Push Ups - Day 4

First week completed, and now I’m up to 33 consecutive during the progress test yesterday morning. However when I woke up this morning I felt something terrible under my right shoulder blade.
So after I got up, I did some stretching and tried my first set. Four push ups into my back was killing me. I had my wife massage it out a little and tried, again. No luck. But I didn’t want to give up. So I tried on my knees, still too much pain. So I conceded to do some wall push ups, simply to stretch out a bit – I worked through the entire routine with mild pain. I’ll do some more stretching tonight and we’ll see how Wednesday goes.
