A9Core
A coach that actually pays attention.
A9Core learns how you train and rebuilds your program around it — sets, reps, and rest adjusted session to session based on your performance and recovery, not a fixed template. Log a lift in seconds; A9Core handles the planning.

What to expect
Adaptive programming
Your plan updates automatically as you get stronger, miss a session, or come back from a break. No more following week 6 of a template written for someone else.
Fast logging
Log sets in a couple of taps mid-workout — no spreadsheets, no typing paragraphs between sets while your rest timer runs out.
Progress that means something
See strength trends over time instead of a wall of disconnected numbers. Know whether this month actually beat last month.
Fits your gym
Works with bodyweight, barbell, dumbbell, or machine-only setups — the plan bends to the equipment you have, not the other way around.
How it works
Log the work
Tap through your session as you lift — sets, reps, weight, done.
A9Core adapts
It reads your performance and recovery, then rebuilds what comes next.
Progress compounds
Each session builds on the last — trends you can see, not guess at.
Where it stands
A9Core is in active development. The adaptive engine is being built first — it's the part that has to be right before anything else matters. Everything on this page is a concept preview; real screenshots land as the interface settles.
