End the Yo-Yo · with Craig Carden
The 21-Day Challenge
Losing weight was never your problem.
Keeping it off is.
Stop Starting Over.
Learn to Hold the Line.
Starts Wednesday 11 November 2026
Join the ChallengeThis isn't about losing weight. You've done that before — maybe many times. It's about what happens next: holding the line when the plan ends.
For 21 days you practise one thing — the daily behaviour that most affects whether your weight stays where you want it. Not motivation. A record of what you actually did.
Not what you intended to do. What you actually did.
Make the commitment — one clear thing, defined there and then.
Hold it and record it.
Read the evidence.
How it works
In the first session we turn it into one clear commitment you can check — a daily action that is either done or not done. No blank page and nothing to decide later: you leave session one knowing exactly what you're doing.
You hold it for 21 days — the one behaviour that keeps your weight where you want it, practised whether the motivation is there or not.
You check in each day. It takes under two minutes: did you do it, and if not, what happened just before.
You meet live four times, on Wednesday evenings, with me and the same group of up to 23 people.
On Day 22 you read your own record.
The four sessions
Each session is live, at 19:00 UK time, and runs for 75 minutes. The first part of each session, where I teach, is recorded for anyone who misses one. The group discussion is not recorded.
Success isn't perfection.
The challenge is to hold your commitment for 21 days. But if you miss, you haven't failed the challenge.
What you do next matters more than what you did yesterday. No restart. No penalty. No hiding the miss. You record it and continue.
At the end, you won't just have a feeling about how you did. You'll have a record: what you committed to, how often you held it, where you missed, what tended to happen before a miss, and what you did next.
Not a diet.
Not a meal plan.
Not therapy.
Not a promise you'll never regain.
Not 21 days to a new you.
Not 21 days to rewire your brain.
Just this: what happens when you make one clear commitment, record what actually happens, and refuse to turn a miss into quitting?- Four live sessions with me, 75 minutes each
- A group of no more than 23 people, the same people throughout
- One daily check-in that takes under two minutes
- A recording of the teaching part of every session
- Your own 21-day record, and the group's numbers read back each week
No motivational theatre. We look at what actually happened.
I'm Craig Carden — a former Royal Marines Commando, and a qualified personal trainer and sports therapist for around 25 years, though it was never my profession. I knew every diet and every training method. I've even sold weight-loss plans myself.
And I still spent two decades losing weight and putting it back on — while I watched person after person do exactly the same, the moment their plan ended. That's what taught me the real problem is never the plan. It's holding the line when the plan finishes.
In 2026 I stopped relying on motivation and started governing my days. For the first time, the weight stayed off. That's my own story — not a promise, and not a guarantee of what will happen for you. This challenge is where you start practising the same thing for yourself.
The challenge is complete in itself.
In January I run the first cohort of a separate 84-day programme, IMPACT 23 From Fate to Destiny™. Its founding price is £1,200. If you complete the challenge and decide you want to continue into that programme, your price is £597.
Completing means checking in on at least 15 of the 21 days. A recorded miss counts. If you don't continue, that's it. You keep your 21-day record and owe nothing.
Questions
What exactly will I be doing?
You commit to one clear, checkable daily behaviour — the one that most affects whether your weight stays where you want it. We make it concrete together in the first session, so you don't spend the challenge deciding. One thing, held for 21 days — something you can do, and check honestly, on the days you name in advance.
Is there anything I should not take on?
Choose a behaviour that is safe for you to change independently. If your chosen change involves alcohol or drug dependence, prescribed medication, restrictive eating, or something you're receiving medical or psychological treatment for, speak to the relevant healthcare professional before making changes. The 21-Day Challenge is not medical, nutritional or psychological treatment.
What if I miss a day?
You record it and continue. A miss is not a fail.
What if I can't make a session?
The teaching part of every session is recorded. Watch it before the next one. The group discussion is not recorded.
Who sees my check-in?
Your daily answers go into a private form. Sharing anything with the group is your choice. Results are only ever reported in anonymised form.
Do I need to know your books or IMPACT 23?
No. None of it is needed and none of it is taught here.
Can I get a refund?
A full refund on request up to the start of the first live session on 11 November. None after that.
You already know what holding the line would take.
