this is Rebecca
this is her 2nd pull of cleans during a Sunday clean session at CFC HQ
this can be fixed in many ways, the best for her stems from a longer upper body relative to torso and some previous mid line stability issues that we are working on...if you think its as easy as just telling her to straighten her arms you're mistaken...with Rebecca or someone who has longer arms relative to legs combined with or causing mid line weakness under higher loads (i.e. here in the clean)...the cue has to come from the set up and 2nd pull position to pull the shoulder blades down and back, and try to overemphasize the low back arch in order to fire the paraspinals especially through the thorasic area...this will help her have a "higher chest" when she gets that bar above her knees next time...this will make her brain believe that she is tall and can pull...in this pic, with the midline lost before the 2nd pull, her brain thinks it has to "find a way" to make it happen so her arms bend to move the weight
other cues for people can be unloaded locked arm shrugs from the hang repeated over and over pre clean efforts...this teaches them to lock those arms; checking the elbows as well in the set up and on video or pics for 2nd pull will allow them to get feedback on this
so...the Rx...when Rebecca does any pulling (rowing, dead liftting pertaining to improving clean, snatch DL, db cleans...) she must focus on overemphasizing keeping the mid back under tension in a pronounced low back arch position...with arms straight of course...and when she fails in this...she must lower weight until she gets it down path so as to not "get stronger" with poor movement...her clean and DL weight will drop for a while (the brain can only handle so much info) but will come back over time with higher progression...
