Personal records and estimated 1RM, tracked automatically

An estimated one-rep max (1RM) converts any hard set, say 100 kg for 5 reps, into the single-rep strength it implies, so you can measure progress without max-out attempts. Mekimeki calculates estimated 1RM from your logged sets automatically and flags new personal records the moment you hit them.

How does Mekimeki estimate 1RM?

Three formula options: Brzycki, Epley, and a hybrid of the two. Pick the formula you prefer in settings and Mekimeki applies it across your history.

All 1RM formulas are estimates derived from the relationship between weight and reps. They're most accurate at low rep counts, and best read as a consistent yardstick rather than a guaranteed max.

What counts as a personal record?

As you log sets in your workout log, Mekimeki compares them against your history for that exercise and flags a PR the moment a set implies a new best estimated 1RM. Warm-up sets are automatically excluded, so a light ramp-up set never pollutes your records.

Why estimated 1RM beats testing your max

Testing a true 1RM is fatiguing, risky, and disruptive to a training week. An estimated 1RM gives you the same signal (is my strength going up?) from the working sets you were already doing. Watching it trend upward over weeks is one of the clearest confirmations that your progressive overload is working.
