In "Starting Strength", Mark Rippetoe wrote that there are people who simply cannot rack the bar as required for a Power Clean due to an "abysmal anatomy". I am indeed having a hard time racking the bar, for when my humeri are parallel to the floor, my hands are somewhere behind my neck.
If I use a wider grip (actually the widest grip, my bar allows), it's slightly better, but the bar does not really sit on the delts, but rather on my collarbone, unless I push the shoulders to the front really violently, which is quite uncomfortable.
My bar is something around 1,70 m I think and I have no access to longer bars, let alone Olympic bars (for the scope of this question, assume that I have no possibility of getting one in the future).
Is there any chance for me of racking the bar as required for the Power Clean? Is this really an issue of too long forearms, or is this a mobility issue? (FWIW I have not tried to progress on the Power Clean any further, for I'd like to fix the racking first [as suggested by Mark Rippetoe])
