The coaching console for Delta, the strength-training app your clients run themselves. You see their training and propose changes; they stay in charge of their own logbook.
Build a template once — days, exercises, methods — then assign it to every client who trains that way. Invites come second: a client who accepts should land in a program, not a blank.
Open any client to read their logbook. No editing, no body data — those views don't exist here. A client can correct or remove their own sessions, so entries can change or disappear.
The same catalogue the app uses. Picking one pins its key, so what you author and what your client logs are the same lift.
Each client decides on their phone: changes to anything they've customized wait for their OK — other updates apply on their own, and they'll always see what changed.
