Our professional team of coaches & sports scientists create a new and unique "Daily Workout" for every day. Each Daily Workout is only available on this, one calendar day. This is how we combine professional fitness planning with the maximum variety in exercises and prevent boredom.

The AI in our app customizes the Daily Workout before each training session based on your ability, equipment, and options: Before each workout, you can decide "live" which equipments you have available at the moment. Common equipment combinations are saved in equipment profiles (e.g. "at home", "gym"). Through feedback after each workout, our AI gets to know your fitness level better and better and adapts the Daily Workouts to your strengths and weaknesses.

Why does Kernwerk exist? What is our "Why"?

Fitness is not a protected term and anyone can call themselves a fitness trainer. That's why there is a lot of misinformation and bad trainers in the world. We love fitness with every muscle fiber of our body and see it as our mission to provide healthy, sustainable and evidence-based training worldwide and make it accessible to everyone.


Your fitness affects your health and your life. It doesn't matter if you work out once a week as a beginner or every day as a professional. If you get the right mental attitude regarding your training, your whole life will improve. And vice versa.


We believe there is no shortcut to true fitness. Fitness is work, and that's okay. Because working out can be fun. We are convinced that we can show every athlete the most interesting, motivating and effective way to achieve his or her personal fitness.


That's why our motivation is: fitness is real and fitness is honest. Don't look for shortcuts, let us help you get there faster.


Be fit. Feel fit.

How does the Kernwerk® app work?

Through the Kernwerk® app, we offer a worldwide unique combination of real trainers and intelligent AI, so that every trainee, at every fitness level and at every training location, can train with unlimited flexibility and maximum effectiveness, with or without equipment.


Two things make Kernwerk® special:


Our professional team of coaches & sports scientists create a new and unique "Daily Workout" for every day. Each Daily Workout is only available on this, one calendar day. This is how we combine professional fitness planning with the maximum variety in exercises and prevent boredom.


The AI in our app customizes the Daily Workout before each training session based on your ability, equipment, and options: Before each workout, you can decide "live" which equipments you have available at the moment. Common equipment combinations are saved in equipment profiles (e.g. "at home", "gym"). Through feedback after each workout, our AI gets to know your fitness level better and better and adapts the Daily Workouts to your strengths and weaknesses.


We pick up everyone where they are at: Whether you're a beginner, advanced or competitive athlete. You tell us how many times a week you can train, and we'll create the perfect workout for you every day. It doesn't matter on which days you train. We take care that every training session offers the optimum for you and that you achieve the maximum training effect.


Through the Daily Workout principle, all users in our community train together on every training day - even though everyone trains at their own level. We motivate each other, we train on our own terms and together we get a little bit better every day. No excuses. No limits. #trainLimitless
