A coach that
reads your log.
Text Jim what you lifted and how hard it felt. It tracks estimated 1RM, spots fatigue before you do, and writes next week around it. Nothing to install.
Free to start. No app. Your training data stays yours.
What Jim does
It knows how hard it actually felt.
Every set carries an RPE, so Jim knows the difference between 205 that flew up and 205 that nearly buried you. That's the whole signal.
It coaches you as you go.
Estimated 1RM, not raw weight — comparable across rep ranges. Loads come from your own trend, and a stalled lift gets backed off, never a PR attempt. Part of the paid tier.
It calls the deload before you break.
Rising effort at the same load, e1RM going flat, red check-ins stacking up — Jim reads all three and moves the deload, instead of waiting for week 8 on a calendar.
It works around what hurts.
Say your shoulder's bothering you and pressing swaps to a variation that spares it — for every week left in the block, not just today.

Questions
No. Jim lives in your messages app. If you can text, you can use it — no download, no account to open on your phone.
No. Signing up doesn't send anything. You text Jim first at (818) 601-1364, and that message is what activates your log and your reminders.
Reply STOP at any time and Jim stops texting you. Reply HELP for support info. You can start again later by texting in.
A general chatbot forgets. Jim keeps your training history as structured data, so “what did I squat last week” has a real answer and progressions are built off numbers you actually hit.
The log is free forever — text your sets, ask for your history, get PR recognition. The coaching tier is the paid part, and you can stay on free indefinitely.
No. Jim is a log with coaching layered on top. It isn't a doctor, physical therapist, or certified trainer, and it doesn't diagnose or treat injuries.
Text your first set.
Open your messages app and send Jim anything you lifted today. Jim texts back the terms, you reply YES, and your log exists. That's the whole onboarding.
