I've been doing too much weight with horrible form. Used to do 225 on incline for 10 reps bad form. Started doing 145 and doing a negative for 6 seconds then going up in 4 seconds. My upper chest which I could never move is buringing like hell right now. A friend of mine does this on every set adn every body part and has grown like crazy and gotten very vascular. I found my new workout.
