I've got 2 questions about working the chest:
1. Whenever I work the chest I "feel" it around my armpit area. Is this normal or should I feel it all throughout my chest?
2. I started using DB's recently because one side of my chest was starting to lag a bit. When I use them though, should I rotate the wrist on the way up (meaning when they are down I'm using a hammer grip-- palms facing each other, and then when they are up the thumbs are facing each other)? I read that this allows a better stretch to be used at the bottom of the movement, but I don't think I've ever seen anyone besides myself actually do this; it doesn't take any of the emphasis off of the chest or do anything else counter-productive does it?
