About
It’s not Gear you’re Missing ...
... It’s someone who’s taken the hits, learned the hard way — and knows the way out.
Arnold 1999
I'm Arnold, your personal strength & healthspan mechanic. I've spent the last two and a half decades figuring out what doesn’t work — so now, we can focus on what does.
- In-person or video — worldwide
- Tailored sessions that fit
- No fluff. Just results.
Warning: This service isn’t cheap. That’s because I don’t sell hours. I sell direction. The only thing that expires is your time — don’t waste it.
The Principle
No Muscles - No Health!
It's that simple.
But strength training alone won't save you from modern life systematically destroying your biology.
We're running Paleolithic hardware in a Neolithic world
Everything from chronic stress and artificial light to sedentary lifestyles and processed food is shortening your healthspan.
Stress kills ...
... hormone production and drives cravings for garbage.
Poor sleep prevents recovery. Sitting combined with poor diet destroys insulin sensitivity no matter how hard you train.
Synthetic Sweat
Isn't just about lifting heavy
It's about recalibrating every pillar
Movement, sleep, stress management, and real food your body actually recognizes. Strength is the foundation, but longevity demands the full stack.
I'll teach you to build a body that lasts
Not through motivation, but through systems that align with your biology instead of fighting it.

A NOTE ON WEIGHT LOSS
I'm not a weight loss coach — and that's intentional. If you’re looking to chase short-term numbers on a scale, I’m not your guy.
This work is about integrity, sustainability, and a deeper connection between mind and body. We're optimizing for healthspan, not vanity metrics.
Else if you're dealing with severe obesity there are foundational issues that need addressing first — metabolic, hormonal, psychological. Start by reading this:
