WORKOUT TRACKING
A workout tracker that plans the next week, not just records the last one.
Per-set logging, RPE, and PRs — the table stakes. The difference is the AI coach that builds your week, reads what you actually did, and adjusts.
Most workout trackers are spreadsheets with a nicer font
They are good at one thing: storing what you did. You finish a set, you type the weight and reps, and the number goes in a row. Useful — but it is bookkeeping. The app never tells you what to do next, and it never reacts when a session goes badly.
So you end up with a clean log and no plan. The thinking — what to train, when to push, when to back off — stays entirely on you. That is the part that is actually hard, and it is the part the tracker leaves untouched.
FitnessGrid logs every set, RPE, and PR the way you would expect. Then the coach uses that history: it plans the week ahead, and when a session comes in heavy or light, it adapts the next one instead of waiting for you to notice.
HOW IT WORKS
From a sentence to a plan
Tell the coach the goal
Building muscle, getting stronger, staying consistent. It plans a week — Monday to Sunday — around it.
Run the session
Tap a set as you finish it. Log weight, reps, and RPE. PRs surface on their own.
Coach reads the session
A working set at RPE 9 when it should have been 7 is a signal. The coach sees it.
Next week adapts
Loads, volume, and rest-day placement shift based on what your log actually says — not a fixed template.
Per-set logging
Weight, reps, and RPE on every set. The granularity a real training log needs, without the spreadsheet.
RPE as a first-class input
RPE is not a note field. The coach reads it to judge whether the load was right and what the next session should be.
PRs, tracked automatically
Personal records surface as you hit them. No separate PR sheet to maintain.
The weekly grid
Your training lives in a seven-day grid you can see at a glance. The coach fills it; you run it.
Adaptive, not fixed
A bad week of sleep, a missed session, a heavy day — the plan bends around real life instead of breaking.
Training and nutrition together
Sets and macros in one app. The coach plans them as one system, because your body treats them as one.
QUESTIONS
Common questions
Yes. FitnessGrid logs every set with weight, reps, and RPE, and surfaces PRs automatically. Per-set logging is the baseline, not a premium feature.
