PR Log
Track personal records per exercise.
Overview
The PR Log keeps a clean record of personal records across every lift you care about. Each entry pairs an exercise name, date, weight, and reps, and the tool surfaces the best lift per exercise so you always know where the bar sits today. Squat, bench, deadlift, overhead press, weighted chin-up, hip thrust, front squat, snatch: name the lift and the log will track it.
Logging PRs separately from full session detail is deliberate. The full workout log captures every set; the PR log captures the moments worth bookmarking. Looking back at a year of training, the PR feed is the highlight reel that tells the story of how strong you have become and which lifts have stalled long enough to deserve a programming change.
How it works
When you enter a weight and rep count, the tool estimates the one-rep maximum on the fly using the average of the Epley and Brzycki formulas, so a 5RM at 100 kg shows roughly what your true single would carry. If the weight you are about to log beats your existing best for that exercise, a "New PR!" chip appears next to the submit button before you commit the entry.
The best-lifts panel pins the top entry per exercise to the top of the page, ranked by weight. The full entry list below preserves the chronology and flags whichever row is currently the best for each exercise. Switching units between kilograms and pounds is per-entry so a meet in pounds and a daily training log in kilograms coexist without confusion.
Examples
- Squat ladder: log every five-rep top set on squat day for a training block and watch the estimated one-rep max climb alongside the actual recorded weights.
- Variation tracking: log front squat and back squat as separate exercises to see the ratio shift as your front-rack mobility improves.
- Meet results: log competition singles with notes describing the platform, the weight class, and any judge calls.
- Returning to a lift: log the first session back on an exercise you have not trained in months as a baseline before you start adding load.
FAQ
How is the one-rep max estimated? The tool averages the Epley formula (weight times (1 plus reps divided by 30)) and the Brzycki formula (weight times 36 divided by (37 minus reps)). At low rep counts the two formulas agree closely; at higher reps they diverge and the average dampens the error.
Does it consider failed reps? No. Log only what you actually completed cleanly to the standard you want your PR record to reflect.
Can I track bodyweight movements? Yes. Log a chin-up with bodyweight in the weight field, or weighted variations with the added load. Be consistent within a single exercise name.
Why is the best lift ranked by weight rather than estimated one-rep max? Heaviest weight moved is the unambiguous record. Estimated one-rep max is useful comparative information but is, by definition, an estimate.
