How BBody works, and what it is for

Four answers, then a plan

Setting up asks for four things: how much training you have behind you, what you are training for, how many days a week you can give it, and how long a session can realistically be. Nothing else is required to start.

From those, the coach writes a weekly plan — which days, which movements, how many sets, what rep range. Each day becomes a real session with a prescription you can look at before you start, not a label like “upper body” that you have to interpret.

A session, start to finish

Opening the day's workout shows the whole list, with each exercise's prescription and what you did last time. Starting it switches to a guided view: one exercise at a time, with its instructions and a demonstration loaded for you.

• Record what you actually did — reps, load, duration, distance, effort — as you finish each exercise.
• Move freely with previous, next, or straight to a specific exercise. Navigating never logs anything by itself.
• Skip an exercise to mark it as not done today without touching the recurring plan.
• Finish at a review screen, where you can go back to anything unfinished and add a note about the session.

The day you actually have

Before training you can tell it two things: how many minutes you really have, and how you feel on a scale of one to five. It adapts the session to both.

What it does is deliberately bounded, because an adaptation you cannot predict is one you stop trusting. Low readiness reduces volume conservatively. Normal readiness restores the full session, within whatever time you said you had. It never raises the loads you were prescribed. Repeating the check-in does not stack reductions on top of each other, and raising the time available brings the work back rather than inventing more. Anything you have already logged is left alone, and your recurring plan is untouched — this is today only.

Changing the plan itself

Individual exercises can be edited, replaced or removed, and the scope is always explicit. A replacement applies to today. A removal asks whether you mean today or every week. Editing a prescription applies to that slot in the plan going forward, not to every exercise that happens to share the same name.

You can also add exercises from the catalogue into a planned or in-progress session, choosing whether each belongs in the warm-up, the main work, conditioning or the cool-down. Added work extends the session rather than silently displacing something else.

It keeps working without a signal

The day's workout is downloaded to the device, so a basement gym with no reception is not a problem. Sets are recorded locally while you train and sync to your account when the connection returns. Nothing waits on the network between finishing a set and seeing the number.

Installing it as an app gets you the same thing without browser chrome. Updates are offered rather than applied: it will not reload itself underneath you mid-session and lose a form you had half filled in.

What it does not do

It does not log sets individually yet. The values you enter are applied to every prescribed set of that exercise, and the form says so rather than implying otherwise. There are no push notifications, so nothing nags you.

It is also not medical advice, and it does not diagnose or treat anything. Your training records are yours: deleting your account removes the profile, the plans, every session and every result, along with the tokens any connected client was issued.
