The controversy behind cross-fit training



A very nice article on the good and bad effects of cross-fit training by livestrong.com:

Cross-fit is intense, effective, and hugely popular. But is it also too dangerous?

Ryan Palmer had a tough week. On Monday, the 26-year-old job battled squat presses and ring dips. Tuesday, a clean and jerk set where he squeezed out 30 reps with 135 pounds. The following day, even though his muscles were still aching, he performed a total of 150 pull-ups and 150 burpees.

Palmer took a break from exercise on Thursday, but the next morning he went for a long bike ride. The following day his arms were uncharacteristically sore and swollen, his urine the color of black tea that had been seeping for hours. Instead of suiting up in workout gear on Sunday, he found himself in a hospital gown hooked up to an IV drip that flushed his kidneys with more than nine liters of saline. As his creatine kinase levels—the amount of muscle protein broken down poisoning his blood stream— declined at the pace of a snail, he pulled out his phone to send a tweet to his fellow athletes. With one flash of the camera, Palmer revealed the frightening results of a kidney test, and offered a simple caption: “Uncle Rhabdo, is that you?”
