Personal Coaching
Who is the coaching aimed at?
My coaching is aimed at you - ambitious hybrid athletes who are not involved in sport at a professional level, but are nevertheless extremely active and have an entrepreneurial background or are pursuing ambitions in this direction (e.g. intrapreneurs or managers). Online coaching enables you to receive support from any location. So it doesn't matter whether you live in Stuttgart, Heilbronn or Mannheim.
You have recognized the connection between sporting success, healthy eating, personal ambition, professional and personal success and financial independence. You know how difficult it is to combine a busy job with an active and healthy lifestyle. You strive to achieve perfection in all areas of your life and are prepared to work hard to achieve your goals.
My coaching offers you the support and strategies to bring sport, physical fitness, nutrition and personal and financial success into harmony and thus optimize your work-life.
It doesn't matter what sporting, professional, personal or financial goal you are pursuing. Be it a beach figure, preparation for a specific competition, general improvement of your fitness and health or optimization of your professional and financial situation. It is also not a knock-out criterion if we initially only focus on one area. To find out how we can work together, arrange a free initial consultation now. I look forward to getting to know you!

Success stories
from previous participants
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.

2019 begann ich mit CrossFit und lernte CoachK zunächst als Teilnehmer im Gruppentraining kennen. Seit 2021 trainiere ich in einer von ihm geleiteten Morgengruppe, die sich mittlerweile zu einer starken Gemeinschaft entwickelt hat. Seine Trainingsmethoden sind kreativ, fordern heraus und verbinden Krafttraining mit Kraftausdauer – immer mit dem Ziel, uns individuell zu fördern und zu fordern.
Durch seine Motivation habe ich mich 2023 erstmals einem Halbmarathon gestellt – etwas, das ich mir zuvor nicht zugetraut hätte. Begeistert vom Erfolg, folgte im nächsten Jahr die Vorbereitung auf einen Ironman. Konstantins unerschütterlicher Glaube an meine Fähigkeiten und seine Unterstützung haben mir geholfen, dieses große Ziel zu erreichen. Seine Worte „Solltest du das nicht schaffen, begleite ich dich so lange, bis du es tust“ gaben mir das nötige Vertrauen. Am Ende stand ich mit einer Finisher-Zeit von 13 Stunden im Ziel.
Was CoachK auszeichnet, ist nicht nur sein Wissen, sondern seine Fähigkeit, individuell auf jeden einzugehen – mit Humor, Empathie und Leidenschaft. Sein Training funktioniert, ist alltagstauglich und macht einfach Spaß – besonders für mich als Familienvater mit drei kleinen Kindern.
Abseits des Sports beeindruckt mich Konstantins Struktur, Disziplin und seine Fähigkeit, unglaublich viel in einem Tag zu schaffen. Gleichzeitig achtet er auf seine mentale Gesundheit und pflegt enge, bedeutsame Beziehungen. Als Freund, Trainer und Motivator ist er für mich eine absolute Bereicherung.
Kurz gesagt: Top Freund, top Trainer – 5 Sterne, gerne wieder!
Da es sich bei dieser Bewertung um eine Zusammenfassung handelt, habe ich hier die Langfassung.

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.

“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.

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!

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.

About me
Hi, I'm Konstantin Strassel,
Coach K,
your personal companion on the way to your best.
I support you in the areas of fitness, nutrition, work-life and finance. I was born in Stuttgart in 1993, completed a commercial apprenticeship, studied Communications Management (BAW) and obtained a Master's degree in Business Administration. My passion is aimed at like-minded people and similarly crazy people like myself - extreme athletes who dedicate their lives to sport without earning a living from it, and who at the same time want to advance professionally or develop themselves further.
I understand the challenges of balancing a time-consuming job with an active lifestyle. I recently successfully completed my first full Ironman in Frankfurt (long distance) after an intense preparation period combining up to 20-hour training weeks with 50-60 hour work weeks. In addition, I have already practiced several sports intensively, including martial arts (Ju-Jutsu), CrossFit, Hyrox, bodybuilding and triathlon. This experience helps me to support you effectively on your path.

On a professional level, I have been the managing partner of a medium-sized company in the advertising industry with over 25 employees since 2015. My life is mainly focused on this activity, which is also the center of my life. I have worked my way up from trainee to shareholder and work in sales, where I make a significant contribution to the annual turnover of over 4.5 million euros. So you see, this project is a matter of the heart for me and not a necessity to earn a living.
For this reason, the number of coaching places available is very limited.
My personal ambition and the experience of what my own body and mind are capable of are my main motivation for this work and my personal development. That is why I have been trying out many different sports since I was a child and am interested in how this changes the body. As a result, I have experienced many physical changes in myself over the years.
Professionally, I firmly believe that you can work for a good life and that hard work always pays off. I know from my own experience how hard it is to have a busy job and still be successful in sport. I currently combine around 60 hours in my main job with 15-20 hours of sporting activity a week.
I have always been hard-working and ambitious, and sport has always been my great love. Nevertheless, I also wanted to be successful in business and achieve financial stability. This experience and dedication enables me to support you in combining everything in life: sport, fitness, nutrition and work-life as well as personal financial success. As I love the outside perspective, I am also actively coached myself, as I know how important continuous learning and personal growth are.
I look forward to accompanying you on your journey and achieving your goals together. Let's tackle this challenge together!
Apps and Devices
In my location-independent online coaching, the use of specific apps, systems, trackers and devices is not absolutely necessary, but it is an advantage. What is important: I am open to all common apps, systems, trackers and devices and am already familiar with most of them. If I am not yet familiar with a particular app, I am open and willing to familiarize myself with it to ensure that we can achieve the best possible support and results for you.
In some cases, I will also recommend an app or two during the coaching session if you are not already using it to increase the results and professionalism. However, you must be aware that there may be additional costs involved.
Apps: Athlytic, Whoop, Strava, TrainingPeaks, MyFitnessPal, Apple Health und Fitness, Garmin Connect, Wahoo Element, AutoSleep uvm.

FAQ
My coaching stands out because of its exclusivity and personal dedication. I only take on a limited number of clients, as I do coaching out of passion and not out of financial necessity. This allows me to give each client the individual attention and support they deserve.
Since I don't see coaching as my main source of income, I take the liberty of making the introductory process relaxed and non-binding. I don't pressure anyone into making a decision, but focus on whether we are a good fit and whether I can really help you.
My passion for fitness, professional development, and financial planning flows into every collaboration. Although it is a hobby for me, I take the collaboration very seriously and am always committed to helping you succeed.
The coaching is suitable for ambitious hybrid athletes who train intensively and have a business background or are striving to achieve one. It is aimed at people who have recognized the connection between athletic success, professional and personal success, and financial independence, and who are willing to work hard to achieve their goals in fitness, nutrition, and career.
Yes, the coaching is 100% tailored to you. Every training and nutrition plan is specially adapted to your needs, goals, and current fitness level—regardless of whether you are just starting out or have already competed in your first competitions. In addition, you work directly with me. I personally accompany you through every phase of the coaching, from feedback discussions to ongoing support via WhatsApp and telephone. Your progress is my focus!
Our collaboration begins with a detailed, free initial consultation via Zoom, during which we discuss your previous experiences, goals, and current challenges. Based on this, we work together to develop your customized training and nutrition plan, which is available via the TrainingPeaks platform and can be downloaded directly to your smartwatch.
Every 14 days, we will have a feedback meeting in which we will discuss the coming weeks in detail and adapt the plan to any special circumstances in your work-life balance. If you have any questions during training, I am available via WhatsApp and telephone. Depending on the scope of the coaching, financial planning and career development strategies will also be discussed. This ensures that your training and all other areas of your life are optimally coordinated and that you make continuous progress.
Feedback takes place in approximately 14-day intervals via telephone or Zoom. These feedback sessions serve to discuss your progress, make adjustments, and ensure that you are on the right track. If you have any urgent questions, I am also available between feedback sessions via WhatsApp and telephone.
No, there is no communication limit. I usually respond quickly, within 24 hours during the week at the latest. On weekends, it may take a little longer.
Coaching costs €199 per month, with a minimum term of three months. A minimum term of three months is required because real progress and lasting change usually take time. It is more likely to achieve significant success during this period than in just four weeks. After the first three months, you can cancel at any time at the end of the current month.
In rare cases, I also offer individual consultations and fee-based advice. For this, I offer customized consultations and fees. Please note that I do not provide investment advice.
After the minimum term of 3 months, you can cancel the coaching at any time with one month's notice to the end of the month. There are no long-term commitments, so you remain flexible and can end the coaching when you feel it is right for you.
No problem! My coaching is flexible and customizable. If your focus is exclusively on athletic training, I will create customized training plans that are perfectly tailored to your goals and performance level. This way, you get exactly the support you need—without any obligations in other areas.
Please note: Even though the coaching is customized, the monthly fee remains the same. This allows me to guarantee that you receive the same high-quality support and assistance.
Yes, I also offer personal training sessions on site upon request. However right now only in Germany. This option falls under my fee-based consulting services, is agreed upon separately, and can be booked independently of the monthly flat rate. We will coordinate the exact conditions—such as location, scope, and remuneration—individually to ensure that the training is perfectly tailored to your goals.
Personal training sessions are usually booked occasionally as an add-on to monthly support. They are ideal for specific requirements such as optimizing exercise execution, running tests, or swimming training. These sessions can help you work specifically on your techniques and performance and offer additional value to continuous online support.
For most of my clients, however, coaching is location-independent and takes place online, offering maximum flexibility. If you would like on-site support, we will work together to find a suitable solution—tailored to your individual needs.
You can start at any time, provided there is a place available. Simply arrange a free initial consultation here to get started. If there are currently no places available, I can put you on the waiting list.
The number of coaching spots available is deliberately limited to ensure that I can offer each client the individual attention and support they deserve. By limiting the number of coaching spots, I can guarantee that each person receives personalized support and that I have sufficient time to address specific needs and challenges. My goal is to deliver high quality and sustainable results, which is only possible with a limited number of coaching spots.
I seek coaching for myself because I believe in the importance of continuous learning and personal growth. Even as a coach, there is always room for improvement and new perspectives. An outside perspective helps me to recognize my own blind spots and to continuously develop my skills. Through my own coaching experience, I can also better understand the challenges my clients face and how I can best support them. Ultimately, I want to always offer my clients the best, and that includes staying up to date and achieving my own goals.
