Zydrunas'
Program,
Now in an App.
The 4-time World's Strongest Man's adaptive training system. Built from 20 years of competition. An engine that adapts to you, session after session.
Most Athletes
Are Training Wrong.
The research is clear. Static programs don't adapt. And adaptation is the only variable that matters.
Hit a plateau within 6 months
Not because they trained too little. Because their weights never adjusted to their real performance.
Are using the wrong loads today
Static programs ignore fatigue, sleep, stress. The bar doesn't know you had 4 hours of sleep.
Athletes should train on a static program
Your body changes after every session. Your program should too. Anything less is performance left on the floor.
The Adaptive Engine
Three stages. One continuous loop. No human bias. No generic AI.
LOG
Every set. Every rep. Every RPE.
You record what actually happened, not what the program said should happen. Load, reps, and perceived exertion.
ANALYZE
Performance vs. target. Every time.
The engine compares actual output against expected. It detects fatigue trends, RPE drift, and volume tolerance.
ADAPT
Next session, recalculated.
Load, volume, and exercise selection update automatically. The program becomes yours, session by session.
Same inputs always produce the same outputs. No black-box AI. No randomness. No "the algorithm decided." Every adjustment is explainable and traceable.
See How You
Should Be Training
A short analysis. The engine identifies your biggest training bottleneck from your own lifts and builds the block you actually need.
Three Steps.
Endless Adaptation.
Log Your Session
Record every set with load, reps, and RPE. The system needs reality, not theory.
Engine Analyzes Performance
The rule engine evaluates your output against target. Detects trends over 4-8 sessions.
Next Session Recalculates
Loads, volume, and exercises update automatically. You show up. The program is already adapted.
Built for
Serious Athletes
No beginner modes. No gamification. No fluff. Every feature exists because elite athletes need it.
Adaptive Load Engine
After every session, loads recalculate based on RPE, performance trend, and cumulative fatigue. Never too heavy. Never too light.
Injury-Aware Training
Input limitations. The engine substitutes or modifies affected movements automatically, maintaining stimulus without risk.
Competition Prep Blocks
Set a meet date. The engine builds backward, peaking your strength precisely for competition day, not a random Tuesday.
Strongman Events
Log Yoke, Farmers, Atlas Stones, Log Press. Proper periodization for implements, not a generic "core" replacement.
RPE Calibration
The engine learns your RPE patterns over time. It accounts for optimistic reporters and sandbagging, and corrects for both.
Every Decision Explained
The engine doesn't hide its logic. Every load change comes with a reason. You understand why, not just what.
From the world's top strongman ecosystem
Factual references only. Not official endorsements.
"Not Generic AI.
A Deterministic Engine."
BIG Z doesn't guess. It calculates. The difference matters when you're chasing a competition total or breaking through a plateau that's held for six months. Every adjustment has a reason. Every load has a basis.
Built with elite strongman expertise. Real-world methodology, not internet fitness advice. The system reflects how top-level strength athletes actually train, with data, precision, and zero tolerance for wasted effort.
