Why do you have to do shoulders first? Injury?
therefore I can never do a full upper body workoutanybody else have this issue?I don't know how people can do a FULL hard core upper body session...
You're not giving nearly enough info for me to understand just exactly what is you think is happening. Typically when I'm training a client on full body I use the Steve Jarrell method and go chest/back/shoulders/arms in that order. Describe the workout and the issue more clearly so I can put you on a program.
