Fitness for Every Body
The Great Lock In Has Started. Are You Already Behind?
Forget waiting until January. Millions are using the last 4 months of 2025 to completely transform their lives. From September 1st to December 31st, it's time to lock in, level up, and enter 2026 as someone unrecognizable. The question is: are you in?
The Movement That's Taking Over TikTok (And Your Life)
121 Days. No Excuses. Total Transformation.
The Great Lock In isn't just another fitness challenge. It's a complete life overhaul that's exploded across social media, with over 500 million TikTok views and climbing.
The concept is simple: From September 1st to December 31st, you "lock in" on your goals with laser focus. No more "I'll start Monday." No more "New Year, New Me." You start NOW and arrive at 2026 already transformed.
Why Everyone's Obsessed
"October is the new January" has become the rallying cry. While everyone else is sliding into holiday mode, eating poorly, skipping workouts, and waiting for January's motivation that never comes - you're getting ahead.
Research from University College London shows it takes an average of 66 days to form a habit. The Great Lock In gives you 121 days - almost double what you need. By the time everyone else is making resolutions, yours are already automatic.
The Rules (Or Lack Thereof)
Unlike rigid challenges like 75 Hard, The Great Lock In is beautifully flexible:
- You make your own rules based on YOUR goals
- No perfection required - it's about consistency, not streaks
- All areas of life welcome - fitness, finance, relationships, career
- Community-driven - millions doing it together
Most people are focusing on 3-5 key areas: daily movement, better nutrition, consistent sleep, financial discipline, and skill development. But your Lock In is YOURS to design.
Why September Hits Different Than January
The Psychology of Fall Transformation
January starts with a hangover. Literally and figuratively. You're broke from the holidays, exhausted from parties, guilty from overeating, and forced into resolutions by social pressure.
September starts with energy. Kids are back in school. Work is ramping up. The weather's perfect. You have natural momentum from the "back to school" mindset that's hardwired from years of education.
The Strategic Advantage
Less Competition, More Results
- Gyms are empty (not packed like January)
- Healthy food is cheaper (not marked up for "resolution season")
- You get trainer attention (they're not overwhelmed)
- Habits stick better (less social pressure, more personal motivation)
The Holiday Shield Effect
Start habits now, and by the time holiday temptations arrive, you've got 60+ days of momentum. Studies show people with established exercise routines navigate holidays 73% better than those who start in January.
The Mathematics of Success
Traditional January Start:
- January 1: Make resolution
- January 19: Most people quit (yes, there's actually a "Quitter's Day")
- Total habit-building days: 19
Great Lock In Start:
- September 1: Begin transformation
- December 31: 121 days of practice
- January 1: You're already the person others want to become

- Better sleep comes naturally
- Nutrition choices improve automatically
- Mental clarity enhances learning
- Energy increases for side hustles
- Confidence builds for all goals
That's where Motion comes in. While you can track finances in a spreadsheet and learning in a journal, you need something that makes fitness accountability automatic, adaptive, and actually fun.

How Motion Makes Your Lock In Actually Stick
The Problem with Most Lock In Attempts
Week 1: Fire and motivation. Hitting every goal.
Week 3: Life happens. Miss a day. Feel guilty.
Week 5: "I already failed. I'll try again next year."
Sound familiar? The problem isn't you - it's trying to be perfect instead of consistent.
Motion's Lock In Superpowers
Adaptive Goals That Get It Your goals automatically adjust to your life. Busy week at work? Goals scale down. Feeling strong? They scale up. No guilt, no falling behind, just consistent progress.
Weekly Battles for Lock In Accountability Compete with other Lock In participants based on effort percentage, not fitness level. A beginner at 110% beats an athlete at 90%. Fair, motivating, addictive.
Your Motmot Keeps You Locked In Miss a day? Your virtual pet gets sad but doesn't die. It's about consistency, not perfection. Plus, who can resist those eyes asking for a walk?
Track EVERYTHING That Counts Gym session? Counts. Yoga? Counts. Dancing while cleaning? Counts. Walk to clear your head? Counts. Motion values movement, not just "workouts."
Lock In Community Built In Connect with thousands of others doing the Lock In. Share wins, get support on tough days, find accountability partners. You're not alone in this.

Your Lock In Starts Now (Yes, Whenever you're Reading This!)
"But I Missed September 1st..."
Stop. This perfectionist thinking is exactly what The Great Lock In rebels against.
- Starting September 15th? You still get 107 days.
- Starting October 1st? That's the Winter Arc - still 90 days!
- Starting today? You're ahead of everyone waiting for January.
The best time to start was September 1st. The second best time is RIGHT NOW.
Your First 48 Hours Lock In Plan
Hour 1: Choose Your Focus Pick 3-5 areas maximum. Fitness should be one (it cascades into everything else).
Hour 2: Set Your Non-Negotiables Not goals - commitments. "I will move for 20 minutes daily" not "I will run 5 miles daily."
Day 1: Start Stupidly Small 10-minute walk. 5 push-ups. One healthy meal. Build momentum, not muscle (yet).
Day 2: Track and Celebrate Log everything in Motion. Your Motmot celebrates. You're officially locked in.
The Lock In Levels
Soft Lock In: 3-4 commitments, flexibility built in, focus on consistency
Standard Lock In: 5-6 commitments, some strict rules, balanced approach
Hard Lock In: 7+ commitments, non-negotiable rules, total transformation
Start soft. You can always level up. You can't always recover from burning out.
Frequently asked questions
If you have anything else you want to ask, reach out to us.
Is it too late to start The Great Lock In?
Never! While it officially runs September 1 - December 31, starting any day still gives you massive transformation time. Mid-September? You still get months. October? Join the Winter Arc version. The point is starting now, not waiting for perfect timing.
How is this different from 75 Hard?
The Great Lock In is flexible and self-directed - you choose your rules. 75 Hard has strict, non-negotiable rules everyone follows. Lock In is 121 days of consistency; 75 Hard is 75 days of perfection. Both work, but Lock In is more sustainable for most people.
What if I miss a day during my Lock In?
Keep going! The Lock In is about consistency, not perfection. Motion's adaptive goals and weekly averages mean one bad day doesn't ruin anything. This isn't about never missing; it's about never giving up.
Can I just focus on fitness for my Lock In?
Absolutely! Many people choose one area to transform. Fitness is actually the most popular choice because it cascades into other improvements - better sleep, more energy, increased confidence. Motion's perfect for a fitness-focused Lock In.
How do I track non-fitness Lock In goals?
Motion handles your fitness tracking brilliantly. For other goals, many Lock In participants use: Notion for habit tracking, Mint for financial goals, Duolingo for languages, or simple journal apps. The key is picking tools you'll actually use daily.
What's the success rate for the Lock In?
While there's no official data, TikTok evidence suggests 60-70% of participants maintain at least half their habits through the full period. Compare that to New Year's resolutions with an 8% success rate. The community support and flexible approach make a huge difference.
Should I announce my Lock In publicly?
Research shows public accountability increases success by 65%. But choose your comfort level. Share with close friends, join Motion's community, or post on TikTok with #TheGreatLockIn. The key is some form of accountability, not necessarily full publicity.
What happens after December 31st?
That's the beauty - by then, your Lock In habits ARE your lifestyle. Most participants report keeping 70-80% of their changes because they've had 4 months to make them automatic. January 1st isn't a start date anymore; it's a celebration of who you've become.
