How to calculate training volume
Session volume load = weight × reps per set × sets Weekly volume load = session volume load × sessions per week
Worked example. Volume load per session: 3,240 lb·reps.
Example inputs — Weight units: Pounds (lb); Weight per rep: 135; Reps per set: 8; Sets per session: 3; Sessions per week: 2. Starting values are illustrative.
One exercise with the same weight and reps in every set. Volume load does not measure calories burned or predict muscle growth.

How it works
Volume load is a simple training-log calculation: multiply the weight moved by the repetitions and sets for one exercise. Use the same convention each time: include the bar for barbell lifts, and enter the combined dumbbell load if each repetition moves both dumbbells. Compare sessions of the same exercise, range of motion and technique. More volume is not automatically better; effort, recovery, exercise choice and how close sets are to fatigue also matter. If loads or repetitions differ between sets, calculate each set separately and add the totals rather than entering an unweighted average.

Assumptions & limitations
- Identical load and reps across the entered sets.
- Weekly sessions repeat the same exercise prescription.
- Tracks external load only; bodyweight work and machine leverage are not standardized.

Frequently asked questions
Is volume load the same as the number of hard sets?
No. Volume load multiplies external weight and repetitions. Hard-set counts describe something different and depend on effort. Neither alone predicts training results.
Should I count one or both dumbbells?
If a repetition moves both dumbbells, enter their combined weight. For single-arm repetitions, choose a per-arm or combined convention and keep it consistent.
Does increasing weekly volume guarantee muscle gain?
No. Recovery, effort, technique, nutrition and individual response matter. This arithmetic is not a personalized progression plan.
