Why Range of Motion Notes Matter

Range of motion is one of those things everyone says matters, right up until the weight gets heavy and suddenly the rep becomes more of a rumor. That is not a moral failure. It is just a reason your training log should have context.

If last month you squatted 225 deep and this month you squatted 245 halfway down while your knees filed a noise complaint, those are not cleanly comparable sets. The number went up. The lift changed.

The problem with raw PRs

A training log that only stores load and reps has to assume every rep was performed the same way. That assumption is convenient, and also occasionally nonsense. Bench depth changes. Squat depth changes. Pull-up range changes. Machine setup changes. The app cannot know that unless you tell it.

That does not mean every set needs a courtroom transcript. It means the outliers should be marked. Full range, partial range, assisted range, shortened range, paused reps, controlled eccentrics: these notes keep your future comparisons honest.

The goal is not to shame partial reps. The goal is to stop pretending every rep was the same species.

Partial reps are not automatically bad

Partial range work can be useful. Overloads, top-half presses, lengthened partials, machine finishers, injury-aware modifications, and sport-specific work can all have a place. The issue is not doing a partial. The issue is logging it like a normal full-range set and then acting shocked when your trend chart gets weird.

A good log does not judge the set. It labels the set.

When to note range of motion

• The rep standard changed. Your squat depth, bench touch, pull-up height, or machine setup was meaningfully different.
• You used a deliberate partial. Top-half, bottom-half, lengthened partial, assisted partial, or shortened range work.
• You changed tempo or pauses. A paused bench and a bounced bench are not the same data point.
• You modified around discomfort. No diagnosis needed. Just note that the movement was adjusted.

How OpenSet thinks about it

OpenSet tracks range and rep style because serious progress is not just heavier weight. It is heavier weight under comparable conditions. When the conditions change, the log should know.

That is the whole point: fewer fake PRs, cleaner history, and less mental archaeology six weeks later when you are trying to remember whether that great set was actually great or just suspiciously short.
