I have been attending Jonas Crossfit classes for a few months now and look forward to them every time. Jonas designs the courses very varied, effective and challenging and gives the participants valuable tips with his friendly and motivating manner. The main focus is on clean exercise, but also on making sure that each participant gets the most out of themselves. Through the courses with Jonas, I have found great pleasure in Crossfit and never thought that I would enjoy going to the gym so much. I can therefore highly recommend him as a trainer.
I participated in Jonas' intensive workshop on training and nutrition. We were taught the basics and shown what is important in achieving each goal. The workshop was professional and structured. Questions were answered directly and the context was conveyed in an understandable way. We got good tips for the implementation in everyday life.
I love training with Jonas! From my point of view the best trainer! He responds to my personal wishes and makes every training session varied. He has a very great know-how around the topic of sports & nutrition. My physical fitness has increased significantly since training with him! Thanks a lot
The training with Jonas is incredibly fun and has helped me to a completely new body feeling. As a psychologist, I was looking for a balance to my stressful everyday life and for a workout that would keep me fit and make me stronger. With Jonas I got the all-round package: A sympathetic and professional coach and training results that exceeded my expectations. With his positive and motivating manner, he has always helped me to get the best out of myself.
I can recommend the training with Jonas 100%!
I have found Jonas to be a very patient, competent and attentive trainer. After not doing any sports for a long time, he managed to motivate me to push my limits in training (jumping rope!!!) and have fun at the same time. Thank you Jonas. Clear recommendation!
I have trained with Jonas over a longer period of time and can only recommend his training (focus on strength training). He is incredibly motivating and responds appreciatively and individually to the circumstances.
The training with Jonas is varied and goal-oriented.
The focus of strength training is on clean movements, which I personally find very important.
My training was supplemented with nutritional coaching and a personalized workout plan, which rounded off my training perfectly.
I contacted Jonas to get back in shape specifically and with a sound training plan. Within 6 weeks, I was able to significantly increase my performance or strength and I felt much better in my skin. The subsequent body measurement confirmed the success in terms of fat burning and muscle building. The training was well structured and varied. The training sessions were easy to manage and fun. Jonas always has an open ear for questions about training, integrating rituals into everyday life, and optimizing nutrition. His explanations are easy to understand even for lay people. I can only recommend Jonas with his professional, friendly and empathetic manner.
Six weeks of intensive training, but with plan and progression have brought full success to all course participants. Jonas is not only extremely structured and reliable, but he is also a great motivator who has an incredible amount of fun at work. That's why every training session was really hard on the one hand, but in the end the laurels were won. I learned what I really need to pay attention to in terms of nutrition in connection with muscle building training and how to effectively design my training sessions in the future. Merci.
I know Jonas from various Crossfit courses and have recently completed a six-week functional coaching with him with the goal of reducing strength. Jonas emphasizes the correct execution of the exercises and explains them in an understandable way. The training structure was varied and challenging. Jonas is a super motivator who manages to make even the most strenuous workout fun. After the six weeks I have clearly built up strength and am motivated to continue with weight training. Jonas is a top trainer!
With Jonas as a trainer, you are exactly right. The professional introduction to the technique and his likeable way of motivating people to achieve top performance led to results that far exceeded my expectations. I could trust that he always set his requirements correctly, even against my own assessment, in order to get the best out of me. That is what makes the special push with this trainer. Results with a threefold increase in performance after only six weeks are the satisfying confirmation. I would never have thought that strength training could be so much fun.
My name is Tayyar, I am 44 and I work as an entrepreneur. I joined Jonas because I wanted to regain my former fitness after a Corona break. I also wanted a kick start for future CrossX classes. Specifically, I wanted to lose fat, build muscle and get fitter.
Before training with Jonas, I felt unmotivated and unfit. I really enjoyed the training with Jonas because he pushed me to my personal limits during the training sessions. I would never have trained so effectively and hard on my own. He motivated me very well and we had a lot of fun. Through his expertise and I felt in good hands. So I was able to focus on giving it my all. He knew how to motivate me.
Despite my personal hurdles like intense job, little time and little knowledge, I was able to make tremendous progress. I was able to achieve my set goals, such as building muscle, losing fat and increasing my fitness, within an intensive training program after a short period of time. I feel much fitter, stronger and above all motivated to continue training at the level I have reached.
Jonas was able to help me enormously with my goals through his knowledge, his interpersonal skills and also through a lot of humor. I am very grateful to Jonas for the progress I have made with him.
My name is Aleks, 38 years, from Cologne.
I did a 7 week Functional Coaching with Jonas with the goal to build up strength and to get new impulses for my training.
During the 7 weeks I noticed a significant increase in strength and was able to noticeably improve my performance. The training was varied and above all versatile. I felt challenged but not overwhelmed, and received a few really useful hacks to improve my posture/execution, for example, and thereby also increase my performance once again. Jonas listened to my individual needs and took time to address my concerns.
So I can definitely recommend Jonas, and hope to have the pleasure again soon!

Goal: Get fit, learn new exercises, exercise regularly
I have come a significant step closer to my goals through the training. I got to know many exercises and now I know how to train. The sessions were really fun and very professionally prepared and executed. The training times were very well adapted to my rhythm with family and job. I liked the exercises overall.
Jonas is a great guy who burns for the sport and was also able to motivate me well through his professionalism. I can definitely recommend the training.
I am very challenged in my professional life and have more output than input. Especially during the Corona Pandemic, I noticed that it was becoming increasingly difficult for me to motivate my employees. The PT with Jonas helped me to get back to my strength, performance and motivation. I am very athletic, but more at home in endurance and dance. The strength training with Jonas has shown me again possibilities to develop more strength, especially in the core. This helps me a lot in ballet! Through the joint training and a structured personal plan, I can also develop independently, which I find particularly good. Gladly again and again!
Started training with Jonas a good two years ago. Since then, Jonas has managed to keep me "on it" and keep my motivation high. Especially during the "Corona high time" the tips and plans for the training were extremely helpful. I always find the training very varied and effective. My goal of staying fit and getting better is thus getting closer every week. I can only recommend Jonas as a person and trainer!
Jonas has prepared me several times as a coach over longer periods for competitions in powerlifting.
During my training as a physiotherapist, I had little time to deal with an exact competition planning on the side. Therefore I was extremely happy that Jonas took over the planning completely and was very flexible to contact.
Especially his obsession with detail and the very individual planning, which was always customized during the preparation, fascinated me!
I can only recommend it and I will definitely book him again for my next competition.
I have been coaching with Jonas for a good year now (25). Besides my studies, weight training is an important hobby for me.
But in the last 5 years I stagnated a lot and hardly got stronger. Due to the well periodized training in the last months I could achieve progress in strength values as well as visually, which I would not have thought possible in such a short time. The optimized coordination of load and recovery has brought my strength values to a new level. Also, injuries that were a regular occurrence before have been absent since coaching with Jonas. He planned the sessions very professionally, in detail and above all individually for my goals. It is clear what extensive sports science knowledge Jonas brings as a personal trainer. He was also able to adapt the training to the Corona situation at short notice, so that progress was also made during this time.
With Jonas, you are at exactly the right address for effective and efficient training.
In what felt like my 10th attempt at doing fitness regularly, Jonas was a huge help to me. It quickly no longer felt like a compulsion to complete the exercises, but I really looked forward to our next session. I've been training with Jonas for over two years now, and he doesn't do a standard program, but responds individually to my physical and mental condition. I always feel very well taken care of with him. A very complete package: I've made visible progress, it's fun, and Jonas is also very flexible.
