The coaching plan that adapts to your day — not the other way around. Workouts, nutrition and an AI that walks with you through the day. No gym, no crash diet. 60 days, one clear goal.
60-hour week, a sick kid, a meeting in Munich — and the plan is gone again. Most coaching apps build a program that only works when life stands still. getStark is built for the opposite.
getStark is a coaching system that thinks with you: your training plan, your nutrition and an AI companion that knows your day — so you don't have to decide what's due today. The system handles that. Your job: do it.
For 8 years I've been training people whose lives are too full, too irregular or too tired for the gym. Mothers, freelancers, commuters, shift-working parents. getStark is the program I built with them — in living rooms and parks. Not in studios. Not in a vacuum.
What you get from me: a plan that fits your reality. An AI that reminds you when I'm asleep. And me, when you have questions an AI can't answer.
Like a friend who happens to be a personal trainer.
How my coachees describe me:
One app that connects training and nutrition — with an AI that knows your day. Built and tested with 400+ coachees who did not want to rearrange their lives just to train.
120+ workouts between 7 and 45 minutes. Bodyweight, mobility, cardio. Living room, park, hotel — wherever you are.
Recipes with 4 ingredients and 15 minutes of kitchen time. No powders, no Sunday meal-prep, no banned-food list.
When Kristina sleeps, the AI is awake. It knows your day, your sleep and your energy level — and adjusts today's training accordingly.
The program builds up. No overwhelm at the start, no boredom at the end. You feel it in your body — and in your calendar.
You learn the movements, find your rhythm, build the first routines. Day 7: more morning energy. Day 14: better sleep.
The workouts get harder, nutrition and mindset interlock. Weeks 4–5: first visible physical change.
More strength, more energy, a clearly shifted body sense. The last weeks lock in what you built — and you notice: it sticks.
Get the fitness nation app. 60-second onboarding: goal, level, available time, injuries.
No trainer-scroll, no marketplace tiles. Tell the app where you stand — Kristina has already written the program for it. Start right away.
The AI reminds you, adjusts, celebrates small wins. I show up personally in the weekly check-ins. You train.
The AI accompanies you in your daily life with short check-ins, reminders, and concrete suggestions. It tracks your progress, celebrates your milestones with you, and helps you stay focused – even on stressful days.
Your workouts aren't generic; they evolve with you. And getStark doesn't end after your workout: the AI also guides you through your daily routines – small, clear steps that are easy to integrate into your day. Whether it's activation minutes in the morning, quick mobility snacks during the day, or your evening check-out: these routines ensure that your body gets something back from you every day.
Nutrition at getStark isn't a constraint. AI supports you with tailored recommendations based on your goals, activity levels, and preferences – so food empowers you instead of stressing you out. No dieting feeling. No restrictions. Just a lifestyle that works long-term.
The truth is: perseverance is the game-changer. This is precisely where getStark provides the strongest support – with motivation, series tracking, and gentle nudges when your energy is running low. This way, you not only achieve quick results – but results that last.
The getStark AI is not a ChatGPT bot answering every question from scratch. It knows your training history, your level, your injuries and your day. It turns that into a proposal you accept or reject in one tap.
Example dialog. Real conversations stay with you.
After my second child I couldn't find anything that fit in 30 minutes. In week 4 I had a plan I trusted for the first time in years. In week 8 I was on the yoga mat in the morning before the house woke up — voluntarily.
Three years away from the gym. With getStark I start before my first email. My back is calm for the first time in years.
After 6 weeks I did my first two pull-ups. At a park bar, no studio. I cried.
You've started a hundred times — and never pulled through. This time, a coach starts with you.
You need no gym experience. Bodyweight is enough. Your living room is enough.
You want to get stronger — without grinding through complicated plans.
You want a person who sees you — and an AI that reminds you during the day. Both. No either/or.
You want to train at home. Morning, evening, in-between — when it fits you.
