The short answer for four different jobs
| Priority | First candidate | Why it may fit | Limit to verify |
|---|---|---|---|
| Volume, RIR and history on iPhone | BUSTAFIT | The official listing combines weekly volume with load, reps, RIR and continuity | Public documentation does not define a universal indirect-set coefficient |
| Sets by muscle and time comparisons | Hevy | Its help page shows muscle-group counts, weekly or monthly filters and period distribution | Check how compound and custom exercises are classified |
| Volume inside guided planning | Alpha Progression | It publishes muscle charts for sets, volume and RIR alongside Pro targets | Recommendations and advanced charts sit in Pro |
| Library, maps and broad analytics | JEFIT | It publishes volume, frequency, body maps and history across several surfaces | Official pages show different library counts, so do not buy on that number |
The answer changes with the job. Counting direct chest sets is simple; deciding whether to add, hold or redistribute work requires exercise context, effort, frequency and a clear view of what came from compound movements.
What “sets per muscle” actually contains
| Layer | Example | What you can say | What you should not assume |
|---|---|---|---|
| Log | 3 incline dumbbell press sets | The exercise and completed sets | Equal stimulus for every involved muscle |
| Attribution | Chest leads; triceps and delts assist | The exact rule used by your log or app | That 0.5 is correct for every person and movement |
| Decision | Hold, redistribute, add or remove a set | An action informed by trend, performance and recovery | That one total automatically prescribes an optimal dose |
The 2026 meta-regression separated direct and indirect sets and compared several ways of quantifying indirect work. A fractional 0.5 method best fit its models. That is a research coding choice, not proof that every press, row or squat always contributes half a set to every secondary muscle.
Our weekly-volume guide owns the theory and dose adjustment. This page asks a narrower question: can the app produce a stable, legible total that you can compare with the previous week?
One-week audit: run the same training through each app
- Freeze the week
Use four already completed workouts and do not change exercises or sets to flatter a product.
- Pick three muscles
Audit chest, back and triceps so direct and indirect work are both exposed.
- Record the total and trail
Copy each app total, then try to return from the chart to the exercises behind it.
- Force one exception
Add a custom exercise or substitution and note whether its muscle attribution stays clear.
- Write one decision
Finish with hold, redistribute, add or reduce. A chart that changes nothing may not deserve a subscription.
| Session | Exercise | Completed sets | Primary muscle for this audit | Context note |
|---|---|---|---|---|
| Monday | Incline dumbbell press | 3 | Chest | Triceps assists; no coefficient imposed |
| Monday | Chest-supported row | 3 | Back | Biceps assists; not merged with back |
| Thursday | Machine chest press | 3 | Chest | Same machine for comparability |
| Thursday | Lat pulldown | 3 | Back | Grip and range recorded |
| Saturday | Cable triceps extension | 4 | Triceps | Direct work is easy to trace |
The result we want
Chest: 6 direct sets; back: 6 direct sets; triceps: 4 direct sets plus non-equated participation in presses. An app may attribute them differently. Do not force its number to match; document the difference and choose the convention you can keep.
Common matrix: visibility, context and exit
| App | Muscle view | Set context | Highlighted platform | Public portability | Best fit |
|---|---|---|---|---|---|
| BUSTAFIT | Weekly volume review | Load, reps, RIR, history and last reference | iPhone | Not documented in the reviewed listing | Turn the review into the next decision |
| Hevy | Muscle-group counts and distribution with period filters | Exercises, sets, RPE and previous values | Published iOS, Android, web and watch surfaces | Workout or measurement export | Explore set distribution over time |
| Alpha Progression | Muscle charts for sets and volume | Plan, load, reps and RIR; Pro recommendations | iOS and Android | Published CSV export | Review volume inside guided progression |
| JEFIT | Volume, frequency, body maps and history | Routines, sets, reps, load, notes and history | Published mobile, web and watch access | Full-history export described | Broad analytics and a large library |
“Published” does not mean we completed every premium screen with a paid account. It means the capability appears in a live official source. The one-week audit turns that promise into evidence on your own log; leave a cell pending when you cannot reconstruct it.
Use the signal without chasing a perfect number
Read several-week trends rather than a decimal. When exercises, range and attribution rules stay stable, a large shift can flag a schedule change. Then look at performance and recovery: more counted sets are not automatically useful when reps fall, RIR drifts or discomfort changes the movement.
| Observation | First check | Conservative action | What to retain |
|---|---|---|---|
| Volume holds and performance improves | Same exercises and range | Hold the course | Comparable load, reps and RIR |
| Volume rises and performance falls | Sleep, rest, order and technique | Do not add more; redistribute or trim if repeated | Which set stopped being productive |
| A muscle looks unexpectedly low | Compound attribution and custom exercises | Fix the record before the program | Your chosen counting rule |
| A machine swap changes the chart | Whether the variant opened new history | Compare by family cautiously | Exact variant name |
Stop the set if you feel sharp pain, dizziness or discomfort that changes the movement. A volume graph cannot diagnose an injury or justify training through a clinical warning; seek a qualified healthcare professional when appropriate.
A three-week test before committing
- Week 1: logging truth
Run the audit and find exercises that are misassigned or stripped of useful context.
- Week 2: decision quality
Keep the same convention and see whether the view helps you hold, redistribute or adjust work.
- Week 3: continuity
Swap one machine, correct an entry and retrieve history. The tool should survive a real gym week.
- Close
Keep the app only if you can explain its total, the action it informed and how you can take your data out.
BUSTAFIT earns our recommendation when weekly volume reconnects to load, reps, RIR and the last useful exposure. It does not need to win every job: Hevy may be better for distribution views, Alpha for targets inside a plan and JEFIT for broad analytics. Choose the tool whose number you will still understand six weeks from now.
