My standard advice is to avoid heavy direct arm work. Get your biceps and triceps stimulation primarily through your compound movements. If you must do direct work (and I don't deny that it can be profitable), don't do much of it and use higher reps. And do it on the same day so as to facilitate recovery. Also, avoid overlapping workouts such as an 'arm day' one day and deadlifts another day, etc.
I had a 40 year old trainee ask me if he should do barbell curls with a 1RM weight. I told him only if he wants a ruptured biceps tendon.
