The 'Fitness is My Passion' meme features a young boy in athletic gear, typically a headband and wristbands, posing as if he is a dedicated athlete while performing a low-effort or humorous activity. The image stems from a stock photo that gained viral traction on platforms like Tumblr and Pinterest around 2014, eventually becoming a staple of ironic internet humor. It is most commonly used to mock one's own lack of athleticism or to describe a situation where a person does something minor for their health—like choosing a Diet Coke with a large meal—and jokingly considers themselves a fitness guru. The phrase is frequently paired with unenthusiastic or contradictory actions to highlight the absurdity of the claim.
