What weekly volume means here
This guide uses volume as working sets per muscle group per week. It is a practical dose measure, not a complete description of stimulus: exercise choice, proximity to failure, range of motion, load, frequency and execution all change what one set represents.
| Type | Example | How to record it |
|---|---|---|
| Direct | Leg extension for quadriceps | 1 direct set |
| Primary multi-joint | Squat for quadriceps | 1 direct set when quads are a clear target |
| Indirect | Pressing for triceps | Separate or use a consistent coefficient |
| Warm-up | Ramp-up set | Do not count as a working set |
Build a reproducible weekly ledger
| Exercise | Direct | Indirect | Coefficient | Editorial total | Typical RIR |
|---|---|---|---|---|---|
| Bench press | Chest 3 | Triceps 3 | 0.5 for triceps | Chest 3 · triceps 1.5 | 2–3 |
| Triceps extension | Triceps 3 | — | — | Triceps 3 | 1–2 |
| Row | Back 3 | Biceps 3 | 0.5 for biceps | Back 3 · biceps 1.5 | 2–3 |
The example's 0.5 is not a demonstrated conversion. It is an editorial convention that avoids treating indirect work as either zero or universally equal to a direct set. Choose another rule or keep separate columns; write the criterion down and do not change it mid-comparison.
- Close each workout
Log completed sets, exercise and RIR instead of reconstructing volume at month end.
- Group by muscle
Sum direct sets and preserve indirect work under the same rule.
- Add adherence
Separate planned volume from work actually completed.
- Compare the trend
Inspect performance, skipped repetitions and recovery before adjusting.
Why ten sets is not a magic number
Earlier meta-analyses observed more growth with higher weekly volumes in particular study groups, and recent models describe a dose-response relationship with diminishing returns. The approximate ten-set reference comes from study averages and categories; it is not a threshold everyone must cross or a guaranteed optimum.
- Additional sets may provide progressively less benefit as dose rises.
- Experience, muscle group, exercise and proximity to failure change the response.
- A program can only be evaluated when the person completes it reasonably well.
- Adding volume that degrades every set can reduce session quality and data quality.
Hold, add or reduce
| Pattern across several weeks | Reading | Editorial action |
|---|---|---|
| Performance improves and dose is completed | Current volume is productive | Hold |
| Performance is stable, adherence is good and capacity exists | A small test may fit | Add one or two total sets for the muscle and observe |
| Performance declines, workouts are skipped or quality degrades | Dose may exceed what is executable | Reduce or redistribute before adding |
| Exercise, RIR or frequency changed | Several variables are new | Hold volume until comparisons return |
Where BUSTAFIT fits
BUSTAFIT records sets, load, repetitions, RIR and history on iPhone, giving you the completed work needed to rebuild a week without selective memory. We recommend using it as the source for work actually done while keeping your indirect-set coefficient visible in the review. The app does not document automatic calculation of optimal volume or prescribe how many sets to add.
Ledger close
Quadriceps: 10 direct sets planned, 9 completed; stable squat performance and improved leg extension; no repeated decline. Output: hold for another week. The number describes dose; the trend determines whether it should change.
