Fractional set contribution
Compound lifts can distribute work across muscles instead of pretending every involved muscle received a full set.
Muscle volume tracker
A muscle volume tracker that keeps the rest of training visible.
Totality turns completed sets into per-muscle volume estimates, then keeps volume connected to effort, frequency, intensity, PRs, and exercise selection.

What it helps with
A focused workflow, backed by training context.
Weekly context
Average weekly muscle volume helps lifters compare training blocks and spot undertrained areas.
Not volume alone
Read volume alongside RIR, RPE, intensity, PRs, estimated 1RM, and notes before changing a plan.
Decision signals
What to look for before choosing an app.
| Need | Why it matters | How Totality handles it |
|---|---|---|
| Muscle-level distribution | Set count by exercise can hide which muscles actually received useful work. | Uses exercise-level muscle distribution to estimate per-muscle volume. |
| Frequency | The same weekly volume can feel different when split across sessions or crammed into one day. | Pairs volume with weekly training context and calendar views. |
| Recovery context | More volume is not automatically better if intensity and fatigue are unmanaged. | Keeps volume near effort, intensity, PRs, habits, and notes. |
FAQ
Questions people ask before switching.
What is a muscle volume tracker?
A muscle volume tracker estimates how much work each muscle received across workouts, usually by counting sets or fractional set contribution.
Why is fractional muscle volume useful?
Fractional volume is useful because compound lifts train multiple muscles with different levels of contribution.
Should I make decisions from volume alone?
No. Volume is useful, but it should be read with effort, intensity, frequency, exercise selection, recovery, and performance trends.
