The Lythe Method

Understand every
layer of motion.

Full body musculature
01
Full-body Mapping
01
Skeletal mapping
in real time

Lythe captures how your body moves using just your phone’s camera. No wearables & no markers. Just you and a clear, moment-by-moment view of your movement.

Hip joint anatomy
02
Joint-level Context
02
Restriction
sites identified

From the data, Lythe determines which joints are limiting your range. Hip flexor tightness, hamstring restriction, thoracic immobility — named precisely, not guessed.

Back musculature
03
Posterior Chain
03
Fascia and
muscle context

Every session adds a layer to your clinical archive. The posterior chain — lumbar fascia, erector spinae, hamstrings — mapped across time so you can see change, not just feel it.

What Lythe Does

Built around your body,
not a generic plan.

01
Real-time angle measurement
Your camera calculates joint angles frame-by-frame. No guesswork — live data from the body you're actually in.
02
Goal-based progression
Choose splits, forward fold, pancake, or overhead. Lythe plots the shortest path to your target angle.
03
Session trend analysis
8-session rolling trend lines show whether you're gaining, plateauing, or overreaching — before injury.
04
Anatomical context
Lythe names the muscle or fascia limiting you — so you stretch what actually needs it.
05
Technique guide library
Protocol cards matched to your restriction profile — from pelvic tilt correction to posterior chain activation.
06
On-device ML
All pose detection runs locally. Your camera feed never leaves your phone. Private by default.

Every restriction Lythe identifies maps to a curated protocol. Precise guidance based on where your body actually is — not where a generic plan assumes you should be.

Clinical Archive

Precision in movement
leads to longevity.

Lythe maintains a permanent record of your mobility. A clinical data archive that grows with every session — becoming one of the most precise pictures of your body's movement capacity ever assembled.

"Your restriction originates primarily in the lower lumbar fascia. This 20° gap between your baseline and the target is likely contributing to the morning stiffness you reported."
