Remember a while ago when I wrote about doing the hundred push-ups program? And I said I'd be doing the same thing with slightly more advanced push-ups and also sit-ups? It turns out that was a bad idea.
I watched youtube videos about good form for sit-ups, and really didn't feel I was doing anything very strenuous. Yet, I have managed to injure myself. I sprained the ligament that goes down my spine on the right side (I had not realized this was possible), and now the right half of my upper body is in spasm. The left side doesn't feel so great either.
So now I am seeing a chiropractor three times a week until it stops hurting so much. He has given me stretches to do a couple times a day, and forbidden me to do any more push-ups or sit-ups until he says it is okay to start again. Alas.
