Automatic Personal Records and 1RM Tracking | Strongbro
Quick answer
Strongbro checks every logged set against your history and records two kinds of PR automatically: your best weight at each rep count, and your estimated one-rep max per exercise. The Records screen shows the heaviest lift per exercise per month, so progress reads at a glance.
A PR you have to notice yourself is a PR you'll miss. Strongbro watches every set so you don't have to.
Two records per exercise
- Weight at reps — your best 80 kg × 8 is a different record from your best 100 kg × 1. Each rep count keeps its own.
- Estimated 1RM — computed from your best set, so exercises you never max out on still show a strength trend.
A timeline that reads like one
The Records screen collapses the noise: one row per exercise per month, showing the heaviest lift and the day it happened. Fourteen rows tell you more than four hundred would.
Wired into everything
New records fire the celebration you actually want — a notification naming the lift and the number — and feed the rank and insights screens. Log with voice or keypad; the records don't care how the set arrived.
Frequently asked questions
How is the estimated 1RM calculated?
With the Brzycki formula from your best weight-and-reps set. It's an estimate for tracking direction, not a licence to attempt a true max — the trend is the point.
Do I need to mark a set as a PR attempt?
No. Every set is checked automatically as it's saved, whether it came from voice or the keypad. When a set beats your history, the record updates and the app tells you.
Can old workouts create records?
Yes. Records carry the date of the set that earned them, so importing or back-logging a session slots into the timeline correctly.
