Coach K

In Konstantin, I have not only found a coach but also a wonderful person. He is always available, whether by phone or WhatsApp, and responds to every question or last-minute request regarding the training plan. Among other things, he has helped me to pay more attention to my fat intake and to greatly improve my VO2 max and my overall performance in the gym. Konstantin has also always been there for me when it comes to my finances. You can talk to him about anything, no matter what the topic. I am overjoyed to have such a good coach by my side.

I have been interested in physical fitness, health, and well-being for years. For a long time, I trained on my own and struggled to achieve the goals I had set for myself. I often experienced pain, and my motivation to train kept waning. When I met Coach K, we hit it off right away.  I could immediately identify with his open manner and positive attitude to life, and we trained together during the coronavirus lockdowns and contact restrictions. This allowed me to enjoy intensive support, and his encouragement and pushing drove me to my limits. Under his guidance and motivation, I was able to expand my skill set and learn double unders, for example. My technique in Olympic weightlifting has also improved significantly. As an ambitious amateur athlete, I was thrilled to see my strength values in powerlifting steadily improve, despite my advanced age of over 35. At the same time, my body fat percentage decreased and I feel as fit as I did in my twenties. As a major project, I wanted to complete a marathon on my 40th birthday in addition to my strength training. Since I have struggled with knee pain my entire life and don't enjoy running, this was a real challenge for me. Thanks to the customized strength training plan, I was able to complete the eight-month running preparation without injury or pain, maintain my strength levels, and actually finish a marathon one week after my 40th birthday. I am very proud of this achievement and very grateful to Coach K. 
His positive attitude inspires me again and again, and I have been physically active several times a week for years.

I weigh 104 kilograms and my goal is to successfully complete the middle distance. I have already completed several sprint distances, and my training up to now has been unstructured and overwhelming. Thanks to the training plan tailored to my individual needs, I can achieve my clearly defined goals week after week and look back with pride on what I have achieved. Konstantin has taken my training to the next level, and I can only recommend it to everyone.

“Coach K has taken my training to the next level.”

I have been training regularly for many years—despite high professional demands in management and frequent travel. But it was only through working with Konstantin 2025 that my training gained the structure and systematic approach necessary to achieve truly measurable progress.

His approach is well thought out, efficient, and precisely tailored to my time constraints and physical condition. It's not a rigid plan, but an intelligent system that responds flexibly to stress and everyday life – without losing any of its effectiveness.

When I compare my performance data from 2018 and 2025, I see clear progress, especially in VO₂max, running economy, and overall resilience. I now train more specifically, recover better, and get more out of every session - even with a full schedule.

I started CrossFit in 2019 and first got to know CoachK as a participant in group training. Since 2021, I have been training in a morning group led by him, which has since developed into a strong community. His training methods are creative, challenging, and combine strength training with strength endurance—always with the goal of promoting and challenging us individually.

Thanks to his motivation, I ran my first half marathon in 2023 – something I would never have believed myself capable of before. Inspired by my success, I started preparing for an Ironman the following year. Konstantin's unwavering belief in my abilities and his support helped me achieve this major goal. His words, “If you don't make it, I'll accompany you until you do,” gave me the confidence I needed. In the end, I crossed the finish line with a time of 13 hours.

What sets CoachK apart is not only his knowledge, but his ability to respond to each individual with humor, empathy, and passion. His training works, is suitable for everyday use, and is simply fun—especially for me as a family man with three small children.

Outside of sports, I am impressed by Konstantin's structure, discipline, and his ability to accomplish an incredible amount in a single day. At the same time, he pays attention to his mental health and cultivates close, meaningful relationships. As a friend, coach, and motivator, he is an absolute asset to me.

In short: top friend, top coach – 5 stars, I'd gladly do it again!

In December 2021, I started my first CrossFit sessions in Konstantin's 6AM group, which I can only say positive things about—a great group and a fantastic coach! Despite the early hour, he always manages to spread good cheer and provide great motivation. During every workout, he challenges you to push beyond your limits and develop skills you never knew you had.

What sets Konstantin apart is his ability to respond to each person individually. Even when I had to switch to shift work due to a move and a job change, we always found a suitable solution for my training together. Even during periods when I didn't do CrossFit for a while, he was always there to support me and help me get back in shape - Konstantin always has a helpful answer. His support and motivation are simply unbeatable!
