I noticed that my shoulders were having a bad day since waking up, but I tried to do what I could during sparring and black belt class. Once I got home I had to take ibuprofen though, which is something I don't really like to do. I did the requirements I could but my shoulders decided to not let me do as many negatives or even move my arms behind me or above my head for very long. Tomorrow, I will try to make up what I couldn't do today.
