Well, yesterday was my day off and I took it easy... However, when I woke up this morning the back of my right shoulder was hurting like hell! I don't know what happened? Maybe I slept on my neck wrong or something, but it hurts. I've been doing some light stretching on my shoulders to try and loosen it up, but it still is sore, but as of now not quite as sore. So, to my disappointment, I have to miss today's cardio! I was thinking that although it's still sore that I might try and get through it this afternoon, but then again, I remember that if something is that sore, or injured (which I don't think is the case) that you need to just lay off for a minute...so, this is my first missed workout...I feel guilty. Hopefully tomorrow I will wake up and it will be gone because I have no idea how it got so damn sore.
