KAYN SystemsAdaptive training engine · Berlin
Your session doesn't exist until you ask for it.
Built the moment you ask — from your readiness, your time, your equipment, your coach's plan.
01What adaptive actually means
The era of customised is over. The era of adaptive begins.
Most apps ship a fixed plan and edit the numbers. KAYN writes nothing in advance — it reads the day you turned up with, then builds from it.
Full strength, 60 minutes.
Progressive loading. Overhead work included. Short breathing close.
Nothing routed aroundRecovery-shaped, 30 minutes.
Extended-exhale breathing opens it. Low-load movement, aerobic flush.
Routed around · overhead pressing02Two systems, one engine
The body and the nervous system train together.
The physical systemFlipThe physical system
Load, volume and intensity move with what your body can handle today — not what the plan assumed last week. Progress keeps compounding.
The nervous systemFlipThe nervous system
KAYN reads your readiness signals — sleep, stress, recovery state — and shapes the session before you start, so training works with your nervous system.
03The sequence
Four steps. Then it compounds.
Assess
Onboarding builds your baseline: history, equipment, competing level, season phase.
Check in
Readiness, mental state, time, equipment, soreness by area. Thirty seconds.
The engine reads
Your day, your history, your coach's programming — in priority order, every time.
The session rebuilds
Right focus, right load, right equipment. Generated for today, not retrieved.
03 · BStep three, in the open
Priority order, every time.
Nothing is assembled in the dark. While the session builds, you watch the engine read each source in the same fixed order.
It gets sharper with use.
The engine remembers what you found trivial, what you declined and why, and how you actually respond.- Biasing toward hip-stable, core-controlled work.Movement screen
- You noted a squat limitation, so we picked supported strength.Today's check-in
Your session is ready
Rest 90s to keep each set clean and controlled.
A real session · the reasoning is on the surface
04What shaped today
You can see why.
Every session opens with what the engine considered — your coach's guidance, your movement assessment, your day's state. No black box.
A bad night changes the intensity. It never changes what you're training.
Flag an area as sore and the engine routes around it — or stops loading it entirely and hands the decision to a human.
A session that contradicts your schedule or assumes equipment you don't have never reaches the screen.
