"The 3D anatomy overlay changed how I coach. My clients finally understand why we do the cues we do — and they retain form between sessions because they’ve seen the muscle fire."
"As a yoga teacher with 15 years on the mat, I’ve never had a tool that visually backs up my anatomical cues this clearly. The therapeutic library alone is worth the subscription."
"Front-rack mobility was killing my cleans. The CrossFit mobility library + 3D shoulder breakdown got me to a stable rack position in 6 weeks. PR’d my clean by 8kg."
Training without understanding movement
is training blind.
Most platforms give you reps and sets. None teach you how your body actually moves — the planes, the forces, the muscle chains. That gap causes plateaus, compensations, and injuries.
Without Movement Science
- No understanding of movement planes or joint mechanics
- Generic programs that ignore biomechanical individuality
- Zero visibility into muscle activation patterns
- Compensations and force imbalances go undetected
With FixAxis Intelligence
- Real-time 3D anatomy mapped across all three movement planes
- AI coaching adapted to your biomechanical profile
- See every muscle chain activate as force transfers through your body
- Biomechanical feedback catches compensations before they become injuries
Movement intelligence in 3 steps.
No guesswork. No generic plans. A system that understands human movement and coaches accordingly.

Planes, Axes & Movement Patternsdecoded by Dr. Atlas
Every exercise exists within three anatomical planes and around three axes. Master adduction, abduction, flexion, extension, and rotation — the foundation of safe, effective training.
“Every movement begins with three planes and three axes. Master these — master your body.”
Sagittal Plane
× Frontal AxisFlexion · Extension
Splits left and right. Squats, lunges, curls — they all live here.
Frontal Plane
× Sagittal AxisAdduction · Abduction
Splits front from back. Lateral raises, side lunges, jumping jacks.
Transverse Plane
× Longitudinal AxisRotation · Circumduction
Splits top from bottom. Twists, throws, cable rotations — rotational power.
Toward / away from the midline, decreasing / increasing joint angles, and turning around an axis — every exercise is built from these patterns.
Explore the Science of Movement
Six integrated movement systems covering every dimension of human biomechanics — from explosive force production to neuromuscular restoration.
All 11 Movement Categories + Nutrition
Each category features biomechanical analysis and real-time muscle activation mapping
Your Movement Science Team
Alex
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
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
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.
Trusted by serious athletes & professionals
Movement scientists, personal trainers, physiotherapists, and athletes trust FixAxis to teach biomechanics visually.
