Overview

• Quadrobics features crawling, bounding and balancing on all fours in eye-catching social media videos that frame the practice as primal movement.
• Guinness World Records for the 100 meters on all fours have progressed from Kenichi Ito in 2008 to Collin McClure in 2022, with Japan’s Ryusei Yonee lowering the mark to 14.55 seconds in 2025.
• Researchers note limited evidence for improvements in balance, flexibility and core stability but no proof it surpasses mainstream exercise for strength or long-term health.
• Experts advise starting slowly because the moves load the hands, wrists, elbows and shoulders, and body-weight resistance curbs strength gains compared with lifting and delivers less cardiovascular benefit than running.
• Much of the online output is tied to the therian community—distinct from the furry fandom—and the trend has drawn official reaction in parts of the former Soviet region, including an Uzbek warning to parents and denunciations by Russian politicians.
