so I need some easy stretches. my back is so sore. I can barely move my whole body. I tried squatting and almost fell over. my bones are so stiff. I don't do a whole lot cuz I am always nursing her or folding clothes. I'm pretty much stationary. I try to stand most of the time but my body gets tired. help me please. I'm in dire need.
