Transparent Adjudicator's Statement
Summary of Claim
Greiner submitted a claim that he had completed 222 L-sit muscle-ups within one hour. The first completed repetition appeared at approximately 06:49 on the submitted video timeline, and the 222nd repetition was completed at approximately 1:03:00, producing a verified active duration of 56 minutes and 10 seconds.
Evidence Submitted
The evidence package included a continuous video recording of the attempt showing the athlete, exercise bar and performance area throughout the relevant period.
The recording contained visible evidence of the repeated exercise movements, rest intervals and completion of the final repetition. The submitted file also included embedded metadata identifying the recording date as 9 July 2026.
Greiner additionally provided a written account describing the purpose of the attempt, his preparation, the significance of the 222-repetition target and the circumstances surrounding the performance.
Comparative and Cross-Archive Benchmark Review
Atlas World Records cross-referenced the publicly available records maintained by all major world record organizations, together with other publicly reported and independently discoverable claims involving L-sit muscle-ups and closely related calisthenics disciplines.
The strongest directly comparable published benchmark identified was 201 L-sit muscle-ups completed within one hour by Alejandro Soler Tarí in La Marina, Alicante, Spain, on 12 October 2025.
No credible publicly documented performance exceeding 201 repetitions was identified during the cross-archive review conducted in connection with this adjudication.
Verification Methodology
The submitted video was reviewed through three independent counting passes.
Reviewers identified the beginning and completion of each attempted repetition, maintained cumulative counts across all working sets and compared the results of the separate reviews. Particular attention was given to the visible performance of the L-sit muscle-up movement, continuity of the recording, repetition sequencing and the elapsed time between the first and final completed repetitions.
The timeline was independently checked to establish that the performance fell within the required one-hour period. The first verified repetition was identified at approximately 06:49, and the final repetition was completed at approximately 1:03:00.
The difference between those two timeline positions was calculated as 56 minutes and 10 seconds.
Adjudication Findings
The adjudication review confirmed a total of 222 completed L-sit muscle-ups.
The recording was continuous throughout the relevant performance period, and no interruption, edit or time discontinuity was identified that would invalidate the submitted sequence.
All 222 repetitions were completed within 56 minutes and 10 seconds, placing the full verified result within the one-hour limitation.
Greiner’s result exceeded the controlling published benchmark of 201 repetitions by 21.
Conclusion
Atlas World Records concludes that Garrett Greiner successfully completed 222 L-sit muscle-ups within one hour in Sioux City, Iowa, United States, on 9 July 2026.
The claim satisfies the applicable requirements for recognition as the world record for the Most L-Sit Muscle-Ups in One Hour.
