I really want to get more lean and defined arms. I dont want to increase the size of my arms, just make them more cut . I want nice sexy muscular arms but not he-man arms. I like the size they are now but I need to be more cut. Its coming slowly, by bi's and tri's look nice but my delts are being stubborn. If I flex my arm to 90 degrees like holding a hammer then you can see that nice v shape on my arms but when I just let my arm hand straight down, you dont see anything from the shldrs. I have slow and heavy and pyramid upper body. If I recall when I did PUB I got good results but I havent done either of these two workouts in a long time because of time. I have been doing P90x shldrs and arms workout the past two weeks and feel it is a good workout, I lift as heavy as I can and am usually fatigued by the end of the workout. questions is will this workout give me the lean and cut look I am looking for or should I go back to PUB or SH? has anyone experimented with these?
