What a camera can see in a ring muscle-up
The rubric scores extension on the rings at the top, how deep the pull went, and the time the concentric phase took. The thresholds differ from the bar version in two places: the lockout band is a little more permissive, and the transition is allowed to be slower, because a ring transition genuinely takes longer than a bar one. Treating them identically would have penalised the harder movement for being harder.
How ScoreRep scores a ring muscle-up
The rubric declares 4 scored criteria. The strongest single camera angle is the front 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.
| Criterion | Points | Measured from the athlete’s pose | Full marks when |
|---|---|---|---|
| Full extension on the rings | 35 | largest elbow angle in the rep | 165° or more |
| Pull quality | 25 | smallest elbow angle in the rep | 45° or less |
| Explosiveness | 25 | time taken by the lifting phase | 1s or less |
| Consistency across the set | 15 | drop in rep speed between the fastest and the slowest rep | 15% or less |
Does this ring muscle-up rep count?
ScoreRep answers that in two separate steps. First, the clip has to read as a ring muscle-up 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 ring muscle-up rubric, the same file the scoring engine runs.
- Compare the ring muscle-up standard with the other 29 movements on the movement standards page.
- How the rep counter decides between a valid rep and a no-rep, station by station.
| Reading | Has to be | Otherwise rejected because |
|---|---|---|
| Vertical travel of the shoulders across the rep | 0.08 or more | the shoulders do not travel far enough vertically |
| Whether the hands finish above the shoulders | no | the rep does not finish in support with the shoulders above the hands, so the muscle-up is incomplete |
| Elbow angle in the finish position | 150° or more | the elbows are not locked out at the finish, so the press-out is incomplete |
| Smallest elbow angle in the rep | 70° or less | the elbows do not close far enough, so there is no transition over the rings |
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
If ring muscle-up scores sit consistently below bar muscle-up scores for the same athlete, the transition time is usually the reason rather than the lockout. That is expected and not something to correct directly. The criterion that repays attention is pull depth: on rings it degrades quietly, because the rings drift apart rather than the athlete visibly failing.
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.
