Performance Diagnostics 

INSCYD allows us to look “insight” the body of an athlete. Get to know the most important physiological metrics, as only elite trainers have been able to do so far – without having to invest heavily in expensive laboratory equipment.

​Key Metrices:

  • Maximum aerobic power – VO2max

  • Maximum glycolytic power – VLamax

  • Anaerobic threshold

  • Lactate accumulation rate at high intensity

  • Lactate recovery rate at low intensity

  • Fat & carbohydrate combustion rate

  • Aerobic vs. anaerobic energy contribution

​Key Functions:

  • Performance predictions

  • Strength and weakness profile

  • Individual performance tracking

  • Multi-athlete performance comparison

  • Highly individual training zones

Whether you are new to the sport, or you are an experienced athlete, you can benefit from such a test regardless of your ambitions or fitness level. Reach out to find out more about the different test options we offer.

With great commitment and flexibility, Selim has perfectly matched all training plans to my personal needs and schedule. Thanks to the bike training, I was able to improve my weakest discipline significantly. Selim being a top triathlete, his inputs and tips on nutrition and racing are invaluable. With the victory at 70.3 Mallorca in 2018, I was able to fulfill a dream and participate in the World Championship of Ironman 70.3 in South Africa in September 2018. This was a unique experience and, with the 12th final rank, a memory for eternity.

I have worked closely with Selim for a remarkable two-year journey that ultimately led to my podium finish at the World Championship in Hawaii. Throughout our partnership, Selim's expertise and guidance played a crucial role in developing my cycling skills, while his thoughtfully crafted plans ensured my overall well-being and motivation. Following a second-place finish at Ironman Frankfurt, I proudly secured third place in the prestigious race in Hawaii. This accomplishment stands as a testament to the precious support and great commitment that Selim provided every step of the way.

I started my journey to a more active lifestyle with Selim 5 years ago. He motivated and trained me from the couch to my first 5km race.  With his support and coaching I have since grown and participate in various half marathon races and a short triathlon.  Not only have I lost a decent amount of weight, but I have also gained strength, confidence and a zeal for life – Ready to face any challenge life throws my way!

A Life-Changing Journey:

I discovered endurance sports when I was 29 years old. I volunteered at an Ironman event, where I was amazed of the people racing. 

Since then, in 2009, I have completed over 100 triathlons (many of them podium finishes) completed various coaching courses, did studies in psychology, and turned into a full-time coach.

I have worked with athletes from Hawaii podium finishers to individuals picking up endurance sports for over ten years.

I am passionate about working closely with individuals to help and see them develop in their passion.

I firmly believe in a holistic approach that integrates physical, mental, and emotional well-being. That's why I focus on highly personalized experiences with my coaches...
