  • Reach Your Full Potential – Athletic Development

    Becoming a better athlete (& human) needs work and direction. This is easier said than done while we face adversity and knowledge gaps. With the following series of blog posts I will introduce you to my coaching framework that is based on first principle thinking and doing the basics right. The goal is to help you to reach your full potential no matter where you are in your athletic development.

    Why first principle thinking?

    Breaking down problems to the smallest known core truth will help you to build up knowledge and apply this to your very personal situation. 

    Here is an example: “I want to run a faster 5k“. Good! Let’s break this down. What is needed to move your body faster from A to B? You need to put one foot in front of the other. Duh! How do we know what the best way of doing this is tho (good running technique)? Well thanks to physics (& years of experience of humans running fast) we will find a solution. So before we do anything else we have to look at the movement pattern of your running technique and figure out if that foundation is set up right or if you are trying to build a huge house (good fitness) on a shaky foundation (bad technique). For example this might lead us to look into gait analysis and how the force from the impact of running will travel through your body. Once we are past the point of getting into a great running technique (that will make you less prone to injuries) we can move up the thought chain again and go to the next bigger problem: worrying about how to structure your training. To do that we need to figure out what your other limiting factors are to run a faster 5k. Do we need more oxygen intake or more efficient muscles? What kind of work (training, nutrition, mental, time management etc) do we need to put in to get past these limiting factors? And then we build up your program from there. 

    This approach might feel overwhelming at first but it will set you up for LONGTERM success. As we go along you will get a hang of it and it will make a lot of sense. Let’s take a look at our topics:

    Reach Your Full Potential Series: 

    1. Goal Setting – Understand Your Why
    2. Know Your Limits – Testing & Planning
    3. Adaptation In The Body  – Cardiovascular, Metabolic, Muscular, Bones & Hormones
    4. Training Zones
    5. Trainings Load & Stress Management 
    6. Intensity – How Much & How Hard
    7. Recovery – Sleep & Stress
    8. Nutrition –  Fuel The Work & Energy Demands 
    9. Mind Games & Longterm Planning 
    10. Winning By Making Less Mistakes
    11. Putting It All Together 

    There is a lot of ground to cover and the personal rate of learning will fluctuate. To make it easier I will try to paint a vivid picture by using examples along the way. As my background is in cycling and triathlon these examples will often be from those sports but the cool thing about first principle thinking: you will understand how you can relate this to your sport & situation.

    To reach our full potential as an athlete and human we need to work hard and learn from our mistakes. While trying to manage a social, work and family this can be a lot. So show yourself some compassion along the way and keep up the grind.

  • Performance Analyzer

    Performance Analyzer

    Athletes love data. We measure power, heart rate, lactate, VO2max, and whatever else our gadgets can throw at us. But often, getting proper performance testing means paying for expensive lab sessions or investing in subscription-based tools that lock insights behind a paywall.

    That never sat well with me. So, as a small personal project, I spent a few days coding a free performance analyzer that anyone can use. No subscriptions, no hidden fees—just a straightforward tool that helps athletes understand their fitness levels using established physiological protocols.

    How It Works

    The analyzer is built around two test days, designed to measure VO2max, VLamax, and metabolic efficiency. These tests follow well-documented methods, providing meaningful insights without requiring a trip to a lab.

    Test Day 1: The 30-Second Step Test

    A classic incremental ramp test, where power increases by 25 watts every 30 seconds until exhaustion. This method effectively estimates VO2max, offering a solid picture of aerobic capacity. It’s efficient, straightforward, and works well.

    Test Day 2: Time Trials & Sprint Test

    On the second day, we refine the data with:

    • three-minute and six-minute time trial to improve VO2max accuracy.
    • short sprint test to assess glycolytic power and metabolic balance.

    These results are then combined to give a well-rounded view of an athlete’s current performance level.

    What You Get

    The analyzer provides key performance metrics, including:

    • VO2max – Your maximal oxygen uptake, a crucial endurance marker.
    • VLamax – A measure of glycolytic (anaerobic) power, which influences endurance efficiency.
    • Metabolic Profile – Insights into energy system utilization for better training decisions.

    Easy Access: Free Files for Garmin, Zwift, and TrainingPeaks

    To make the process as seamless as possible, I’ve created:

    • Garmin files for structured execution.
    • Zwift files for virtual testing.
    • A free TrainingPeaks plan to guide you through each step.

    For Runners, Too

    Cyclists aren’t the only ones who like data. The same approach applies to running, with a tailored protocol for runners who want to measure their VO2max and metabolic efficiency—all available for free.

    A Small Project, But Hopefully a Useful One

    I built this because I enjoy projects like these, and because I believe that some things in sport should simply be free. Making a ton of money off athletes by putting basic physiological testing behind paywalls never really felt right to me. So, if this tool can help even a few athletes get useful insights without having to pay for yet another subscription, then it’s worth it.

    Everything is available on the homepage, and I’m happy to answer any questions. Enjoy the testing, and may your VO2max be high and your VLamax precisely where you want it.
