Workout Log
Log sets, reps and weight; track personal bests, estimated 1RM and session volume.
About this tool
Pick the date, type the exercise (suggestions appear), enter sets, reps and weight, and log it. The tool groups entries by session, keeps a personal best per exercise with an estimated one-rep max, shows session volume, and exports the whole log as CSV. Data lives in this browser only.
The numbers that make training work
Progressive overload — doing slightly more over time — is the principle behind every strength programme, and it only works if you know what you did last time. A log is the whole method: the same lift, one more rep or a small jump in weight, week after week. This tool keeps the three figures that matter: the best set per exercise, an estimated one-rep max from it (Epley: weight × (1 + reps ÷ 30), reliable up to about ten reps), and the session's total volume (sets × reps × weight), which is the fatigue and progress measure programmes are written around. It is deliberately a notebook, not a coach: no programme, no rest timer, no sync, nothing uploaded — and the estimated max is a planning number, not an invitation to test it without a spotter. General fitness information, not medical advice. The one rep max calculator compares formulas, the interval timer times rest periods, the heart rate zones calculator covers cardio days, and the protein intake calculator the recovery.
Frequently asked questions
How is the 1RM estimated?
With the Epley formula: weight × (1 + reps/30). A set of 8 at 80 kg estimates about 101 kg. Accuracy falls beyond ten reps; a single at the actual max is the only true test.
Can I log bodyweight exercises?
Yes — enter 0 weight, or your bodyweight plus any added load, and be consistent so the volume figure stays comparable.
Does it sync with my phone?
No. It stores the log in the browser you use; export CSV to move it. Nothing is uploaded.
Can I track cardio?
It is built for sets and reps. Log a run as ‘Run’ with distance in the weight field if you like, but the pace calculator is the better tool.
