Hi, my name is Stefan, I’m from Vienna and I like lifting, cooking, science and bears (you probably already figured this out). Most of my life I was an overweight nerd, who could not even think about physical exercise. Luckily this changed when I was 18 and I decided to lose weight (about 30kg). So I know exactly what it takes to switch to a healthier lifestyle. Yes, it isn’t easy, but I can help you achieve it!

Later I got into running, Crossfit, and through this into bodybuilding. This is when I met Menno Henselmans, did the Bayesian Bodybuilding Personal Trainer certification (major knowledge gains) “cum laude” and decided to work as an online coach specializing in body recomposition. Following this, I did the Intelligent Strength certification, perhaps the best personal training education there is out there. Recently, I also upgraded my nutrition knowledge by becoming an MNU certified nutritionist.

I’m here to help you to shift to a strong and healthy lifestlye. Don’t worry, there are no magic tricks or pills, and I don’t want to sell them to you. You will only get scientifically proven training concepts and tried and true nutrition advice: stuff, that actually works!

If you are interested how a healthy, delicious and nutritious diet can look like, check out my Instagram. Don’t hesitate to get in contact with me if you have any questions. If you are on Facebook, come by and say hello, I’d really appreciate it.


Hi, my name is Chantal, I’m an Italian girl who felt in love with the Viennese guy here on the left and his beautiful city. I love bodybuilding, Japanese culture and science too. I have a doctor in Biotechnology and for a long time I earned my money with research and teaching in the fields of biochemistry and molecular biology. I still love transmitting knowledge and I hope I can help you in your journey to a fitter you!

I’ve been training my whole life but never was particularly skilled at something. Around 2017, after trying different sports, I found bodybuilding being the most sustainable way to train for me. In 2019 I decided to learn more about coaching and did the Intelligent Strength Coach certification. Additionally, I invested a good bunch of time upgrading my nutrition knowledge together with Stefan. 2021 I stepped the first time on stage as a bikini competitor and made it 2nd in the bikini master division of the GNBF.

Together with Stefan, we run Beary Strong and want to help you reching your training and nutrition goals in a sustainable way. We work evidence and customer based: there are no magic pills and no cookie cutter programs. We will take time to find the best way which works for you!

My Instagram is a mixture of German and English: you fill wind recipes, training and nutrition topics and some stage pics 😉 Leave me a DM to ask me a question or just to say hello. I would really love hearing from you!
