Yes, I'm sure some of you do them and have no issues. I decided to incorporate some pullovers into my once per week chest/back routine. I started out with some light weights on a triceps bar, bench in a semi inclined position. Went really easy, didn't go down behind the head. No problems. A few weeks later, I go a little heavier, and now i'm on a flat bench and going slightly behind my head. Big mistake. The next day, my right shoulder is killing me. The crazy thing is that I barely felt a twinge in my left side..only a tiny bit on my lat muscle. On my right side, I felt like EVERYTHING had been damaged..the shoulder, the lat, my trap. Everything hurts. WTF did I just do to myself, and did I screw up my serve forever? I actually played the next day in my league, and went easy on my serve. If I really started to hurt I was going to quit. However, I was able to go full out because the serve itself didn't cause any pain....what caused pain was putting my coat on, lifting things over my head, etc. 2 days after this stupidity and I'm still sore as hell. So, I got out the foam roller and worked the whole area over...seems like the real culprit was near my shoulder blade and lat..after rolling myself for a good while, I woke up the next day with almost no pain. 6 days later and I feel fine, but man, never again. What I think this exercise did was exposed any damage my shoulder already has from tennis, and exacerbated it. It was telling that my left side had almost zero pain. Any way, lesson learned.
