HOW TO USE LEAN:
1) Take four photos and let the AI read your body in about a minute.
2) Find out exactly which muscle group is holding you back.
3) Train the plan built around that weak point, not a generic split.
Most fitness apps track what you do.
LEAN tracks what you're made of.
The scan estimates your body fat percentage and scores nine areas out of 100:
overall, potential, body fat, chest, back, shoulders, biceps, triceps and core.
No tape measure. No calipers. No clinic appointment.
A single body fat number tells you very little on its own. Knowing your back is
sitting ten points behind your shoulders tells you what to do on Monday.
That's the difference. Direction instead of guesswork.
Your calorie and macro targets are built from your own scan, your weight, and
how you actually spend your day. Walk more and the target moves with you. Say
what you ate out loud and LEAN logs it in seconds.
Training programmes are aimed at your lowest scores. Log your sets as you go.
Personal records are detected automatically.
An AI coach that has seen your numbers, your targets and what you've actually
been lifting. Not generic advice with your name pasted on top.
Scan again in a few weeks and see exactly what moved.
BEING STRAIGHT WITH YOU
LEAN produces estimates, not laboratory measurements. Body composition worked
out from photographs will differ from a DEXA scan. What it's good at is
consistency. Scan the same way each time and the direction of change is
reliable, which is the part that matters when you're training.
YOUR PHOTOS
Analysed, then deleted, within minutes. Never kept, never looked at by a
person, never used to train AI models. Delete your account and everything in it
from inside the app whenever you want.
You don't just train. You train with direction.
Your body is unique. Your plan should be too.
Download LEAN and find out where you actually stand.
