My routine has been going better than ever, but yesterday I think hurt my back somehow at work. I work in retail, I used one hand to slide a large amount of clothing down a bar by pushing it with my hand and twisting my back. Felt find then, but later at a bar, when I went to sit down on a stool, it just hit me. Pain on the left side of my spine, right between my upper and middle back. WOke up today and still feel that pain. Not sure if it was from what I did at work, that's the only thing I can think of. I worked my legs thursday. Today was suppose to be my back workout, my question is, should I do it anyways? even though my back doesn't feel 100% ? or leave it to next week? just take out dealifts? what do you guys think?
