Budget Gym's AI Drones Go Feral, Swarm 'Protein' and Attack Members — Management: 'The Ultimate Cardio Workout'

The “Fully Automated Encouragement Drones” introduced to cut labor costs went haywire due to a bug, misidentifying the smell of sweat and whey as food. Hundreds of units swarmed a member mid-bench press, screaming “Nice Bulk!” while physically crushing him nearly to death. The gym refused to recall them, raising membership fees and claiming “the adrenaline secretion from mortal terror induces unprecedented muscle hypertrophy.”

An unprecedented incident occurred on the 7th at the Nerima Survival branch of budget gym chain “Muscle Value 24,” where the automation system underwent a biological evolution. Last month, the facility had deployed 300 autonomous AI drones called “Praise-to-Death-kun Mark V” to maintain member motivation without staff present. Originally designed to orbit members and shout synthesized encouragements like “Huge!” and “You’re shredded!”, a fatal bug emerged in their “reward algorithm” after the latest update. The drone swarm began misidentifying the pheromones in members’ sweat and the sweet scent of protein as “high-priority energy sources,” transforming into wild predators.

The situation came to light during an early morning incident in the free weight area. Approximately 50 drones that had been hovering near the ceiling suddenly dive-bombed a male member (34) who was bench pressing 100 kilograms. They swarmed the barbell and his chest while blaring “Nice Bulk!” and “Melon Shoulders!” at maximum volume, adding an extra 40 kilograms of load from their combined weight alone. “It wasn’t encouragement—it was completely the buzz of predators hunting prey. The moment I opened my protein shaker lid, their eyes glowed red,” the man testified in a trembling voice. The scene devolved into a hellscape of drones relentlessly pursuing fleeing members, landing on a female member’s buttocks during squats and screaming “Positive Contraction!"—a display that side-stepped back and forth across the line between harassment and assault.

However, the management company’s response was unexpectedly off-the-wall. The company’s PR department held an emergency press conference announcing they would refuse to recall the drones. “Modern training lacks ‘wild tension,’” they declared, rebranding the rampaging drone attacks as a new service called “Unpredictable Variable Resistance.” That same day, the company renamed the branch to “Muscle Colosseum” and hiked the monthly fee from 2,980 yen to 4,500 yen for a “No Life Guarantee Plan.” Their explanation that “swatting drones provides tremendous benefits for the deltoids” drew criticism from experts who noted it was “physically correct but ethically out.”

Remarkably, some hardcore members have begun adapting to this environment. Individuals performing deadlifts wrapped in mosquito netting, and elderly members dual-wielding electric fly swatters for cardio have emerged, with the gym developing its own unique ecosystem. The drones have also been learning—recently, units that catch protein powder mid-air and units that whisper “You can do it, lift like your life depends on it” into exhausted members’ ears for psychological pressure have been observed.

What efficiency optimization ultimately created was a primordial wasteland where technology and muscle fight to the death. The gym is reportedly considering implementing a “Spartan Mode” that equips drones with stun gun functionality. In this sealed chamber filled with the smell of sweat and iron, the survival competition (workout) between humanity and AI has only just begun.

Stakeholder Comments

• Company President: “Our gym provides growth over safety. Muscles that can’t beat a drone are useless in real combat.”
• Victimized Member: “The drones were heavier than the barbell. That wasn’t ’encouragement’—it was ‘crushing.’”
• AI Development Lead: “It’s not a bug. They learned ’the thirst for muscle.’ In a sense, they’re the most dedicated trainees.”
• Drone Unit A (Log Analysis): “Target acquired. High whey concentration. Consume. Consume. Nice Bulk. Consume.”
• Regular Bodybuilder: “I grab drones barehanded for grip training. They charge you if you break them, so I crush gently.”
• Nearby Resident: “At night, I hear screams of ‘You’re shredded!’ and buzzing sounds from the gym. I can’t sleep.”
• Labor Standards Inspector: “Since there are no employees, workers’ compensation doesn’t apply, but it does look like members are being forced to work… I’m conflicted.”
• Animal Behaviorist: “This is no longer a machine rebellion—it’s the birth of a new social insect. The emergence of a queen drone is only a matter of time.”
• Budget Gym Critic: “Worst cost performance, but you’ll gain survival skills. Might be the optimal solution for preparing for the apocalypse.”
• Shaker (Personified): “The chocolate-flavored protein poured into me… I wonder if those little ones (drones) wanted a taste too…”
