How this calculator works
Session volume load equals sets × repetitions × load. Weekly volume multiplies session volume by planned weekly frequency.
How to use your result
Record volume for one exercise, then compare it with the same exercise in a later session. Example: four sets of eight repetitions with 80 kg equals 2,560 kg of session volume. If your previous comparable session was 2,400 kg, workload increased by 6.7%.
What useful progress looks like
A small increase can come from one extra repetition, a modest weight increase, or one additional set. Avoid increasing all three at once. For muscle gain, also track hard working sets, proximity to failure, technique, and recovery. For strength, load and rep quality often matter more than total tonnage.
Compare like with like
Volume load becomes misleading when exercise, range of motion, machine, tempo, or technique changes. Do not compare leg-press tonnage directly with squat tonnage. Treat each exercise as its own trend.
Important limitation
Calculator results are estimates. Pregnancy, eating disorders, medical conditions, injuries, or concerning symptoms require qualified professional guidance.
