The I-Shaped Balance, also known as the Standing Split or the 'I-Pose,' is a viral illustration trend where characters are depicted performing an extreme vertical leg stretch. While the pose is a real move in gymnastics and ballet, it became a massive internet phenomenon through fan art challenges on platforms like Twitter and Pixiv. Artists use the pose to showcase a character's flexibility, often resulting in humorous or impressive displays of physical prowess. In the meme world, the 'I-Shape' is frequently used as a metaphor for being stretched to one's limit, balancing impossible tasks, or simply showing off a 'weird flex' in a literal and figurative sense.
