Yikes! Back twinge

That is what I felt shortly after waking up, so new plan for the week. No lifting. I'm taking the week off leading up to squat camp because I'd rather be a little weak than injured. I suppose last month there was almost a week off when the gym had short holiday hours, and hope this doesn't drive me insane. Yoga and cardio will have to do, maybe I'll revisit some Spin classes or take some boot-camp stuff. That might make me want to lift real weights though. And do I want to be out of practice when I get there, or is it better to start kind of fresh? I'm completely confused.
