I was doing stiff-leg deads a few days ago and I felt a twinge in my upper abdomen. It quickly went away but now a few days later it is really giving me some nasty chest pain. I am guessing it is costochondritis (cartilage sprain) but anyway...
Without seeing a video, are there any form issues that likely caused this or is this a common thing that is just going to happen? Maybe I had the bar too far forward when I started the pull? In the stiff leg the bar is out in front more so I guess the nature of the lift puts more stress on the abdomen but I don't know.

I kind of don't want to bother with these anymore as they are awkward anyway and RDLs are about just as good.
