If you’ve scrolled social media lately, you’ve probably seen it:
Checklists. Whiteboards. Timed walks. No alcohol. No sugar. No missed workouts. No excuses.
Welcome to the latest wellness wave: The Great Lock-In.
Part wellness challenge, part self-improvement bootcamp, the “lock-in” is being hailed as the cold-weather version of 75 Hard: a strict, high-discipline, everything-at-once push toward becoming your most optimized self.
The idea? For a set number of weeks (usually 4 to 8), you lock yourself into a routine with near-zero flexibility. Think:
- 10,000 steps a day
- One workout (or two)
- Cold showers
- Clean eating only
- No alcohol
- Reading 10 pages a day
- Sleep by 10
- No missed days. No days off. No “life happens” clause.
It’s pitched as a way to escape chaos, regain control, and prove to yourself that you can “do hard things.”
But there’s a difference between doing something hard and doing something unsustainably rigid.
Let’s break it down.
Why This Trend Is So Appealing
There’s no doubt about it: the lock-in movement taps into something powerful.
It offers structure in a world full of noise.
It gives you clear rules when motivation is low.
And it promises momentum—the feeling of being in control, on fire, and “finally doing the things I said I’d do.”
In a season where people feel sluggish, distracted, or mentally scattered, the idea of going all-in feels... refreshing. Even empowering.
And for many people, these challenges do kickstart action. They get you back in the game. They rebuild confidence. They reconnect you to discipline and intention.
That’s not nothing.
But here’s the catch: rigidity works—until life shows up.
When “All In” Becomes “All or Nothing”
The biggest flaw in ultra-restrictive challenges like this isn’t that they’re too hard.
It’s that they don’t allow for life.
Miss one day, and you’ve “failed.”
Slip up once, and the whole thing crumbles.
You’re either locked in or locked out—there’s no middle ground.
And that mindset doesn’t build resilience.
It builds shame, guilt, and burnout disguised as willpower.
Study after study in behavior change and health psychology confirms:
Rigid control often leads to rebound behavior.
The stricter the rules, the harder the backlash when you inevitably break them.
Even the original 75 Hard creator admits: this isn’t meant to be sustainable. It’s a test. But when social media spins it as a long-term solution to real-life problems, people start expecting permanent results from temporary restriction.
That’s not discipline.
That’s behavior volatility in a motivational disguise.
So What Should You Do Instead?
If you’re feeling pulled toward a Lock-In-style routine, good. That means your desire to level up is strong. That’s a win.
But you don’t need to overhaul your life to build momentum.
You just need to consistently improve the foundations.
Start here:
1. Pick 3 core habits—not 9.
Instead of changing everything overnight, choose 3 high-leverage behaviors:
- Daily walk
- Strength training 3x/week
- Consistent bedtime
Do them consistently. Give yourself room to win.
2. Add structure, not restriction.
You don’t need food rules. You need food rhythms.
You don’t need a no-mistake mindset. You need a bounce-back strategy.
Structure supports success. Rigidity crushes it.
3. Build identity, not intensity.
The goal isn’t just to hit 10,000 steps or drink your gallon of water.
The goal is to become someone who takes care of their body—even on off days.
Even when you’re tired. Even when life is chaotic.
That doesn’t happen by locking yourself into a 6-week sprint.
It happens by staying in the game longer than anyone else.
Final Thought
There’s nothing wrong with having seasons of intensity.
Sometimes a reset is exactly what you need.
But don’t confuse a short-term discipline sprint with long-term health.
And don’t measure your worth by how long you can say “no” to everything.
Sustainability doesn’t mean softness.
It means staying consistent long enough for it to change your life.
So if you’re looking to lock in…
Lock into your next right habit—not a challenge you’ll abandon by the first snowstorm.
