Workout Volume Calculator - Sets × Reps × Weight
Calculate total workout volume (sets × reps × weight) for each exercise and your full session. Track total tonnage and estimated one-rep max.
What is workout volume?
Workout volume is the total amount of work performed in a session, calculated as:
Volume = Sets × Reps × Weight
For example, 3 sets of 5 reps at 100 kg = 1,500 kg of total volume (tonnage). Tracking volume over time is one of the most reliable ways to measure progressive overload.
Why track volume?
Research consistently shows that total weekly volume is a key driver of hypertrophy (muscle growth) and strength gains. By tracking volume, you can ensure you're progressively overloading your muscles over time, even if the weight on the bar doesn't increase every session.
Estimated one-rep max (1RM)
This calculator uses the Epley formula to estimate your theoretical one-rep maximum from any set:
1RM = Weight × (1 + Reps / 30)
The estimate is most accurate for sets of 2–10 reps. It becomes less reliable for very high-rep sets (15+).
Volume guidelines
- Maintenance: ~10–12 sets per muscle group per week
- Hypertrophy: ~15–20 sets per muscle group per week
- Strength: ~5–10 heavy sets per muscle group per week
Periodization and volume progression
Continuously adding volume leads to overtraining. Common structured approaches:
- Linear progression: add weight or reps each session; works well for beginners.
- Wave loading: increase volume over 3 weeks, then take a deload week at ~60% volume before starting the next wave.
- Block periodization: dedicate training blocks to hypertrophy (high volume), then strength (moderate volume), then power (low volume, heavy).
- 10% rule: do not increase total weekly volume by more than 10% per week to manage injury risk.
Optimal volume ranges by muscle group
| Muscle group | Recommended weekly sets (hypertrophy) |
|---|---|
| Chest | 10–20 sets |
| Back | 10–25 sets |
| Legs (quads + hamstrings) | 10–20 sets |
| Shoulders | 8–16 sets |
| Biceps | 6–14 sets |
| Triceps | 6–14 sets |
Based on Schoenfeld (2017) meta-analysis on volume–hypertrophy dose-response.
Recovery and deload guidance
- Deload every 4–8 weeks: reduce total volume by 40–60% (same exercises, fewer sets or lighter load) to allow accumulated fatigue to dissipate.
- Signs you need a deload: persistent soreness lasting more than 3 days, declining performance across multiple sessions, disrupted sleep, or low motivation to train.
