Josef Šálek
체코
Czech athlete Josef Salek held the plank position for 9 hours, 35 minutes, and 6 seconds (34,506 seconds) on May 18, 2024, in Prague, setting a world record. The plank -- supporting the body on forearms and toes -- tests core strength and mental endurance to their absolute limits. This record edged out the previous mark of 9 hours, 30 minutes, and 1 second held by Australia's Daniel Scali. Long-duration planking also demands careful joint and breathing management.
