Every session, and what it adds up to
Record the sets you actually did and the weight you actually were. The dashboard turns months of that into the few things worth knowing: whether each lift is going up, whether the week matched the plan, and whether a goal fits the date you gave it.
This is arithmetic, not medical advice. It adds up what you tell it and says how sure it is. Nothing you enter is uploaded — it is kept in this browser, which also means a browser that clears its storage takes it with it. Download a backup now and then.
Where you are
The last four weeks, against the four before them.
The last six months
NothingA hard day
Against the plan
Hard sets per muscle this week, beside what the planner asked for. A plan nobody follows is not a plan.
Is this lift going up?
Estimated maximum per session, fitted. Four sessions is the fewest that shows a direction.

One file, every fitness tool on this site: the log, the weigh-ins, your lifts and your plan.
Why this matters here more than usual. There is no account and no server, so this browser is the only place your training exists. Clearing site data, a new phone, or a browser that decides to tidy up will take it with it. A backup is a plain JSON file you keep yourself; restoring it on any device puts everything back.
What a log is for
Not memory — a phone remembers fine. A log is for the three questions you cannot answer without one: did the weight on the bar go up over months, did the work you planned actually happen, and is the thing you are chasing on the scale moving at a rate that matches the date you gave it. Each of those is invisible week to week and obvious over a season, and all three are on this page.
Hard sets, and why the count is lower than you think
A set counts here when it finished within a couple of reps of the point where another one was not happening — the same definition the planner uses, which is what makes "twelve planned, seven done" an honest sentence rather than two different words for two different things. Sets that stop well short do very little, so a session can feel long and busy and still move almost nothing. If your logged hard sets are far below your planned ones, that is usually the reason rather than missed sessions.
Why four sessions before it draws a trend
A top set moves by more between a good night's sleep and a bad one than a fortnight of training moves it. Fit a line to three points and you will get a confident slope out of noise every time. Four is the fewest that supports a direction at all, and even then the page says when the slope is not bigger than the scatter around it — because "going up" and "not yet distinguishable from noise" are different answers and only one of them should change what you do.
A goal with a date is arithmetic; without one it is a wish
"Lose eight kilos" has no failure condition. "Lose eight kilos by the first of June" divides into a rate, and the rate can be checked against what bodies actually do: roughly one per cent of bodyweight a week is the most that comes off without taking muscle with it, and muscle goes on far slower than almost anyone expects — about half a per cent of bodyweight a week for someone new, less after that. Most of the time what this page tells you is that the goal is fine and the date is the problem, which is a much easier thing to fix.
Common questions
Does this replace the weight tool?
No, and it does not keep its own copy either. Weigh-ins recorded here go into the same store the weight tool reads, so the trend, the adaptive calorie figure and the body-fat estimate there all see them immediately. Two tools disagreeing about what you weigh would be worse than either of them being wrong.
Can I log something that is not in your exercise list?
Yes — type anything. It is recorded and counted in your volume and your sets. The one thing it cannot do is land on a muscle in the "against the plan" comparison, because nothing has matched it to one; those sets are shown as unattributed rather than quietly assigned somewhere or quietly dropped.
What happens if I clear my browser data?
It is gone. There is no account and no copy anywhere else — that is the trade for nothing being uploaded. Download a backup occasionally and keep it somewhere you would keep a photo.
Does the backup include my other fitness tools?
Yes. One file holds the log, every weigh-in, the lifts recorded in the strength tool and the plan from the muscle planner. Restoring it on a new device puts all of them back at once, which is what somebody setting up a new phone actually wants.
Why is my volume zero for bodyweight exercises?
Volume here is kilograms moved, and a press-up moves no kilograms the page knows about. That is why set count sits next to it: for bodyweight training the sets are the number that means something, and the planner's ladders are how that progresses.
