A viral fitness trend called “quadrobics” involves people moving on all fours through bear crawls, leopard walks, and bounds. The practice gained attention after Japanese sprinter Kenichi Ito set a Guinness World Record in 2008 by running 100 meters on all fours. American Collin McClure later clocked 15.66 seconds in 2022, while Japanese runner Ryusei Yonee broke the record this year with 14.55 seconds. Yonee said he studied animal movement from childhood and trained by observing dogs, cats, and monkeys. Research suggests quadrupedal movement can improve balance, flexibility, and core stability while providing aerobic benefits. However, experts warn it’s limited for building strength compared to weight lifting and poses injury risks to wrists and shoulders. (Story URL)
