Praxis Motion Lab

Praxis turns any phone video of a movement into a structured biomechanics report — no wearables, no markers, no lab.

Film a squat, deadlift, jump, sprint, or sport skill. Praxis reads the movement from the video and returns a clear breakdown: what's working, what to fix, and why — in language matched to who you are.

WHAT PRAXIS MEASURES • Joint angles and range of motion through the full movement • Rep timing, tempo, and velocity • Left/right symmetry and compensation patterns • Jump metrics — flight time, contact time, reactive strength • Sprint and change-of-direction mechanics • Coaching that ties each cue to the data behind it

BUILT FOR HOW YOU TRAIN • Athlete — performance-focused cues and programming direction • Coach — per-athlete profiles and roster-ready summaries • Clinician — structured, terminology-aware movement observations • Everyday — plain-language guidance to move and train better

HOW IT WORKS

1. Record or upload a video (single phone is all you need).
2. Praxis extracts pose and computes the metrics on-device.
3. You get an instant, readable report with prioritized coaching.

Optional two-phone capture adds a second angle over your local network for a fuller 3D picture. LiDAR and high-frame-rate capture are supported on compatible devices.

PRIVACY Your videos are processed to produce your analysis. You control what's saved, and you can delete your account and associated data at any time from Profile. Praxis does not use your data for advertising or tracking.

IMPORTANT Praxis is an educational movement-analysis and coaching tool. It is NOT a medical device. It does not diagnose, treat, or prevent any condition and is not a substitute for professional medical, physical-therapy, or clinical advice. Always consult a qualified professional for any pain, injury, post-surgical, or return-to-play decision. Use Praxis as one input among many in your training, coaching, or clinical decision-making.
