Milton Keynes · Kiln Farm studio
For over-40s who are tired of diets that never stick. We help you understand what is blocking progress — then coach you week by week until the weight stays off.
See the real reasons why you are burning fat — or not — at our Kiln Farm studio for £79.
This is a 2-minute non-invasive test (see photos and video below) followed by a plain-English review — 30 minutes in total. You leave with a plan of what is blocking progress — not another guess from the bathroom scales.
Numbers you almost never get from home scales or a normal gym scan — explained in plain English on the day.
Inflammation and HPA-axis readings are much more accurate than a typical gym scan or home scales. Individual results vary.
Watch what happens in your £79 Body MOT at our Kiln Farm studio.
After your Body MOT we walk through your numbers in plain English — fat, muscle, bone, and stress indicators. If coaching is a fit, we invite you onto a programme built for healthy body recomposition — you decide when you are ready.
We then storyboard what you need to eat and how you should exercise from those results. Your plan is bespoke to you and age-appropriate for over-40s — not a generic template or a PDF meal plan you will abandon by February. Your £129/month coaching programme is where we put that storyboard into practice each week.
On the £129/month programme we also test your metabolism with indirect calorimetry — unlike typical gyms. Clinical nutrition experts advise it as the most reliable way to measure energy needs and set food targets, which helps avoid under- or over-eating for weight loss. That shows whether your metabolism is slow and exactly what to do about it — measured burn rate, not a calculator guess.
Track real change, not just the scales
We test your metabolism with indirect calorimetry — unlike typical gyms — so you know if it is slow and what to do

Going to the gym twice a week is useful — but it only covers a few hours. Fat loss and body recomposition are decided by what you eat, how much you move, and how you train across the whole week. Daily accountability — logging food, steps, and exercise in the app — means we see patterns early, adjust your plan before you stall, and keep you honest on the days you are not in the studio. That is why clients who check in every day usually get much better results than people who only train twice a week with no eyes on the rest of their week.

Why us
Scales, trainers, and diet apps each solve a slice — and they usually cost you more money, more time, or both before you get a real answer.
Everyone else
Scales guess weight. Trainers eyeball you. Apps only count calories.
Months of trial-and-error — more time and money on the wrong plan
With us
Professional Body MOT — fat, muscle, bone, stress indicators, and clear next steps
Everyone else
Same morning guess. Generic meal PDFs. “Eat less” on a loop.
Another programme fee, another restart — usually slower and more expensive
With us
A storyboarded food & training plan matched to your scan and lifestyle
Everyone else
Nothing between PT sessions. App nudges with no human coach.
Gym-twice-a-week or PT blocks often cost more hours and cash — with big gaps between sessions
With us
3 small-group studio sessions a week plus daily food, steps, and exercise logging in the app
Everyone else
Home scales miss muscle and hidden fat. Diet apps ignore metabolic health.
Waiting until health slips usually costs more time — and far more money — later
With us
Built for over-40s — recomposition that protects muscle and energy
Next step
Almost everyone starts with the Body MOT. Pick what comes after — or if App Pro / PT is a better fit.

Hi, I'm Darren
I was a stressed-out senior software test manager in London who couldn't get into shape. After a health scare I rebuilt my life — Great Britain Age Group Triathlete, health coach, and the person who built Automate My Fitness because I was tired of guessing.
After coaching hundreds of people I realised diets weren't failing — the plans were. So I built what I wished I'd had: Body MOT testing, food and training logging, and a coach who actually looks at your data.
I still enjoy weekends away. I still have the occasional beer with friends. I don't believe in perfect health — I believe in understanding your body well enough to enjoy life.
