Getting so friggin frustrated. I watch videos on how to do this exercise then I watch myself doing it in the mirror but I just can't seem to get it right. My back always looks as round as a basketball. I would like to actually be able to do this exercise with some weight on the bar but I know I shouldn't until I get the form right. Has anyone gone through difficulties with getting this form right and/or do you have any suggestions on how I can get it down? Thanks.
