not sure if WFS, but worth a read
7. The Elbows
One of the things that has been taking some thinking about is the position of the elbows. Ilya said to turn the elbows back in the overhead position. This is different than what I have been taught and have thought in the past. After it was brought up again, Zygmunt said that it isn’t so much about the direction, but more about everything being turned on. I must also note that they did not teach to reach up with the shoulders in the overhead position, but the shoulders were again, turned on, but in a more neutral position. While Ilya’s elbows are turned slightly back, his shoulders are not opened up in a way that we see when someone’s chest is falling forward. He still has a VERY upright posture. This posture was talked about and praised extensively and I believe plays a huge role in the ability to turn the elbows back in the catch. I still think you cannot turn them back if the chest is falling forward, but while an upright posture is maintained it shows to be effective.
8. The Wrists
This goes hand in hand with the elbow position above. They teach a straight wrist, and not an extended wrist while the bar is overhead. The reason being that it puts excessive pressure on the wrist and elbow. I originally taught a straight wrist as well, but over time I started being more relaxed on this position. Looking at the overall picture, I think the extended wrist allows the bar to sit back a little, but is something that can be better managed with a more upright posture. Pretty sure world records have been set either way though.
This is basicly the opposite as "crossfit" is teaching us with "show me your armpits", but that is oly lifting and this is crossfit.
