Kacper is 15. He trained at my former MMA club in Poland, Contender Kamienna Góra, and has won medals at MMA Polska, ALMMA and grappling competitions.

On August 7 he was attacked and stabbed several times in the neck. His heart stopped twice. He survived four surgeries and a stroke, and he is still fighting.

This week he started rehabilitation, his first attempts to stand with help from his therapists. A long road is ahead of him: neurological rehab, physiotherapy, speech therapy, medical equipment, and support for his mum, who stays by his side.

He used to fight on the mats. Now he’s fighting for his future. Let’s be his corner. 🙏

Building REVOON, we had to decide what role AI should play in a training app.

Here's where we landed: every number, every score and every training limit comes from fixed, tested rules. Same input, same answer, every time. The AI model helps with something it's genuinely good at: turning those facts into clear, readable messages.
It works only from the facts it's given, and every message is checked before anyone sees it. If a message doesn't pass the check, a simple pre-written one is shown instead.

Why this approach?

Picture an athlete asking their coach: "Why no sparring today? I feel fine."

We want the coach to be able to answer that in one clear sentence, and get the same answer for the same situation every time. Fixed rules make that possible. A recommendation is most useful when a human can explain it and stand behind it.

AI is a great voice. We keep the decisions with the rules and the coach.

We're still learning, and we'd love to hear how others are approaching this.

💧 Training’s done — but recovery hasn’t started until you rehydrate.

Most of us finish a session down 1–2% of body weight in sweat, and thirst alone won’t get you back to baseline. Here’s what a landmark review in the Journal of Applied Physiology says actually works:

1️⃣ Replace 150% of what you lost — about 1.5 L of fluid per kg of body weight lost
2️⃣ Sip it over a few hours instead of chugging — you’ll retain far more
3️⃣ Don’t rely on plain water — sodium is what helps you hold onto fluid
4️⃣ Carbs + protein boost retention — milk is one of the best-tested recovery drinks
5️⃣ Water + a real meal works too — food brings the electrolytes your drink is missing

🔖 Save this for your next hard session — and share it with the training partner who always forgets their bottle.

Conditioning day with João and MXA Sport. 🎥💪

Filming exercises can be just as much fun… and just as sweaty as the workout itself. 😄🔥

A few laughs, a few retakes, and plenty of good training.

Looks like ballet. Feels like your entire body is negotiating survival. 😅🩰

Rotational split squats develop stability, balance, core control, and resilient hips, knees, and ankles—all while challenging coordination.

Strong isn’t just heavy.
Strong is controlled.

Isometric Deadlift Hold – 30 kg 🔥

Hold the bar just off the floor until your legs start shaking… then stay there a little longer.

This is one of my favorite finishers for building a stronger deadlift, a rock-solid core, crushing grip strength, and a resilient posterior chain. Your glutes, hamstrings, spinal erectors, lats, core, and forearms are all working at maximum tension.

Sometimes the biggest gains come from holding the line, not adding more weight.

Wild heart. Sun-kissed soul. No permission needed. 🤎

Sometimes freedom looks like sunlight on your skin, dust under your boots, and the courage to be completely yourself.

I love the moments when something meaningful is just beginning.

Not because they’re loud or spectacular - but because they’re real.

Before the launch, before the test of reality, before the world sees what you’re building… there are people who choose to believe in your vision. Those moments are priceless.

REVOON is entering its final chapter before the official launch, and I couldn’t be more grateful for the people standing beside me on this journey.

Oumar and João - thank you for your trust, your support, and your willingness to help shape something bigger than a project. Your knowledge, humility, and values are exactly what REVOON is meant to represent.

This is a beautiful beginning. The last chapter before REVOON officially comes to life… 🔥🥋🚀

@mastwo - Very special “Thank you” for your words one day: “You have to believe in this!” 🫶

Congratulations, Mathias, on your well-deserved promotion to purple belt! 💜 Your consistency, humility, and dedication have made this achievement truly well deserved. Well done! The journey continues.

Thank you for every conversation, every exchange of ideas, and every thoughtful discussion. I truly appreciate your willingness to share your perspective—those moments are just as valuable as the time spent on the mats.

The mats have a way of bringing incredible people into our lives, and I’m truly grateful that our paths crossed.

Keep enjoying the journey—this is only the beginning of your next chapter… now in purple. 👊🥋💜

Here’s to sharing ideas, supporting one another, and enjoying the journey together. 💙

The biggest work happens where there are no spotlights.

Long before a project becomes visible, there are countless hours of learning, testing, failing, rebuilding, solving problems, and continuing when nobody is watching.

Over the past months, I’ve been quietly building. Step by step. One feature, one decision, one challenge at a time.

Today, the project is finally ready for the next phase: creating the visual content that will bring the vision to life.

And moments like this remind me of something important:

No one builds something meaningful alone.

Every great project is supported by people who believe in the vision, offer their time, share their knowledge, encourage you when things get difficult, and walk a part of the journey with you.

Every day, I feel grateful for the people who support, encourage, inspire, and help bring this vision to life: @maroucamara.levelup 🙏

This is only the beginning, but it is a milestone worth celebrating.

Small steps. Consistent effort. Shared vision.

That is how big things are built. 🙏✨
