Training Volume Calculator
Estimate workout volume from sets, reps and load, then scale it to weekly volume so progressive overload is easier to track.

Track volume load for one exercise
This tool totals the external load repeated across equal sets, then scales that exercise to a week. It reports volume load in kg, not calories burned or a measure of muscle growth.
Formulas
Session volume load = sets × reps per set × load in kg. Weekly volume load = session volume load × sessions per week. Total reps per session = sets × reps per set.
Enter a consistent exercise block
- Enter the number of sets and the same number of reps completed in each set.
- Enter the load per repetition in kg. Use a consistent convention, such as the full barbell weight or the combined weight of two dumbbells.
- Enter how often that same exercise block is repeated each week.
- Calculate and compare the session total, weekly total and reps. If sets use different reps or loads, calculate each block separately and add the totals.
Worked training-volume examples
Two identical sessions
Four sets × 10 reps × 50 kg = 2,000 kg per session. Repeating the block twice a week gives 4,000 kg weekly volume load and 40 reps per session.
Adding reps while keeping the load
Four sets × 12 reps × 50 kg = 2,400 kg per session, or 4,800 kg across two identical sessions. This is a 20% increase in calculated volume load. It does not establish whether the increase is appropriate for recovery.
A session with unequal sets
Two sets of 10 at 50 kg contribute 1,000 kg. Two sets of 8 at 55 kg contribute 880 kg. The combined session total is 1,880 kg; a single average-load entry can hide those differences.
Keep comparisons consistent
- Switching between per-dumbbell and combined-dumbbell load.
- Entering planned reps when fewer reps were actually completed.
- Applying the weekly multiplier to sessions with different exercise blocks.
- Comparing machine-stack numbers, barbell lifts and bodyweight exercises as if equal totals meant equal training stress.
- Increasing tonnage while range of motion, technique or recovery deteriorates.
What volume load leaves out
Sets × reps × load is useful for checking changes in the same exercise under similar conditions. It does not account for range of motion, movement distance, tempo, assistance, proximity to failure or which muscles do the work. The displayed kg total is repeated external load; it is not mechanical work in joules.
Bodyweight and assisted movements do not have a reliable external-load equivalent in this simple form. Keep those records separately or use a consistent documented convention. Training progress also needs performance, technique and recovery context; a larger weekly number is not automatically a better programme.
Training Volume Calculator FAQs
What if each set has a different load or rep count?
Calculate each group of identical sets separately and add their session totals. The form assumes the same reps and load for every set in one calculation.
Do I enter one dumbbell or both?
Use one consistent convention. For a movement performed with two dumbbells together, you can enter their combined load and record that choice. Do not switch conventions when comparing sessions.
Does weekly volume assume identical sessions?
Yes. It multiplies the entered exercise block by the number of sessions. Calculate separate blocks for different training days.
Does more volume load prove more muscle growth?
No. This arithmetic does not measure muscle growth, effort, technique or recovery. It is one training-log measure.
Use tonnage as one training-log measure
Keep the exercise, load convention and rep quality consistent. Use the session and weekly totals to understand what changed, then assess progress alongside performance and recovery.
