Owen’s own Challenge 31

I didn’t just build this.
I did it.

Owen built this website, then did his own Challenge 31 in the app from day one. Every number below is from that log, day by day.

−4.5kg82.4kg → 77.9kg
52workouts completed
15,056steps a day, on average

I run the company behind this site, so I did the challenge myself before sending anyone else to it. Every day weighed in, every meal tracked, every session I could make. The app did the thinking, I did the work.

“While the financial reward is wonderful, the greatest gift has been how I feel now — healthier, stronger, and more confident — and the pride my husband, my sons, and my extended family have shown.”

A plan that adjusts weekly

Your calories, macros and focus update with your results. The plan bends before you break.

People who keep you going

The cohort chat is where most members get through the hard weeks. Someone is always on the same day as you.

Before you join

Straight answers.

About the code, which plan to pick, time, equipment, judging and renewals.

How do I use code OWEN?

Pick a plan below and tap its button. At checkout, enter OWEN in the promo code box and 10% comes off before you pay — £149.99 becomes £134.99 for a challenge entry, £24.99 becomes £22.49 a month for membership.

Challenge or membership — which should I pick?

Pick the challenge if you want a fixed start date, a finish line, the £18,000 prize fund and the money-back guarantee — it's one payment for eight weeks. Pick membership if you want the app as your everyday training and food tracker without a deadline; you can add a challenge entry whenever one opens.

I've started things like this before and quit.

Most people have. That's why the challenge has a fixed start date, a fixed end date and thousands of other people running the same eight weeks alongside you. The accountability isn't willpower — it's structure, weekly check-ins and a deadline that doesn't move.

I don't have a gym membership.

You choose home or gym when you join and the programme is built around whatever equipment you actually have. Plenty of winners have trained entirely at home.

I don't have two hours a day.

Sessions run 45–60 minutes. The plan is designed around real schedules — work, kids, shift patterns. If you can find four hours a week you can do this.

How are the prize winners chosen?

Winners are chosen by judging the transformation achieved from each entrant's own starting point — a judged competition based on your transformation, not a prize draw or game of chance. You are not competing against people with a different starting body. Full criteria are in the competition terms.

Does anything renew automatically?

A challenge entry is a one-off £149.99 — it never renews. Membership bills £24.99 monthly until you cancel, which you can do in the app at any time. Unlimited is £299.99 a year paid in full, or 3 monthly payments of £116.67 (£349.99 in total), and renews yearly until you cancel. We state this here rather than surprising you at checkout.

Is this suitable if I have a medical condition?

Speak to your doctor before starting this or any weight-loss or exercise programme, particularly if you have an existing medical condition, are pregnant or breastfeeding, or are taking medication. We are not able to give medical advice and the programme is not a substitute for it.

Your before photo can start today.

Eight weeks from now you'll have proof, not just a feeling, and a routine you're still running long after. Next challenge starts 26 October.
