1.9.0 — your coach shows its work

A program you don't understand is a program you quietly stop trusting.

You get handed six exercises and a set count, and somewhere in week three you start wondering whether any of it was chosen for you or just dealt off the top of a deck. 1.9.0 is about answering that — showing the reasoning, letting you argue with it, and telling you honestly whether it's working.

Why this program

There's a new row above your week. Open it and your coach explains itself.

First a short note in its own words, then the facts that actually shaped your plan — every muscle trained twice a week, the volume you can recover from, the injury it's working around. One line each, with the full explanation only if you want it. Under that, your week day by day: what each day trains, and inside it, why each exercise is there.

It reads your current plan, not the one you were given on day one. Swap an exercise or adjust a day and the reasoning updates with it, so it can't drift into describing a program you no longer have.

The onboarding "Your program is ready" card now lists the same facts and links straight through. And once you've read the breakdown, opening an exercise from your day sheet also tells you why it's in your plan. Browsing the catalog still doesn't — those are facts about your program, not trivia about the lift.

Tell your coach what to change

Reasoning you can't reply to is a lecture. So there's a box at the bottom of that sheet.

Type one line — "more arm work, easier lower days" — and your coach reworks the rest of the block around it. Sessions you already logged stay exactly as they are. Nothing you did gets rewritten.

What comes back is a receipt, not a conversation:

• What changed, with the concrete edit it made.
• What was heard but isn't this program's job — your 10k, your nutrition — acknowledged rather than silently dropped.
• What stayed the same, and why.

And "Put it back" undoes the whole thing in one tap, so asking never costs you anything. If it genuinely can't undo — you've logged a session against the new plan since — it says so plainly instead of failing halfway. Keep the change and your week and Ready card redraw as the new plan.

Is it working? Now the answer includes your body

Strength charts tell you one half of the story. If you're eating for a goal, the other half is what your body is actually doing about it.

Body change covers the last eight weeks: your weight against your goal pace, your strength trend, and — when you have scale or Apple Health readings — how much of the change was fat and how much was muscle. Next to it, what you actually burn each day and how well calibrated that number is by now, four weeks of logged eating days, and your recent weekly reviews.

Tap into the detail screen for 4 / 8 / 12-week views and three charts, plus a short, unglamorous "How this is measured" — because a fat-versus-muscle split you can't interrogate is just a number that flatters you. Without body-composition readings, that third panel becomes a link to connect a scale instead of guessing.

Every verdict on the page comes from the server, computed from what you logged. Nothing on it is a vibe.

Adjust now moves the whole muscle group

A fix worth its own heading, because the old behaviour quietly did less than it promised.

Asking for more Back only ever touched your lats — so if your rows were built around your upper back, nothing moved. Legs skipped calves and adductors. Shoulders left out rear delts. Arms left out forearms.

Each group now covers what it says: Back reaches lats, upper back and traps; Legs adds calves and adductors; Shoulders covers all three delt heads; Arms includes forearms. The same tap now changes the sets you expected it to.

Core and lower back stay out of it on purpose. They're stabilisers that already pick up work from everything else you lift, so nothing quietly adds or removes their sets behind a tap you made for something else.

Getting a plan is easy. Trusting one is the hard part, and you don't get there by being told to. You get there by being shown the reasoning, being allowed to push back on it, and being told the truth about the results.

Get it on the App Store — and tell me what breaks. That's still how this gets better.
