Don’t hog the leg press while prompting Claude.<\/p>\n
A screen with the logo of Fitness SF, a Bay Area chain of gyms, went viral among techies on X and Instagram on Monday. The image instructed gym-goers to refrain from writing code or prompting AI<\/a> during their workouts. “Be present. Lift harder. Ship later,” the image reads.<\/p>\n Troy Macfarland, Fitness SF’s director of marketing, said, however, that the image was an “AI-generated fake.” The gym does have etiquette signs that mention phone usage and being courteous, he wrote, but none mention vibe coding.<\/p>\n “This person altered our actual images displayed on the screen,” Macfarland wrote. “I will give an ‘A’ for creativity to him.”<\/p>\n It’s not clear whether the image was generated with AI, Photoshop, or some other tool. Ian Brash, whose post with the image got almost 7,000 likes, did not respond to a request for comment.<\/p>\n In San Francisco’s AI mania, it’s no surprise a sign like that blew up on X. Techies weighed in, cracking their own jokes about how tied they were to their coding agents<\/a>.<\/p>\n One X user told Fitness SF to give their copywriter a raise. A Cognition engineer<\/a> said that vibe coding between sets was encouraged at his company’s gym.<\/p>\n “Vibe coding at the gym?” one X user wrote. “You’re worried about the wrong weights.”<\/p>\n One reaction image often appears in the comment sections of posts like this one. It shows a muscled man, holding a giant nuclear bomb in his hands, jumping into the city of San Francisco. One VC posted it with the message: “Even I have limits.”<\/p>\n Want more Business Insider in your news feed?<\/p>\n \n Add BI in Google so our reporting is easier to find when you\u2019re searching for what matters.\n <\/p>\n Claude Code and cardio<\/p>\n The sign tapped into two of the buzziest subcultures in tech.<\/p>\n First, there’s AI coding. Ever since the launch of Claude Code and OpenAI’s Codex, engineers have been tied to their phones (or walking around with half-open laptops<\/a>) to continue building. Some techies told Business Insider that their love of vibe coding<\/a> created distance between them and their girlfriends.<\/p>\n
