Workout Volume Calculator and Rest Timer
Add each exercise to calculate total sets, reps and training volume. Then run a clean rest timer without leaving the page.
Build this workout.
Volume is calculated as sets × reps × weight for each exercise.
What workout volume can tell you.
Volume is one simple way to compare the amount of weighted work between sessions. Ten reps with 50 kg equals 500 kg of volume; three identical sets equal 1,500 kg.
- Enter the sets, reps and external weight for each exercise.
- Keep the same unit across the entire workout.
- Compare similar exercises and sessions instead of treating volume as a universal score.
Volume is only one part of training
Range of motion, effort, technique, exercise selection and recovery also matter. Bodyweight and timed movements are counted in sets and reps here but contribute zero weighted volume unless you enter a load.
Plan every set with Did You Lift.
Create complete weekly routines, set individual rep or time targets and let the rest timer start automatically.
Use the calculator with confidence.
Enter changing sets as separate rows
If repetitions or load change between sets, add separate rows with one set each. Three sets of ten at 50 kg total 1,500 kg of volume load; sets of 10, 8 and 8 at that load total 1,300 kg instead. Use actual results when reviewing a completed session.
The unit selector labels the entries; it does not convert existing numbers between kilograms and pounds. Keep one unit throughout. The rest timer is a visible browser countdown, so keep the page open and do not rely on a locked phone or suspended tab to produce a background alarm.
