My upper body is growing quite nicely. The only problem I see is that my arms aren't growing like the rest of my body. I work out just as hard with my arms, maybe its just my mind. I dunno, my routine is 1 day chest, 2nd arms, 3rd back, 4th shoulders, 5th legs. My arm work out consists of ez-barcurl, skull crushers, rope-handle hammer curl, seated french press, one arm grip press down, and seated alternative dumbell curl. I do 5 sets at about 8 reps of each and increase weight as I go. Could it be the exercises? My mind? Do some body parts grow slower? Could it be that my arms don't agree with the exercises?? Any opinions oferred appreciated. Thanks
