Reasoning with your data
Today is push day, but my right shoulder hurts when I press overhead. Should I change the routine?
Today in your plan: push (chest · shoulder · triceps).
Reported pain: right shoulder on the overhead press.
Overhead press and dips stress the cuff → I remove them today.
I keep the push stimulus with shoulder-safe angles.
I add rotator cuff activation before starting to prevent injury.
Done. I'm dropping the overhead press and the dips so we don't strain the shoulder, and we'll start with a rotator cuff warm-up. Today's session 👇

WHAT EVERYONE ASKS.

No. Just your phone. If you have dumbbells, barbells or machines, great — it uses them. If you only have your bodyweight, it works too. The plan adapts to exactly what you have.
Yes. When you set up your profile you tell it what equipment you have and whether you train at home or at the gym. The plan is built with exactly what you have, no exercises you can't do.

No. It's a model trained on periodization, biomechanics and real logs. Talking to it for 30 seconds will confirm that.
