Enter the top weight from each of the last four to eight weeks, oldest first, one per line, and the page lays the movement out in numbers. You get the change against the previous week, how many weeks have passed since your last best, the average rate across the whole span, and the difference between the first and second halves. Lines written as "3, 235" with a week number in front are read correctly too.
Everything is arithmetic on your own entries. The average rate divides the gap between the last and first weeks by the number of intervals. The half comparison includes the middle week in both halves, works out a rate for each and subtracts them. A week counts as a new best only when it beats every earlier value, and the table marks those weeks. As of October 2026 no authoritative standard for how many flat weeks amount to a plateau is published.
For that reason this page never declares a plateau and prescribes no way to break one. It also does not predict future rates from training age or nutrition. Logged weights swing with equipment, spotting and daily condition, so avoid drawing conclusions from one or two weeks.
Frequently Asked Questions
No authoritative threshold is published. This tool counts consecutive weeks without a new best and makes no judgement.
The middle week belongs to both halves, giving each one at least two points. With fewer than four weeks the comparison is skipped.
Yes. A line such as "3, 235" is read with the second figure as the weight. Any line that is not numeric is reported by its line number.
