Toes-to-bar analysis: hip flexion is the movement, so it carries most of the score.

Toes-to-bar is measured at the hip, which is the one joint that cannot be faked by a bigger swing.

What a camera can see in a toes-to-bar

The rubric scores the smallest hip angle reached at the top of the rep, which is how far the athlete actually folded, along with torso control and cadence. Filming from the side or an oblique angle is necessary for the hip measurement; the front hides the fold almost completely. The identity gate also watches the elbows: arms bending past a threshold means the athlete is pulling into a muscle-up rather than folding into toes-to-bar.

How ScoreRep scores a toes-to-bar

The rubric declares 4 scored criteria. The strongest single camera angle is the left side view. Every criterion below is available from that angle.

The score is the points earned divided by the points the recorded angle could support, so a clip filmed from a limited angle is never quietly marked down for what the camera could not see. At least 60% of the applicable weight has to be measured before a result is ranked at all.

Criteria that depend on the camera angle

These criteria are excluded, not estimated, when the recorded angle cannot support them. That is why the same set filmed twice from different positions can produce two valid scores out of two different totals.

  • Range, feet to the bar — needs a left side, right side, left oblique and right oblique view.
  • Body control — needs a left side, right side, left oblique and right oblique view.

Does this toes-to-bar rep count?

ScoreRep answers that in two separate steps. First, the clip has to read as a toes-to-bar at all: every check in the table below has to pass, and a reading the camera could not take counts as a fail, never as a pass. A clip that fails is returned unranked with the reason attached, rather than scored low against the wrong rubric, and no template can override a failed check.

Second, the scoring criteria award points. Falling short of a full-marks threshold costs points, not the rep. Every number here is read from version 2 of the toes-to-bar rubric, the same file the scoring engine runs.

What the recording has to contain

Eligibility decides whether a result can enter a leaderboard. Failing it does not block the feedback — the clip is still scored and returned, but marked unranked with the reason attached, so a bad camera position never silently becomes a bad score.

  • A pose has to be detected in at least 50% of the frames.
  • The camera angle has to be one of: front, back, left side, right side, left oblique and right oblique.
  • At least 1 complete repetition has to be detected.

What is deliberately not scored

Identity, repetition counting, eligibility and the score are derived only from the athlete’s pose. Measurements that come from tracking an external object — the path of a barbell, for example — are drawn on the review overlay but are deliberately outside the scoring contract, so they never affect the number.

Reading the result

Cadence and hip flexion usually trade off against each other in a long set. Athletes keep the rhythm and stop reaching the bar, so the hip score falls while the cadence score holds. Reading them together identifies the rep where the set stopped counting for most standards, which is more actionable than the total. The consistency criterion covers the same ground over the whole set.

A technique score is educational feedback about visible movement. It cannot tell you whether a load is safe for your joints, whether pain means something, or whether a programme suits you. Those judgements need a coach or clinician who knows your history.

Questions

What athletes usually ask

Does ScoreRep check that the feet touched the bar?

No. It measures hip flexion, which is what determines how close the feet get. Contact itself is not visible reliably enough to score.

Which camera angle is required?

Side or oblique. The hip criterion is excluded from a front or back view because the fold cannot be measured from there.

How is this told apart from a muscle-up?

By the elbows. If they bend past the threshold, the identity gate treats the rep as a muscle-up and does not score it here.
