First off sorry if this has been talked about, which I'm sure it has, but I don't have a sub so I can't search. When I DL i can keep my back arched and lower back straight until right about when my fingers reach the bar. When I grab the bar it seems like for the life of me I just CANNOT keep my back from getting rounded. I feel tightness in my groin area like my hips won't go any further and the only way to grab the bar is to round my back. Is this purely a flexibility issue or do I have week hips or something? This is seriously frustrating because I've been at this for almost a year and I just can't do it. I hate it.
