There’s a moment most of us know well. You were doing so well. Training was consistent, momentum was building, and then—life happens. A busy season, kids, sickness, injury. A bad week that turned into a bad month. And suddenly you’re standing at the starting line again, looking at everything you think you’ve lost, wondering if you even have it in you to begin again.
Here’s what I want to share with you from 17 years of studying the science of human performance: starting over isn’t a setback. It’s a skill—and it helps you grow.
What Resilience Actually Is
We’ve romanticized resilience into something it’s not. We picture it as mental toughness: gritting your teeth, never backing down, bouncing back like nothing touched you. But that’s not what the research recommends—and it’s not realistic to keep pushing through no matter what. The science of resilience, studied in positive psychology for three decades, tells a very different story.
Resilience isn’t the absence of struggle; it’s the capacity to move through struggle and grow from it. Psychologists call this post-traumatic growth—the phenomenon where people don’t just return to their baseline after difficulty but actually surpass it. The disruption becomes the doorway. And as much as it can feel heart-wrenchingly difficult to move through loss or rebuild after divorce or a health challenge, when you remember that better days are possible—and you’re not getting an old version of you back but are building something better—the future begins to feel more hopeful.
I lost three of my best friends to suicide, and it prompted me to write a book about how to keep going on the hard days. Instead of doom and gloom, it became the most joy-filled project I’ve ever worked on. This is because positive psychology gives you the tools to boost your positivity and protect your mental health. I’d walk for hours on the phone with my team, activating positive emotions through movement and nature, sharing awe-inspiring stories of real people who found reasons to live—and are experiencing amazing futures as a result.
In fitness, we already understand post-traumatic growth in the body. Think about it: you don’t build muscle by staying comfortable. You create micro-tears, recover, and come back stronger. Resilience works exactly the same way: the setback is the stimulus, and the restart is the rep.
“Resilience isn’t the absence of struggle; it’s the capacity to move through struggle and grow from it.”
Why Starting Over Feels So Hard
If resilience is so natural, why does starting over feel so brutal? Because of the fresh start fallacy, the belief that a restart erases everything that came before. It’s the meaning we create around the setback and your comeback that makes the difference.
When you return to the gym after a break, your nervous system remembers. When you pick up a dropped habit, your brain hasn’t forgotten the neural pathways you built. Muscle memory is real, identity formed through past behavior is persistent, and your body and brain are far more primed after a pause than you give them credit for.
The gap between who you were and where you are right now is not as wide as it feels. In reality, starting from scratch is almost always starting from experience. But our minds don’t lead with that data. Instead, the inner critic shows up, tallying every missed workout, every abandoned plan, every promise you made to yourself. That voice isn’t telling the truth, though. It’s telling a story, and you get to decide whether you keep reading it.
The Neuroscience of the Comeback
Here’s what happens in your brain when you decide to start again: your prefrontal cortex, the portion responsible for planning, identity, and intentional behavior, gets activated. Instead of running on autopilot, you’re making a conscious choice, and that’s one of the most psychologically powerful things a human being can do.
Research on self-regulation shows that recommitting—even after multiple stops and starts—strengthens the neural circuitry that makes future commitment easier. Every time you actively choose to begin again, you’re literally wiring yourself to be that kind of person.
In 2024, I slipped in the bathroom and broke my arm, which meant no proper workouts for weeks. That frustration gave me profound gratitude for my body and the privilege of being able to move. It motivated me to sign up for my first marathon, start training 10 weeks after the fracture, and run a sub-four-hour race just 12 weeks later. If I hadn’t fallen, I doubt I’d have taken action on something I’d been intending for so long. The challenge was actually a gift.
There’s also the role of self-compassion, which shows that treating yourself with the kindness you’d offer a good friend is a performance enhancer. People who practice self-compassion after setbacks return to their goals faster, with more consistency, and with significantly less anxiety than those who self-criticize. It turns out that beating yourself up for the break doesn’t motivate you, it only slows you down.
The Identity Shift
Positive psychology talks about identity-based behavior change, built on the simple but profound idea that lasting change doesn’t come from what you do but from who you decide you are.
When someone asks if you’re a runner and you haven’t run in six months, you might say no. But what if you said, “I’m someone who runs, I just haven’t recently.” That subtle shift from behavior to identity changes how you approach the restart. You’re not someone who used to be consistent—you’re someone returning to consistency. You’re not someone who failed but someone discovering what it takes to sustain it. When you lead with identity instead of performance outcomes, the comeback stops being about catching up and starts being about continuing. That’s an entirely different psychological experience, and it produces entirely different results.
You Were Never as Far Behind as You Thought
Starting over is not a detour from the journey—it is the journey. Every strong woman who has ever built something—a body, a baby, a business, a life—has had to find her way back more than once.
Resilience isn’t what you have when nothing goes wrong. It’s what you discover when everything does—and you choose, again and again, to grow. That’s where the real strength lives.
Practical Tools for Starting Over Strong
Resilience is trainable. Here’s how to build it, starting today:
Run a compassionate debrief
Pause and acknowledge what you’ve moved through—not to analyze or shame yourself, but to understand. What felt challenging? What can you learn from it? How can you grow because of it?
Lower the bar—on purpose
The biggest mistake people make when restarting is trying to return at the same level as when they left. Your nervous system needs to rebuild trust, and your psychology needs a series of wins to rebuild momentum. Start smaller than feels necessary, then build.
Reconnect to your why
Not the goal on the whiteboard—the feeling underneath it. Why does this matter? What does your health make possible in the rest of your life? Meaning is one of the most powerful drivers of sustained behavior change.
Celebrate the return, not just the result
Before you track the weights, the pace, or the progress, acknowledge that you showed up. The return itself is the win.
