Calculate total training volume (tonnage) — sets × reps × weight — for a single exercise or a full session. Use simple mode for uniform sets, or multi-set mode for ramped warm-ups and mixed loading.
Training volume — often called tonnage — is the total weight lifted for an exercise or session, calculated as sets × reps × weight. For example, 4 sets of 8 reps at 60 kg produces a training volume of 1,920 kg for that exercise. Lifters track volume over time to monitor overall workload, manage fatigue, and apply progressive overload across a training block.
| Set | Reps | Weight | Volume |

Training volume for a single set is simply the weight moved, repeated for every rep. For a block of identical sets, multiply straight through: sets × reps × weight. When sets differ — a lighter warm-up ramp followed by heavier work sets, for instance — total volume is the sum of (reps × weight) for each individual set rather than a single multiplication.
Volume can be tracked at whatever level is useful — per set, per exercise, or across a whole session. Adding up the volume for every exercise in a workout gives a session total, which is a convenient single number for comparing how demanding one training day was against another.
Progressive overload — gradually increasing the demand placed on a muscle over time — is one of the core drivers of strength and muscle adaptation. Total volume is one lever for applying it: alongside adding weight or improving technique, a lifter can add sets or reps within a training block to increase workload over successive weeks.
Many lifters log volume per session and then review it on a weekly or per-block basis, watching whether the trend is rising, holding steady, or dropping. Volume typically rises gradually across the productive weeks of a training block and is deliberately reduced during a lighter deload week to allow recovery, before the next block begins. How much volume to add, and when to pull back, depends heavily on individual recovery capacity, training age, nutrition, sleep, and the specific exercises involved — general volume-tracking principles like these are best applied within a structured program rather than as a fixed formula.
Volume is a useful, easy-to-calculate workload indicator, but it has real limits. It counts weight moved without capturing how hard each set actually felt — a set taken to failure and a set with several reps in reserve can produce identical tonnage despite very different training stimulus. It also doesn't distinguish between exercises with very different demands (a heavy deadlift versus a light isolation curl can rack up similar raw numbers) and isn't a fair way to compare different lifters, since body size, leverages, and technique all affect the weight someone can move. Volume is most useful as a relative, within-person trend metric — tracking your own numbers on the same exercise over time — rather than as an absolute measure of effort or a way to rank lifters against each other.
What is training volume in weightlifting?
Training volume, often called tonnage, is the total amount of weight lifted across a workout, exercise, or training period. It's typically calculated as sets × reps × weight lifted per rep, summed across every set performed. Volume is a simple way to quantify overall workload independent of how heavy each individual lift felt.
How is training volume calculated?
For sets performed at the same weight and reps, volume equals sets × reps × weight. For sessions with different weights across sets — such as a warm-up ramp followed by heavier work sets — volume is the sum of (reps × weight) for each individual set. This calculator supports both approaches: a simple mode for uniform sets and a multi-set mode for mixed loading.
How much weekly training volume should I do?
There's no single number that suits every lifter — appropriate volume depends on training experience, recovery capacity, exercise selection, nutrition, sleep, and overall programming goals. Most structured programs increase volume gradually across a training block and periodically reduce it to allow recovery. If you're unsure how much volume is right for you, a qualified strength coach or accredited exercise physiologist can help design a program suited to your individual circumstances.
Does training volume matter more than intensity?
Neither volume nor intensity (the weight relative to your maximum) tells the full story on its own — both contribute to training outcomes, along with proximity to failure, exercise selection, and consistency over time. Volume is useful for tracking overall workload and trends, while intensity and effort (such as RPE) capture how hard each set actually was. Well-designed programs typically manage both together rather than prioritising one exclusively.
Can I use training volume to compare different exercises or lifters?
Not reliably. Volume is most meaningful as a relative, within-person trend metric — comparing your own volume on the same exercise over time. Comparing raw tonnage between different exercises (e.g. squats vs bicep curls) or between different lifters ignores differences in leverages, body weight, technique, and range of motion, so such comparisons are not a fair or useful measure of effort or progress.
What's the difference between simple mode and multi-set mode in this calculator?
Simple mode is for sessions where every set uses the same weight and rep count — you enter sets, reps and weight once, and the calculator multiplies them together. Multi-set mode is for sessions where sets vary, such as a ramping warm-up followed by heavier top sets; you enter each set's reps and weight individually, and the calculator sums the volume across every row you add.
How often should I track my training volume?
Many lifters log volume every session and review weekly or per-training-block totals to see whether volume is trending up, staying flat, or dropping. Reviewing over a full week or training block usually gives a clearer picture than looking at any single session in isolation, since day-to-day volume naturally varies with programming.
