Who touches it
Three surfaces, one record
A gym is three jobs happening at the same time. Each gets its own surface. All three write to the same record, so nobody reconciles anything by hand.
The coach
Drafts in minutes, approved by a human.
An assessment goes in; a four-week block comes out, ordered and slotted. Every exercise carries the reasoning that selected it, so an edit is a decision a coach can defend rather than an override of a black box.
The athlete
Logged on the floor, not after it.
The week, the session, the set — on a phone, as it happens. What gets logged is what the next block is built from.
The front desk
The half that decides whether a gym runs.
Leads, memberships, bookings, waivers, attendance, payments. Nothing to do with programming, and everything to do with whether the programming ever reaches anyone.
