Volume Adherence

Also known as: Rep Compliance, Volume Match

How closely your actual rep volume matched the planned prescription, expressed as a percentage. 100% means exact match; above means you did more, below means less.

Formula

Volume Adherence = (actual total reps / target total reps) x 100

Example

Planned: 120 reps. Actual: 108 reps. Volume adherence = 90%.

How Afitpilot Uses This

Volume adherence is tracked alongside load adherence and effort delta to give a complete picture of session execution. The trend over 6 sessions is computed via linear regression — "improving" (slope > 0.02), "declining" (slope < -0.02), or "stable".

Volume adherence — what the numbers mean

Who / Context	Value	Note
< 85%	Under-dosing	Leaving stimulus on the table
85-110%	Sweet spot	On prescription or slightly above
> 110% consistently	Over-shooting	Possible junk volume or plan too conservative
Active aging (60+)	Typically 90-100%	Following the plan closely = underrated strength

Known Limitations

•Exercises with non-normalizable reps (AMRAP, time-based, "to failure") are excluded from both planned and actual totals, which can reduce the coverage and meaningfulness of this metric for conditioning-heavy sessions.

Science Context

Volume adherence reflects the dose-response relationship in training. Insufficient volume may limit adaptations, while chronically exceeding prescribed volume without corresponding recovery may increase injury risk.
