The Training Volume Calculator adds up the total mechanical work in a workout — its volume load or 'tonnage' — across as many sets as you like. Enter each line as sets × reps × weight, add an optional bodyweight, and it totals everything live in your browser with nothing uploaded.
Volume load is the sum of sets × reps × weight for every line: three sets of five reps at 100 equals 1,500, and the tool adds each line together for the workout total. It also reports total reps (the sum of sets × reps) and, if you enter your bodyweight, relative volume — total tonnage ÷ bodyweight — expressed as a multiple of your bodyweight so you can compare sessions fairly as you get stronger or change weight.
Tracking volume load over weeks is a simple way to monitor progressive overload and manage fatigue. This is general fitness information, not medical advice — the weight unit is only a label, so keep your entries consistent (all lb or all kg) for meaningful totals.
Frequently asked questions
What exactly is volume load or tonnage?
It is sets × reps × weight summed across every set, so 5 × 5 × 100 = 2,500. Adding all your lines gives the total tonnage — a single number for the mechanical work done in the session.
How is relative volume calculated?
It divides total volume load by your bodyweight, shown as a multiple (e.g. 40×). It lets lifters of different sizes compare training volume, and tracks how your work scales as your bodyweight changes.
Should I count warm-up sets?
That is up to you and your program. Many lifters log only working sets for a cleaner overload signal, but you can add every set — just stay consistent from session to session so the trend is meaningful.
Does the weight unit change the result?
No — the unit is only a label on the totals, so enter everything in the same unit (all lb or all kg). This is general fitness information, not medical advice.
