Understanding Human Movement at the Deepest Level
FixAxis maps 9,000+ exercises across movement planes, axes, and muscle chains — transforming exercise science into interactive 3D visualization anyone can understand.
Movement Science for Everyone
Most people exercise without understanding how their body moves. They follow routines without knowing which muscles activate, which joints bear load, or why certain movements feel wrong. This knowledge gap leads to injuries, plateaus, and frustration.
FixAxis exists to close that gap. We combine biomechanical science with AI-powered visualization to make movement intelligence accessible — whether you're a beginner learning your first squat or a physiotherapist designing rehabilitation protocols.
Map every exercise to its biomechanical fundamentals: planes of motion, muscle chains, joint actions, and force vectors.
Visualize what happens beneath the skin with real-time 3D anatomical overlays powered by movement science.
Coach with evidence-based protocols grounded in ACSM, NSCA, NASM, and peer-reviewed research.
Four Pillars of Movement Intelligence
Every feature we build rests on these four interconnected pillars.
Evidence-Based Science
Every exercise profile is built from peer-reviewed biomechanical research — ACSM guidelines, NSCA protocols, NASM corrective frameworks, and ExRx movement analysis.
3D Biomechanical Visualization
Real-time anatomical overlays show muscle activation patterns, joint mechanics, and force vectors across sagittal, frontal, and transverse planes.
Movement Mapping
9,000+ exercises classified by movement type, muscle chain, equipment, difficulty, and biomechanical profile — creating the most comprehensive movement database available.
AI Movement Coaching
Specialized AI coaches analyze your movement patterns, identify compensatory behaviors, and design progressive protocols tailored to your biomechanical needs.
How FixAxis Works
Map the Movement
Every exercise is profiled across 25+ biomechanical dimensions — from prime movers and stabilizers to joint ROM requirements and breathing cues.
Visualize the Science
Dr. Atlas renders real-time 3D anatomy overlays showing which muscles fire, how force transfers, and what each joint does during every rep.
Coach with Intelligence
Alex and Maya deliver evidence-based coaching cues specific to your movement — form corrections, breathing patterns, and progression paths.
Track & Progress
Monitor movement quality over time. Progressive overload meets biomechanical awareness — so you get stronger and move better.
Meet Your AI Specialists
Three specialized AI systems, each approaching human movement from a different scientific lens.
Alex
Strength Science & Athletic Performance
Alex is your Strength Science & Athletic Performance specialist — CSCS-certified with deep expertise in force production, ground reaction forces, and metabolic conditioning. He maps every exercise to its biomechanical fundamentals: which planes you move through, which muscle chains fire, and how force transfers through your body.
Maya
Mobility Science & Movement Restoration
Maya is your Mobility Science & Movement Restoration specialist — certified in yoga therapy and physical therapy with deep expertise in neuromuscular control, joint mechanics, and compensatory pattern correction. She designs evidence-based protocols that restore movement quality at the joint level.
Dr. Atlas
Biomechanics Intelligence Engine
Dr. Atlas is the Biomechanics Intelligence Engine — a movement science AI that decodes what happens beneath the skin during every rep. With real-time 3D anatomical overlays, Atlas visualizes muscle activation across planes and axes, maps force vectors, and teaches the physics of human movement.
What We Stand For
Safety First
Every exercise includes injury prevention cues, common mistake analysis, and regression options. Movement quality always comes before intensity.
Evidence-Based
Our content is grounded in peer-reviewed research from ACSM, NSCA, NASM, and leading biomechanics literature — never guesswork.
Accessible to All
From beginners to elite athletes, from personal trainers to physiotherapists — movement intelligence should be available to everyone.
Globally Inclusive
Available in 8 languages with culturally adapted content. Human movement is universal — our platform should be too.
