On 10 May 2026, Bulgarian endurance athlete Stanislav Zlatarev established the inaugural benchmark for Most Traditional Sit-Ups Completed in 12 Hours (Bent-Knee Definition). The achievement was undertaken as a charitable fundraising and awareness initiative benefiting organizations supporting children's health and medical care.
Transparent Adjudicator's Statement
Summary of Claim
The claimant asserted that he completed the greatest number of traditional sit-ups under a defined movement standard requiring bent knees, affixed feet, and consistent repetition mechanics during a continuous endurance attempt conducted within a 12-hour category framework.
Evidence Submitted
Continuous unedited video documentation of the attempt
Automated repetition counting records
Post-event technical review documentation
Timing overlays embedded within the primary video record
Comparative and Cross-Archive Benchmark Review
Atlas World Records conducted a comparative review of publicly available records and benchmarks published across major world record organizations, endurance sports archives, athletic record databases, and historical fitness-performance repositories.
The review identified numerous sit-up records measured under differing movement standards, durations, and counting methodologies. No prior benchmark was located that precisely matched the bent-knee, feet-affixed, traditional sit-up definition utilized for this category. Accordingly, Atlas determined that this category represented a distinct and previously uncodified record classification.
Verification Methodology
Atlas reviewed continuous video evidence documenting the attempt from commencement through termination. The movement standard required knees maintained in a bent position throughout the attempt, feet affixed, and each repetition completed according to the prescribed range-of-motion requirements.
Automated counting data was reviewed alongside video evidence and technical documentation. Additional repetitions identified during technical review were incorporated into the final verified total where supported by the evidentiary record. Timing data embedded within the video was used to verify the duration and continuity of the attempt.
Adjudication Findings
Atlas determined that the claimant successfully completed 7,337 traditional sit-ups under the prescribed movement standard.
The evidentiary package demonstrated continuous performance, compliance with category requirements, and sufficient documentation to verify the claimed result. During the attempt, the claimant sustained a significant hip-flexor injury yet continued the effort until the injury rendered further participation unsafe.
Conclusion
Following review of the submitted evidence and application of Atlas Verification Protocol standards, Atlas World Records recognizes Stanislav Zlatarev as the inaugural world record holder for:
MOST TRADITIONAL SIT-UPS COMPLETED IN 12 HOURS (BENT-KNEE DEFINITION)
with a verified total of 7,337 traditional sit-ups achieved on 10 May 2026 in Varna, Bulgaria.
