My Exercise Journey

I’ve always been an active person. As a child, I started with football and swimming. However, when I reached middle school, balancing both sports with academics became too much, and my grades began to suffer. I had to make a choice, and I went with football because most of my friends were on the team. I played for several more years before transitioning to a different form of fitness.

Discovering the Gym:

In 2016 or 2017, I started going to the gym, completely clueless about what to do. I turned to YouTube and Google to learn how to improve my body and build strength. Back then, I drew a lot of inspiration from fitness creators like Mike Thurston, Maxx Chewning, and Christian Guzman.

I still remember my early days in the gym, trying to perfect my “super cool I have a great pump and sick workout” photo. The above picture was taken in 2018.

This was also taken in 2018. The angle is just very nice so it’s looking like I’m the “BIG & STRONG” guy. It even became my profile picture on social media for a long time. (Yes, I wanted to look cool! LOL.)
By 2019, I had reached the strongest point in my fitness journey. In the above video you see my casually leg press 260 KG. Unfortunately, I don’t have any photos or videos from 2020 and 2021 because I decluttered my phone and Google Photos (oops!).
In 2022, I made progress but didn’t obsess over capturing those “super cool I have a great pump and sick workout” pictures. By 2023, I was fully focused on staying consistent and building a solid foundation for the years to come.

2024: A Game-Changing Year

This year, everything changed. I remained consistent with my gym routine while reducing my body fat percentage to nearly 5%. I felt and look better than ever.

The very nice 2024 “super cool I have a great pump and sick workout” picture!
This is my 2024 “super cool I have a back tattoo and it looks super sick” picture!

But the biggest shift in 2024 came when I added Muay Thai to my fitness routine.

Muay Thai: A New Beginning

Muay Thai completely transformed my approach to fitness. Over three months of intense training, I developed strength, endurance, and discipline like never before. It was both physically and mentally challenging, but it taught me the value of embracing discomfort and pushing through the grind. My personal goal during this time was not just to learn Muay Thai but also to overcome a mental hurdle: keeping my eyes open and staying composed when getting punched in the face.

Discovering the Need for Flexibility

As much as I loved Muay Thai, it highlighted a weakness: my flexibility. My kicks weren’t as high or fluid as I wanted them to be. This realization led me to incorporate yoga into my routine while training in Thailand.

I started following a video series by Yoga with Kassandra and made it part of my daily practice. The results have been incredible—my kicks are higher, my movements are more fluid, and I feel stronger and more balanced overall.

A Shift to Calisthenics

Another change in my exercise journey is incorporating calisthenics workouts at home. I’m focusing on mastering bodyweight movements to make my fitness more functional and adaptable. With van life in mind for 2025, I aim to reduce reliance on gym access and embrace a flexible, home-based routine.

TOTAL TIME: 89 MIN ~ 1.5 HOUR.

For my workout I use the Boxing Timer they also used in the gym in Thailand. I have set a few presets to set it up exactly how I want.

  • For the warm up run I now make it very flexible by following the Nike Running Club Plan = Marathon (18 Weeks in total). This means that I have different workouts everyday, sometimes also rest days to train for my marathon. So on those days I’m going to skip the run and do the warming up preset.
  • The Warming Up Preset = 3 rounds 5 MIN + Warning at 30 Seconds + Rest 30 Seconds. Total min: 16:03 (the 3 seconds are the prepare time before timer starts)
  • Workout Preset = 24 rounds 1 MIN + Warning at 10 Seconds + Rest 15 Seconds to switch exercise + try to rest. Total min: 29:48 (also with 3 seconds prepare time before timer starts)
  • Cooldown Preset = 1 round 10 MIN + Warning at 30 Seconds. Total min: 10:03 (also with 3 seconds prepare time before timer starts)

I also now use the Boxing Timer as my pomodoro timer, a great productivity hack haha! I like this boxing timer because it’s also comes with a “Workout DJ”. So when you select your Apple Music Playlist it’s going to start and stop playing while doing the timer. During my pomodoro breaks I like to do handstands, a little bit of stretching or shadow boxing. Just to move my body throughout the day because most of the time I’m sitting in front of my laptop working.

Embracing New Challenges

Muay Thai didn’t just improve my strength and flexibility—it boosted my stamina and mental toughness. After months of consistent training, including rope skipping and running on the island, I began craving greater challenges.

For 2025, I’ve set my sights on running a marathon and tackling even more physical milestones. These challenges aren’t just about fitness; they’re opportunities to expand my comfort zone, grow mentally, and prove what’s possible with commitment.

2024 has been about building a strong foundation. Now, 2025 is the year to take things to the next level—physically, mentally, and beyond. This journey isn’t just about exercise; it’s about becoming the best version of myself, one workout, one challenge, and one step at a time.

Update: On Sunday 8 December, 2024 I have registered myself for my first ever Marathon on 13 April 2025. I’m already very exited and use The Nike Running Club for my training plan.

My First Marathon – Doné Hieltjes Style

The Game Plan

Marathon Enschede, The Netherlands: 13 April 2025

It’s in dutch, but it’s basically saying: You are in!

Aiming for: Time 4 Hours and 30 minutes: I don’t know if that’s fast or slow, but this is what I read on the internet! In your first marathon it’s doesn’t matter what time you have, as long as you finish the Marathon, that is my first goal for my first marathon.

  1. Conservative but Achievable: This time goal provides a buffer for unexpected challenges, such as fatigue or hitting the infamous “wall” around the 30 km mark. It allows you to adapt without feeling pressured.
  2. Focus on Completion: For a first marathon, finishing strong is more important than chasing an ambitious time. A goal like 4:30 keeps you relaxed and focused on pacing yourself wisely.
  3. Steady Start: With a target pace of approximately 6:20 per kilometer, you can conserve energy early in the race, ensuring you have reserves for the latter stages.

What Does This Mean in Practice?

  • My Kilometer Pace: Aim for a consistent pace of 6:20 – 6:25 per kilometer throughout the race.
  • Halfway Checkpoint: Pass the halfway mark (21.1 km) in roughly 2 hours and 10 minutes, which aligns perfectly with your overall goal.

Alternative Strategy: Divide the Race into Phases

Breaking the marathon into manageable segments can help maintain focus and optimize performance:

  • First 10 km: Start conservatively at 6:25 per kilometer to ease into the race and avoid burning out early.
  • Kilometer 10-30: Maintain a steady pace of 6:20-6:25 per kilometer, prioritizing consistent effort and energy conservation.
  • Kilometer 30-42: Follow how your body feels—if you have energy left, pick up the pace. Otherwise, concentrate on maintaining rhythm and finishing strong.

Final Advice by my assistant, business partner, adviser: Chat GPT! haha

The key to a successful first marathon is staying calm, enjoying the experience, and learning from it. 

Treat it as a building block for future runs rather than a definitive performance metric. 

With the right pacing and mindset, you’ll not only complete your marathon but also create a memorable and rewarding journey.

Good luck, and go crush it! 🏃‍♂️✨

Especially when I see in the Plan that I need to do a 32,2 KM practice run. SHEEEESH!

Update: December 15, 2024 – Running My First Marathon – Doné Hieltjes Style

My Spontaneous Marathon Experience

Sometimes, life throws you spontaneous challenges. On Sunday, December 15, 2024, I set out for what was supposed to be a simple 10-kilometer training run. But as I started running, I felt amazing—strong, motivated, and full of energy. That’s when the wild idea hit me: why not just run a full marathon today?

The goal wasn’t about time or preparation—it was about testing my limits and finding my “wall” both physically and mentally. Was this a reckless idea? Absolutely! But after my time in Thailand, my conditioning had never been better, so I thought, Why not? With my favorite music blasting in my ears, I decided to give it a shot.

No Preparation, No Problem?

Since this was supposed to be just 10 kilometers (17 weeks out training plan), I hadn’t brought any water, gels, or fuel—nothing. So my first objective was clear: find water. Luckily, in the Netherlands, train stations often have water refill points. I set my sights on the nearest station and kept running.

By the time I reached the station and rehydrated, I still felt fantastic. I decided to push forward and make my way to the next town. That’s when I hit the half-marathon mark. But the temperature was dropping, and I was burning through calories fast. I started feeling cold and realized I desperately needed fuel to keep going.

The Aldi Lifesaver

While running, I searched for the nearest supermarket and found an Aldi about 2.8 kilometers away. Driven by hunger and the craving for sugar, I powered through until I reached it around the 22–23 kilometer mark. Aldi became my savior that day. I bought:

  • 1 orange juice
  • 1 smoothie
  • 1 Coca-Cola
  • 2 Snickers
  • 2 Haribo candy bars
  • 1 Twix

The total came to €10.51—a small price to pay for the fuel I needed to keep going. Outside the store, I downed a candy bar, a Snickers, the orange juice, and the Coke. Slowly, I started to feel alive again and prepared myself to finish what I’d started.

The Final Stretch

The next few kilometers were brutal. My body was freezing, and it took until around the 24–27 kilometer mark for warmth to return to my muscles. By then, my legs began to give out occasionally, but mentally, I felt strong. To keep moving, I adopted a new rhythm: 1 minute of walking, 4 minutes of running.

At kilometer 30, I decided to turn everything off—no music, no Nike Running Club updates (yes, I’d set it to announce my pace and time every minute). I wanted to face myself, to confront any mental battles. Surprisingly, there were no demons to fight. Mentally, I felt great; the only issue was that my legs weren’t cooperating with my mental energy. Does this mean I hit “the wall”? I’m still not sure.

At kilometer 39, I saw an opportunity: I could finish the marathon within 4 hours and 30 minutes—the same goal I’ve set for my first official marathon on April 13, 2025. With a new burst of energy, I pushed harder and harder, determined to beat that time.

And I did it.

I finished my first-ever spontaneous marathon in 4:27:08. BOOOOOM.

Half-marathon time: 1:56:40

You can see al the other stats below, and a proud Doné Hieltjes who finished his first ever marathon:

Reflecting on the Experience

This wasn’t a conventional marathon by any means, but it was my marathon. Running spontaneously, unprepared, and fueled by candy and sheer determination, I learned so much about my physical and mental resilience. Was it the smartest decision? Probably not. But the experience of pushing through the unknown made it one of the most rewarding days of my life.

There’s so much more to come—this is just the beginning. Let’s keep pushing, growing, and smashing limits. 🔥

Let’s go champs!
