Progressive overload can come from load, reps, sets, or quality—not volume alone. Adjust with a coach if you are new or returning from injury.
Classic definition
Total load moved
A simple way to compare sessions when the prescription is uniform.
Same lift
Rough total
Useful when bench or squat days repeat with similar sets and reps.
Hard vs easy sets
Log separately
Heavy singles and light back-off work differ even at equal tonnage.
Load, reps, tempo
Many levers
You can progress by quality and bar speed—not only more plates.
Caps gains
Match volume
High tonnage without recovery is a recipe for stagnation or injury.

Run the calculator separately for squat, press, and pull blocks if loads differ.
Default: 4×8 @ 185 lb, 3×/week → about 5920 lb per session and 17760 lb/week in this model.
We multiply sets, reps per set, and weight to produce session tonnage in your chosen unit, then convert the same physical work to kilograms and pounds of total load for easy comparison. If you add sessions per week, we scale the per-session number for a rough weekly total. Browse more fitness & lifestyle strength tools on the hub.
volume (per session) = sets × reps × weight
weekly volume ≈ volume × sessions per week (when provided)
