What this result means
Volume load is sets × reps × weight. Enter one exercise or working-set block to calculate session tonnage, total reps, and projected weekly volume.
Volume load = sets × reps × external load.
Use volume for like-for-like comparisons
Volume load is useful when exercise, range of motion, equipment, and technique remain similar. It can show that the same load moved for more total reps or that weekly work increased.
Do not compare different exercises solely by tonnage. Mechanical demands and effective load differ.
Volume is not training quality
The formula does not include effort, technique, proximity to failure, recovery, or which muscles limited the set. A higher result is not automatically a better workout.
Use the result beside working-set count, performance, and effort—not as a score to maximize.
Frequently asked questions
What is workout volume?
A common definition is sets × reps × load. Coaches also use volume to mean total working sets or hard sets.
Should warm-up sets count?
They can be counted separately, but progression summaries often focus on working sets.
Is more volume always better?
No. The useful amount is specific to the goal and must remain recoverable.

LogFast calculates volume from completed working sets, then connects it to exercise frequency, effort, and strength trends rather than leaving it as an isolated total.
