Testimonials
Sophie Molinard
Superhuman 2021
I reached out to Seiza Training because I often suffered from pain in my knees and back while running long distance. Since one of my all time goals is to run a marathon, this problem had to be solved.
The coaching process started with discussing my goals and needs. After this coaching call a coaching plan was made based upon my specific needs. Every exercise in my schedule was explained by a video of the coaches showing the exercise, which was very handy since I didn’t know any fitness exercises.
The program showed me the importance of overall strength and mobility: I can now run 30 kilometers without any physical complaints and feel more prepared than ever to run a marathon. Not only did my body get stronger which made running long distance a lot easier, I also got faster. I can now quite easily run at a pace of 4:40min/km on short distance, something I never thought was possible.
What I especially like about Seiza Training is the personal approach. Tom and Nick are both super friendly and help you with everything you need, they correct where necessary but most importantly they celebrate all your victories with you, big and small. They really want to see you succeed, which is very encouraging!

Two years ago I started working out without any experience, but not much later I got a back injury.
To be honest, at the time I thought I would never be able to achieve my goals, that my body was not made for it. Through contact with the club physio however, I ended up with Tom.
For months I followed physiotherapy and my back improved. Even more important was the confidence I gained by learning to pay attention to form, tempo, etc. I got back into fitness and started with online coaching with Seiza Training. Meanwhile, I am about four months into it and I feel better and better.
The fact that I can go to Tom and Nick with any questions at any time is a huge comfort. Don’t forget that they are both very good and motivated professionals.
Moreover, all the exercises are geared towards my goals I want to achieve. I couldn’t be happier with my choice!

The journey is the destination:
• Rehab ➡️ Movement Patterns
• Mvmt ➡️ Strength Training
• Strength Training ➡️ Owning the Compounds
• Compounds ➡️ Gymnastics
• Gymnastics ➡️ Functional Strength for his Boxing
Jonas did it all while staying healthy throughout the process. We gladly interrupt whatever we’re doing to help him out.
