The number at your GP
Your HbA1c is in the range of 5.7 to 6.4 percent or just above. Nothing serious yet, you were told – but a direction you don't like.

HbA1c raised?
Take action now.
Your doctor says your long-term blood sugar is heading the wrong way. Maybe you are already taking metformin. That is not a verdict – it is your starting signal.
Twelve weeks of targeted training, a diet with fewer carbohydrates and support that sticks with you when everyday life gets in the way. So your body responds better to insulin again. Your treatment stays with your doctor.

Does this sound familiar?
Most people notice nothing for a long time. Then a value shows up in a lab report, and suddenly the topic is there. This is exactly the point where it pays to act – as early as possible.
Recently started on metformin
The tablet dose is set, the value is supposed to stabilise. And you wonder what you can contribute yourself instead of just waiting.
Belly, tiredness, cravings
Your waist gets wider, your energy drops after lunch, and in the evening you crave something sweet. That often has to do with blood sugar.
It's not your fault. But you're not powerless either.
A raised HbA1c usually means your cells respond less well to insulin. That insulin sensitivity can be trained – with four levers that are in your own hands.
Your muscles are your biggest sugar store
A large share of the sugar from food is taken up by your muscles. Building and using muscle creates room – that is why strength training is at the centre, not just going for walks.
Exercise opens the door even without much insulin
Working muscles pull sugar from the blood even when insulin is working less well. Regular endurance exercise and a short walk after meals strengthen this effect.
Fewer carbohydrates take the pressure off
Not banning, but reducing and distributing smartly: protein and vegetables first, carbohydrates where you actually need them. That keeps blood sugar spikes smaller.
Sleep and stress count too
Short nights and constant stress measurably worsen how insulin works. That is why they belong in the plan, not in a footnote.
General information, not medical advice. Diagnosis and treatment belong in the hands of doctors. Expert information on type 2 diabetes
Günter showed how it's done.
Type 2 diabetes, lots of medication, worries about his kidney values. Instead of talking about the stage, we stabilised his health first: more endurance, fewer carbohydrates, blood sugar always in view, medication supervised by his doctor.
Today, by his own account, Günter no longer needs blood sugar-lowering medication, his values are within the reference range – and at 63 he became world runner-up in bodybuilding.
Günter's journey is personal and can't be applied to everyone. It shows what is possible when you stick with it consistently.
Five steps across twelve weeks.
At the start your value at the doctor, at the end again. In between, the work – and you don't do it alone.
-
Initial consultation and your values
We talk about your lab results, medication, daily life and goal. You bring your current HbA1c and confirm with your doctor that training is right for you.
-
Your training and nutrition plan
Strength and endurance training at your pace, plus a diet with fewer carbohydrates – built from what you already like to eat.
-
Twelve weeks of training together
In Nuremberg once a week with me in person. Online with video feedback on your technique and a fixed weekly check-in.
-
Measure, understand, adjust
Blood sugar, waist circumference, weight and strength values go into the Camp Dörfl app. Every week we look at them and adjust whatever isn't working.

After twelve weeks: checking your HbA1c
You have the value checked by your doctor. We put start and finish side by side and plan how you keep what you have achieved.
What a diabetes coach does – and doesn't do.
As a diabetes coach I support you with training, nutrition and everyday life – in person in Nuremberg for Nuremberg, Fürth and Erlangen, or online across Germany. I am a personal trainer and coach, not a doctor and not a certified diabetes educator (Diabetesberater DDG). That is why training and medicine work side by side, not against each other.
What I do with you as your diabetes coach
Planning and supporting your training, adapting your diet to everyday life, recording your values, keeping you on track when life gets in the way.
What stays with your doctor
Diagnosis, lab values, medication and every decision on whether and when anything about your treatment changes. Nothing here is planned around that.
Two ways. The same care.
In person in Nuremberg or online from anywhere – plan, app and support are included in both.

Why it's a good investment
Your body needs this refresher again and again – like any system that is supposed to run reliably. Every hour you invest in yourself pays off in the years ahead.
Who the programme is meant for.
It fits if …
… your HbA1c is raised, type 2 diabetes is on the horizon or you are just starting on metformin – and you really want to change something over twelve weeks. You don't need any sports experience.
It does not fit if …
… you want to reduce medication without your doctor or are looking for a quick diet. For type 1 diabetes this programme is not the right setting.
What you want to know beforehand.
What does a diabetes coach do?
A diabetes coach helps you put into practice what makes the difference with prediabetes and type 2 diabetes: regular strength and endurance training, a diet with fewer carbohydrates, enough sleep and sticking with it for months. A coach makes no diagnosis and changes no medication – that stays with your doctor. At Camp Dörfl your coach is Dominik Dörfl: personal trainer, two-time German champion and the coach behind Günter Preis’ journey.
Is the diabetes coaching in Nuremberg also available online?
Yes. In person you train in Nuremberg – for people from Nuremberg, Fürth, Erlangen and the wider metropolitan region. Online, the coaching runs across Germany via the Camp Dörfl app with a weekly check-in and video feedback on your technique.
Who is the programme for?
For people with raised long-term blood sugar: an HbA1c in the prediabetes range between 5.7 and 6.4 percent, early type 2 diabetes or a recent start on metformin. What matters is the will to work at it consistently for twelve weeks.
I take metformin. Can I still take part?
Yes – especially then. The requirement is that your doctor knows about it and clears you for training. Nothing about your medication changes in the programme; that is decided solely by your doctor based on your values. If you take insulin or medication that can cause low blood sugar, we coordinate particularly closely with your doctor.
Will this lower my HbA1c?
Studies show that strength training, endurance exercise and a diet with fewer carbohydrates can improve insulin sensitivity and lower HbA1c. How strongly that works for you depends on your starting point and how you follow through. That is why no value is promised here – it is measured by your doctor before and after.
Do I have to give up carbohydrates completely?
No. Carbohydrates are reduced and spread sensibly across the day – not banned. The plan starts from what you already eat. Whatever you can't keep up doesn't go into the plan.
I haven't exercised in years. Is that a problem?
No. The start is based on what your body can handle. If you have had a long break, you begin with low volume and clean technique – that is exactly where most progress happens at the beginning.
How does the online option work?
You get your plan in the Camp Dörfl app, train at home or in the gym and send videos of your technique. Once a week there is a fixed check-in with feedback and adjustments. You enter your values in the app.
Do I need a glucose sensor?
No. A normal blood glucose meter is enough. If you use a sensor, you will see how you react to food and training especially clearly – that can be motivating, but it is optional.
What does the programme cost?
Twelve weeks in person in Nuremberg with weekly personal training cost €1,290, the online option €690. After that you can continue with the app or online coaching; the refresher every six months costs €249.
How do I sign up?
Via the contact form, by phone or on WhatsApp. In the initial consultation we clarify whether the programme suits you and which option makes sense.
First conversation
Every week you invest in yourself is well spent.
Write briefly where your values are right now and what's on your mind. You'll get a personal, honest assessment – even if the programme isn't the right fit at the moment.
