I had my camera set in sport mode, and caught about 30 continuous shots of Stegen doing bar facing burpees near the end of the workout. In 30 shots (about three burpees), Stegen remained bent over the entire time!
I am not picking on Stegen (he got a big laugh about it afterward). Stegen does what many of us do when we reach that point of exhaustion. The mind overrides the body. In Stegen's case, mentally he felt it was easier to continue moving without standing up. In reality, he was bent over and compressing his lung cavity, thus, he was unable to take in full deep breaths. It felt easier, but in reality it was harder.
This is the beauty and the beast of of high intensity training. If you can maintain your brain and thus, maintain the integrity of your movement, the results are amazing. If you lose it, and let your mind run your body mechanics, you don't get the same results, and you risk the possibility of injury. Sometimes you have to slow down and get a grip in order to do better.
Just a little food for thought the next time a workout is getting the best of you.
