General fitness apps count reps. Powerlifters need to know their squat went up 5kg over the last training block, their bench is stalling at the top, and their deadlift volume has been declining for three weeks. Iron Log tracks the numbers that matter for strength sports — compound PRs, bodyweight-relative strength, and per-muscle volume with barbell isolation.
Most workout trackers were built for the general gym-goer — someone doing 8 exercises per session across machines and dumbbells, tracking calories burned and workout streaks. The design reflects this: exercise selection is cluttered with isolation machines, PR tracking treats a lateral raise the same as a deadlift, and there's no way to isolate barbell compound volume from accessory work.
Powerlifting has specific needs: you care about a handful of movements deeply, you track in absolute weight rather than effort scores, you think in training blocks and peaking cycles, and you need to see your strength trajectory relative to your bodyweight over months, not just session-to-session changes.
Iron Log calculates a metric you won't find in other apps: the compound-median strength-to-bodyweight ratio. It takes your all-time best lift across four movement categories — Push, Pull, Hinge, Squat — finds the median of those four, and divides by your current bodyweight.
Why the median instead of the average? Because one outlier lift doesn't inflate the number. If your deadlift is 200kg but your bench is stuck at 80kg, the ratio reflects your overall strength level honestly rather than being pulled upward by one strong pattern. This gives you a single number that tracks meaningful progress over months and years — useful for intermediate and advanced lifters who need to see the long curve, not just whether today was a good day.
The ratio is displayed on the home screen with a week-over-week trend so you can see at a glance whether you're progressing, maintaining, or sliding back.
Iron Log tracks two PR types per exercise: heaviest single weight lifted (strength PR) and highest single-set volume in kg (volume PR). For powerlifters focused on moving maximal weight, the strength PR is the number that matters.
The all-time top lifts panel surfaces your five heaviest records across all exercises — this is your quick-glance SBD snapshot. A recent PRs section shows new records from the last 30 days so you can see which lifts are actively progressing. Warmup sets and blood flow restriction (BFR) sets are automatically excluded from PR calculations — only working sets count.
PRs fire in real time on the set row the instant you confirm. No waiting for a summary screen, no end-of-session review. You know immediately when a record falls.
Every exercise in the library is tagged with primary and secondary muscle groups at specific percentage splits. A Barbell Squat counts toward Legs (primary) and Glutes (secondary). A Conventional Deadlift distributes between Glutes, Back, and Legs. This means your weekly volume picture reflects actual muscle stimulus from compound movements, not just set counts.
The equipment filter in the analytics panel lets you scope your volume view to free weights only. If you're running a powerlifting program with barbell compounds and machine accessories, you can isolate just the barbell work to see whether your competition-relevant volume is adequate without the noise of cable crossovers and leg extensions.
Export your full training history as TXT or CSV — every session, every set, every weight, every timestamp. Paste it into an LLM and ask it to analyse your squat-bench-deadlift progression across the last training block, identify whether your volume distribution matches your programming intent, or flag when your session density suggests you need a deload.
The data is structured for this kind of analysis: set timestamps show rest periods between heavy singles versus back-off sets, session duration reveals training density, and the per-exercise weight history gives a clear progression curve across any time window you choose.
