^You said in your first post, what you ate. Do you take supplements such as creatine or whey protein to help bulk up? ...Hopefully not steroids.
Well done. I realize that you are working a slightly different muscle when you do incline and decline, but have you thought of other exercises to target those muscles? Just wondering your reasoning.
Another question for any gym rats, my trainer told me to do four sets, but I have always done three sets of 10-13 reps for general toning.
