Ab Burner + Arm Burner Workout

Just wanted to pop in and post up the Arm Burner and Ab Burner workouts that I am f'in dreading made up to do after my run today.  I am planning to do the Ab routine through twice.  For the Arm Burner I am going to go with low weights and do each set of 20 twice with only a 30 second rest in between. This is because I want to sculpt my arms rather than beef up to hulk status.

If you tried it tell me what you thought and/or what you would change.
