Key takeaways:
A set and rep tracker logs individual working sets — the actual weight and reps you moved — rather than a session summary. It's the tool for answering "is my squat actually getting stronger" with real numbers instead of a feeling, because it captures every set on every exercise separately and lets you chart just one lift at a time.
This is deliberately more granular than a general workout log: where a session log tells you that you trained, this tells you exactly what you lifted, and whether it's trending up.
Comparing a set of 5 reps at 80kg to a set of 3 reps at 85kg isn't straightforward at a glance — estimated 1RM (via the Epley formula, weight × (1 + reps ÷ 30)) puts every set on the same scale so the chart tracks real strength trend rather than reps-and-weight noise. It's an estimate, not a tested max, and gets less reliable above about 10–12 reps, but it's a solid, consistent way to compare sets logged weeks apart.
Pair this with the Workout Log for the session-level picture, and the Body Measurement Tracker to track how strength changes show up physically.
How is this different from the Workout Log?
The Workout Log records a session as a whole. This tracks individual sets — exercise, weight and reps, one row per set — so you can see strength progression on a specific lift over weeks or months, not just that you trained that day.
What is estimated 1RM and how is it calculated?
Estimated one-rep max uses the Epley formula: weight × (1 + reps ÷ 30). It's a rough estimate from a working set, not a substitute for actually testing a true max, and accuracy drops for sets over about 10–12 reps.
Where is my strength log stored?
Entirely in this browser's local storage, on this device. Nothing is uploaded. Export a CSV as a backup or to share with a coach.
Can I track more than one exercise?
Yes — log any exercise by name and use the chart dropdown to pick which one to view. Each exercise builds its own progression chart from its own logged sets.
Can I edit or delete a set?
Delete any row with the ✕ button. There's no in-place edit — remove the set and log it again with corrected numbers.
Is this training or medical advice?
No. This is a record-keeping tool for the numbers you lift — it doesn't prescribe weights, reps or programmes. For programme design, speak with a qualified strength coach.
