Training Volume
Looking at the weight alone hides the difference between 3×5 and 5×10. Multiplying all three gives volume, which is closer to the work the muscle actually did and is the usual basis for comparing weekly load.

Formula
Training volume = Weight lifted (kg) × Reps × Sets
Equal volume is not equal stress: heavy weight taxes the nervous system, high reps tax metabolism. Matching volume is not the whole story.
What to enter

Frequently asked questions
Q. How is Training Volume calculated?
Training volume = Weight lifted (kg) × Reps × Sets — Looking at the weight alone hides the difference between 3×5 and 5×10. Multiplying all three gives volume, which is closer to the work the muscle actually did and is the usual basis for comparing weekly load.
Q. Can you walk through an example?
With Weight lifted (kg) 80kg, Reps 8, Sets 4sets, the answer is Training volume 2,560kg.
Q. What do I need to enter?
Enter Weight lifted (kg), Reps, Sets. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Weight lifted (kg) (kg) moves the answer to Weight lifted (kg) (kg) 40 → Training volume (kg) 1,280 and Weight lifted (kg) (kg) 160 → Training volume (kg) 5,120. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
Equal volume is not equal stress: heavy weight taxes the nervous system, high reps tax metabolism. Matching volume is not the whole story.
