I just completed this superset workout: https://www.fitnessblender.com/videos/kellis-upper-body-workout-for-arms-shoulders-and-upper-back-upper-body-superset-workout

This workout is definitely my favorite upper body workout. I know that I will be sore tomorrow! My arms are still shaky as I am typing. If you haven't tried this workout yet, I highly recommend it if you really want those arms to burn!
