About Us
We Exist to Make Elite Training Knowledge Accessible to Everyone.
Real coaching. Real biomechanics. Real progressions. Built for the people who never had access to it.
About the Founder
Forged in the Gym. Not in a Boardroom.
Nethletic was built by František Och, founder and head of performance.
This isn't a tech founder who discovered fitness. It's 8 years of hands-on work. 500+ clients. Thousands of hours spent refining how to bridge clinical prehabilitation, pain relief, and peak athletic performance into one system that actually works.
Since early 2020, František has been systematically testing, refining, and validating every progression in this app. The goal was simple. Find the exact formula that takes an everyday person and trains their body toward an elite-level outcome. Safely. Repeatably.
Now it's live. But this is just Day One.
Why We Exist
Elite Training Protocols Shouldn't Be Locked Behind Professional Sport.
Walk into any gym and you'll see the same thing. People working hard. Getting nowhere. Risking injury. Wasting years. The knowledge that prevents this exists. Top athletes use it every day. It just never reached the people who needed it every day. That's what we're fixing.
What We Stand For
- Real coaching over algorithms. No AI hyper-personalization that gets mislead by self-diagnosis.
- Progressions over templates. Your program leads. Your body follows.
- Long-term results over quick fixes. Built for years, not for an Instagram cycle.
What We Stand Against
- Generic plans rebranded as personalized.
- Random workouts dressed up as training.
- Apps that match your habits instead of developing them.
What Methods We Use
The Same Science. Translated For You.
Nethletic programs are built on three pillars: biomechanics, structured progressions, and long-term periodization. None of this is theory. It is what the largest available datasets in sports science keep proving over and over.
Biomechanics
Every movement is chosen for a reason. The right exercise, in the right order, to develop the right capacity. Joint health, control, and strength built systematically.
Structured Progressions
Every workout is a calculated step up from the last. If a movement is too hard, you swap to a regression. Too easy, you progress up. You're never guessing where you are on the journey.
Long-Term Periodization
Real training isn't a 30-day challenge. It's planned across phases. Build phases. Strength phases. Recovery. We're building toward a system where every season of the year has a purpose.
The Research Behind the Method
Pain Is a Capacity Problem.
"It's your age, your desk job, just live with it." …while nothing truly changes. The real issue isn't a lack of willpower; it's a Capacity Problem.
Most people think back pain or sore tendons come from tight muscles. The instinct kicks in: stretch it out. But the data keeps showing the opposite.
Every tissue in your body — muscle, tendon, ligament — has a load limit. If you don't build that limit up, the tissue stays vulnerable. The stiffness people try to stretch away is usually not the cause. It's the symptom of a tissue compensating for missing capacity and your body trying to prevent injury.
Build the capacity. The symptom disappears.
fewer injuries with strength training.
The largest meta-analysis on injury prevention (Lauersen, Bertelsen and Andersen, 2014) pooled 25 randomized controlled trials covering 26,610 people. Strength training cut overall sports injuries by roughly 66%. Stretching alone showed no convincing preventive effect.
View studyfewer hamstring injuries. Fewer recurrent ones.
Petersen et al. (2011) ran a cluster-randomized trial with 942 footballers. Teams that added a single targeted strengthening exercise (the Nordic Hamstring) cut new hamstring injuries by 60% and recurrent injuries by 85%.
View studylower ACL reinjury risk.
Grindem et al. (2016) followed 106 athletes after ACL reconstruction. Those who met strict strength and symmetry criteria before returning to sport reinjured at 5.6%. Those who didn't reinjured at 38.2%. Targeted strength, control, and symmetry aren't finishing touches. They're the foundation.
View studypain reduction for chronic neck pain.
Andersen et al. (2008) randomized women with chronic neck pain into different training groups. The targeted strength training group saw worst-pain scores drop by 79% over 10 weeks. A larger follow-up (2012) across 447 office workers showed pain reductions in the 47% to 61% range across strength training variations.
View studyfewer injuries with the FIFA 11+.
Soligard et al. (2008), published in the BMJ, randomized 1,892 footballers across a full season. Teams using a structured warm-up built around strength, stability, and movement control saw overall injuries drop 32%. Overuse injuries dropped 53%. Severe injuries dropped 45%.
View studyThe Pattern Is Consistent.
Across hundreds of thousands of training hours and tens of thousands of subjects, the result is the same. Structured strength and progression beat stretching. Every time. By a lot.
The Bridge Analogy
Build the Margin. Life Stops Breaking You Down.
Engineers don't build a bridge to barely hold the cars that drive across it. They build it with several times the needed capacity. That margin is what keeps it safe.
Your body works the same way. The point of training isn't to prepare you for elite sport. It's to build enough reserve that 8 hours at a desk, lifting a heavy box, a weekend hike, or playing with your kids doesn't break you down.
We apply the same prehabilitation and biomechanics principles athletes use. Just scaled for regular life.

Why No AI Hyper-Personalization
Real Coaching Beats Algorithmic Guesswork.
Most modern fitness apps lean on AI personalization based on user input. Sounds smart. In practice, it's built on a broken foundation: self-diagnosis. The two are often opposites. An algorithm asking "what are your goals?" and "how do you feel?" just amplifies whatever bad pattern brought the person here in the first place.
Nethletic uses something different. Hand-built progressions tested across 500+ clients. The path isn't generated. It's known. Refined. Proven.
