about 3 days ago, I hurt my back while I was doing the pHS PE1>iM training...
It’s getting pretty better at it but I still have pain in my back that’s why I haven’t been doing exercise for a while...
I’m so worried about having a long period of rest and I’m afraid my flexibility is getting worse.
Why have I gotten injured my back? overtraining? if not, just my mistake the other day?
I felt a knot in my beck for a while Is that the reason why I got injured?
