Hey C-vac........
Seem to hung up on the numbers......

Try going for feel and concentration......Work on your mind body....

Give your self a "rep-range" to work in instead of a number.
Meaning.....If you are doing a Flat Barbell Bench @ 210 third set, go for 7-11 reps... If you blast out 12 @ failure, then increase your weight slightly for the last set.....WRITE THAT DOWN!!

If you put one specific # in your mind, you tend to "mentally" tire out before you could physically.

As far as the Delt routine, hard to say caus I don't know what your delt's look like. Me personally, i could skip delt's every other week, b/c of response delt's have to training. Weird for a girl!!!!! But, you def. sound like you need some detail work in your routine....like lateral raises and rear delt flys. Front raises are more fun than upright rows to......
