Tengrinews.kz – A Japanese man, Ryusei Yone, has entered the Guinness World Records by running 100 meters in 14.55 seconds — on all fours.
The Guinness World Records press service recognized the achievement of Ryusei Yone, who completed the 100-meter dash in 14.55 seconds.
At first glance, this might seem like an ordinary sprint — but the method changes everything: Yone ran the distance using all four limbs.
According to Yone himself, to perfect his technique, he observed various animals, including domestic dogs, cats, and monkeys. He also consulted with sports coaches and sports medicine specialists.
His record attempt took place on September 24 in Japan.

Guinness Record Holder — a Quadruped Runner?
Yone’s behavior before and after the attempt resembles the growing trend of “quadrupeding” (also known as “quadrubing” or “quadrobics”) — a physical activity where people move on all fours, imitating animals like dogs, cats, or monkeys.
Participants, known as “quadrobbers”, often wear masks, ears, or tails to fully embody the animal role, performing exercises like running, jumping, or crawling on hands and feet.
This movement blends fitness, parkour, and self-expression, helping to build strength, improve coordination, and foster a sense of connection with the animal world. In recent years, quadrobics has become a subculture, especially among youth aged 7–14, with viral videos on TikTok and Instagram gaining millions of views.
The Origins of Quadrobics
The roots of quadrupedal movement trace back to the 2000s. Its unofficial founder is Japanese sprinter Kenichi Ito, who was mocked as a child for his appearance and nicknamed "monkey".
Turning the insult into inspiration, Ito began training on all fours. In 2008, he set a world record by running 100 meters on all fours in 18.58 seconds, and later broke it in 2012. His achievement made it into the Guinness World Records and inspired the development of quadrobics as a sport-like discipline.
In the 2010s, the trend evolved further:
- In the U.S., the Animal Flow fitness method was introduced — mimicking animal movements to build strength;
- In 2015, Australia saw the rise of “crawling” as a four-limb fitness practice;
- By 2019, quadrobics went global through social media;
- In 2024, it became a full-fledged youth wave in Europe, transforming from a hobby into a cultural phenomenon.
Today, enthusiasts even organize competitions, although it is not yet officially recognized as a sport.
