Quadrobics: Why Kids Are "Going Wild" (7 Photos)
A unique subculture known as "quadrobics" has recently been taking off among teenagers. It involves dressing up as animals and mimicking their habits and movements. Quadrobics enthusiasts gather in groups, swap tips on crafting animal costumes, film videos, and generally have a blast. To outsiders, however, these gatherings of human-animals look bizarre, to say the least. So, what exactly is quadrobics, and why has it become so popular? 
The trend traces back to Kenichi Ito, an eccentric Japanese man who set a Guinness World Record in 2015 by running 100 meters on all fours in 15.71 seconds. It took Ito ten years of rigorous training to pull off the feat. He didn't just practice on track fields—he could often be seen sprinting on all fours through city parks. 
The quadrobics pioneer often complained about being misunderstood by society, even though Japan is usually quite forgiving of eccentric behavior. In one interview, he recalled:
"The police found my runs suspicious, and I ended up spending a couple of days in a holding cell for disorderly conduct. Once released, I headed to the mountains for a whole month to stay out of everyone’s way. But on my very first day there, a hunter mistook me for a wild animal and fired a shot. Luckily, he missed." 
Why Are People Acting Like Animals?
These days, seeing people in animal costumes roaming the streets barely raises an eyebrow in Japan. But quadrobics has expanded far beyond niche quirkiness and spread across the globe, primarily appealing to children and teens. Psychologists point out that young people are drawn to the sheer novelty of it—anything out of the ordinary feels exciting, engaging, and fun. 
On top of that, many kids today lack physical activity, spending most of their childhood glued to computers or smartphones. Traditional sports can feel demanding, boring, or simply too expensive for many families. A lack of attention from adults also plays a role; quadrobics offers a quick way to turn heads and get a reaction, even if it isn't always positive. 
Others are driven by a desire to feel agile, strong, fast, and connected with nature. Wearing animal masks, claws, ears, and tails, these teens don't just practice athletic moves—they sometimes approach passersby by scaring, teasing, or even scratching them. Unsurprisingly, not everyone is amused, leading to uncomfortable confrontations. 
Is Quadrobics Harmful?
Is quadrobics harmful to kids and teens? More likely than not. Setting aside the psychological and developmental aspects, "quadrobers" frequently suffer injuries, sometimes severe ones. The human body simply isn't built for quadrupedal movement. Moreover, hardcore practitioners go even further: they don't just mimic animal behavior, they actually eat pet food. 
It's no secret that pet food is formulated very differently from a human diet. Its ingredients are ill-suited for human consumption and can trigger digestive issues, vision problems, heart conditions, and immune system distress. Furthermore, even premium pet foods carry bacteria that are harmless to cats and dogs but can cause gastritis, pancreatitis, or even toxic shock syndrome in humans.
Quadrobics might still have a future, but perhaps strictly as an athletic discipline or niche sport—much like the recent rise of hobby horsing.
