Amanda Cerny hospitalized after 75 Pilates reps

Amanda Cerny ended up in the hospital after pushing way too hard on a Pilates machine, and she's explaining the whole thing from her hospital bed. She did 75 reps targeting her adductors on a Friday, felt fine Saturday, then woke up Sunday with thighs literally twice their normal size and constant pain even at rest. She consulted ChatGPT first (which told her she was fine as long as her urine wasn't Coca-Cola colored), and then it was. She finally went to the doctor the next morning and was diagnosed with rhabdomyolysis, where shredded muscle protein overwhelms the kidneys. Now she's on an IV to dilute her blood and prevent kidney failure, speaking from the hospital in glasses and a patterned pajama set, hoping other people learn from her mistake before going that hard on a small muscle group.
