Genuinely surprised someone else on a non lifting forum knows the term "hitching". I appreciate the honesty and critique, really.
I disagree on hitching as a cause of injury though, the 315lbs is light enough that hip drive resulting in an injury is a negligible chance. And think about the bio mechanics of the lift, the danger comes from a lifters inability to bring the load past the knees. By the time I'm dragging it up my thighs the pressure is largely off my back.
Also, max effort deadlifts are rarely pretty no matter who you are. 315 is not my working weight as of yet, I just went for the best 5rm I could.
Also, You aware? You could just be some random who read some articles on the movement or you're actually a lifter, PM me brah.
*edit* Upon me just doing research based on very real concern about your above statement, Pha que2, from now on if I have to hike it up to lock out I'll just drop the weight. I found it really isn't dangerous as it is just bad lifting etiquette, many people frown upon it because you're sort of "cheating". Also means my back is not the weak point, it's my glutes/abductors. Will hit that glute/ham raise machine from now on. We all learn something new every day =D
