Why is a muscle group missing from the volume bars?

It means no logged sets in the last 7 days trained that muscle group — the bars only reflect the rolling week, not your full history.

Should I worry about one bad session on the chart?

Not usually — look at the trend across several sessions and weeks rather than reacting to a single low number.

Why didn’t a heavy set get flagged as a PR?

A set is only flagged as a PR if it beats your previous best for that exact exercise — matching, not beating, your best won’t trigger the tag.

How to Read Your Workout Analytics

Last updated 26 July 2026

IRONSLOG's analytics screen has four signals worth reading every week: weekly training volume ranked by muscle group, a per-exercise estimated 1RM or top-set chart, auto-flagged PRs, and plan adherence. Together they answer whether your training is balanced, trending up, and actually happening as planned.

What do the muscle-volume bars actually mean?

Each bar ranks a muscle group by tonnage (weight × reps) from your logged sets over the last 7 days, longest bar first. A muscle group with a consistently short bar week after week is getting comparatively little direct work — useful to notice before it shows up as a lagging body part or a weak point in a lift.

How should I read the per-exercise chart?

Look at the trend across weeks, not any single session. A single lower number after a hard week or a missed rest day isn't a regression; a flat line across four or more sessions and several weeks is what the deload note is built to catch. Toggle between top-set and estimated 1RM depending on whether your rep ranges stay consistent.

What’s a "good" adherence percentage?

There isn’t a universal number — adherence just tracks the share of scheduled sessions actually completed, and it’s most useful compared against your own history. A dropping trend is worth investigating (is the plan too ambitious for your schedule?) more than a single missed week is worth worrying about.

Reading your analytics well takes six steps, in this order:

Open the analytics/progress screen. Both muscle-volume bars and the per-exercise chart live on the same screen.
Scan the muscle-volume bars first. Look for any muscle group with a consistently short bar over several weeks.
Pick an exercise and read its chart. Toggle top-set vs estimated 1RM and look at the multi-week trend, not one session.
Note any PR tags. These are auto-flagged wherever a logged set beat your previous best.
Check your adherence percentage. Compare it against your own recent history rather than a fixed target.
Act on a deload note if one appears. It only shows up when a lift is genuinely stalled across several sessions and weeks.

Key takeaways

Muscle-volume bars rank the last 7 days of training by muscle group, longest bar first.
Read the per-exercise chart as a multi-week trend, not a single session.
PRs are flagged automatically wherever they happen — no need to track them by hand.
Adherence is most useful compared against your own history, not a fixed benchmark.
