Oh. and another comment about the IC..It seemed as if both Osten and Rupert's legs were the main weak points for them. Osten's knees were definitely shaking and Rupert was trying to re-distribute his weight when he was balancing the bar on his back. You'll notice that Savage kept his knees locked for the most part. Im sure it was incredibly painful but it kept his legs from shaking and giving out. Christa probably was able to last so long because of her legs. I dont think upper-body strength really played as large of a role as it might have seemed in this challenge. For the most part, the arms and chest weren't really being overly stressed since the weight was being lain across the shoulders.
