The Strange Anatomy of AI-Generated Fitness Images
This image shows a grid of illustrated workout exercises. Several poses defy basic anatomy and physics. Limbs bend in impossible ways; weights float unsupported; joints appear disconnected or misaligned; and some exercises require a dysmorphic clone of oneself. These oddities are typical of AI models as they are trained on vast image datasets, attempt to replicate relevant forms, but do not truly understand biomechanics. Anatomical hallucinations of this kind are a recurring example of so-called AI fails. Whatever they tell us about the limitations of generative AI, don't try these exercises yourself!
