it inspires hiding: skipping the gym because you're embarrassed, avoiding the scale, skipping check-ins with your coach, avoiding mirrors and photos, waiting for Monday or the new year to "really start."
What an Identity Shift Actually Means
This isn't about a Clark Kent style transformation into someone else entirely. An identity shift just means building a version of yourself that supports the change you're actually trying to make, whether that's around performance, nutrition, or anything else.
It's built on consistency, self-compassion, and a willingness to be a little uncomfortable without treating that discomfort as failure. For a lot of people, even saying something nice about themselves out loud feels uncomfortable at first. That's fine. Doing it anyway, consistently, is what shifts the identity over time.
Part of this is changing the questions you ask yourself after something goes wrong. Instead of "what's wrong with me," try: what happened here, what can I learn, why am I talking to myself this way, and what can I do differently tomorrow. Shit-talking yourself doesn't move you forward, it just leaves you in the same rut, and it creates the same kind of defensiveness in your relationship with yourself that it would in any relationship with another person.
A Practical Framework for Changing Your Self-Talk
Changing your internal dialogue is possible, but it takes time, repetition, and a willingness to actually notice and interrupt the pattern instead of running it on autopilot. Here's how that actually works in practice.
First, notice. Bring conscious attention to the recurring thought. Say it out loud if you can, that alone often defuses some of its power. Then ask: is this a fact, or is this a story? "I missed two workouts" is a fact. "I'm the laziest person in the world" is a story your brain built on top of that fact. Separating the two, and stripping out the emotion and judgment, is the whole game.
Second, watch your language. Absolute words like "always" and "never" are red flags, and so is language that reinforces a limiting belief you already hold, like "I'm a bad runner." Swap that for observational, temporary language: "today I noticed," "lately I've been." That kind of phrasing leaves room for change instead of locking you into a permanent verdict.
Third, actually rewrite the message. Take the story you were telling yourself and turn it into an open, factual statement instead. Speak to yourself the way the best coach you ever had would talk to you: challenging, but encouraging. Correcting, without humiliating. You can believe in yourself without shaming yourself first, and improvement doesn't require starting from a place of self-contempt.
Fourth, take action, because confidence is built on evidence, not affirmations. Your brain believes what you do more than what you say. Confirmation bias runs in both directions, and you can point it toward yourself by keeping small promises: get up when the alarm goes off, eat protein at every meal, finish the workout even if you have to modify it halfway through. Positive self-talk gets you started, but following through without judgment is what actually keeps the momentum going. If body image is where you're most stuck, you don't need to start there. Build the evidence somewhere else first and let neutral be the initial goal rather than glowing.
Real Habits You Can Start Using Today
Bookend your day. Set an intention each morning, something as simple as an "I will" statement, and then close the day by checking in against it. What went well, what didn't, what would you change tomorrow. This is a page straight out of the Five Minute Journal, and it earns its reputation because it takes about two minutes and creates real accountability.
After a hard training session, write down two things that went well, no matter how small. It could be as unrelated to the lift itself as "I drank enough water" or "I actually warmed up my shoulders today." There can be 99 things that went badly and it doesn't matter, you can always find two that went right.
Shift your attention from how your body looks to what it does. Pick one body part and notice, over the course of a day or week, what it's actually doing for you. You may not love how it looks right now, but it's still working, still carrying you through your life.
Take compliments without a disclaimer. If someone tells you that you look strong, or that your lift was impressive, resist the urge to add "well, I'm not that strong right now" or "I feel bloated today." Nobody compliments you as a lie. Say thank you, let yourself believe it, even a little, and move on.
Stop using unposed photos as evidence against yourself. Professional models get paid specifically because they understand angles, lighting, and posing, and that's not most of us. A photo taken mid-lift, mid-laugh, or mid-vacation while your husband snaps a thousand shots is not a referendum on how you look. It's one frame, not a verdict.
And if you're a parent in the thick of the postpartum phase, know that giving yourself positive self-talk when you're exhausted is genuinely harder, and that's fair to acknowledge. Bodies change after kids in ways that don't reverse, and that's okay. The more useful question isn't what your body looks like now versus before, it's what your body is capable of doing for the people who get to watch you do it.
Bottom Line
Improving your self-talk isn't about forcing constant positivity or pretending everything is fine when it isn't. It's about becoming more objectively accurate about yourself, separating fact from story, guilt from shame, and one bad photo or one missed workout from your actual worth. Stay curious, stay compassionate, and remember that confidence isn't the absence of failure, it's trusting that you'll respond well when failure shows up anyway. Every conversation you have with yourself is shaping the person you're becoming, so make sure that voice is one that's actually trying to help you grow.
