Cory Everson begins this workout with a short warm-up before getting started with shoulder exercises.  Section one begins with an overhead press using a barbell.  Cory actually does this behind her head, which could strain your neck as well as the rotator muscles of the shoulders, so I recommend doing this in front rather than in back.  She does 3 sets of 12 and then follows with a tri-set of lateral raises, bent over raises and front raises to target the deltoids (again, 3 sets of 12, use light weights!).  Section two is for the biceps and, again, you begin with a muscle building exercise (barbell bicep curls) for 3 sets of 12 reps.  She then follows with a tri-set of various dumbbells curls and finishes up with some interesting forearm work.  Section three is for the triceps and starts with a tricep press and follows with French presses, kickbacks and close-grip barbell presses.  All exercises are done in a 3x12 format, with almost no rest between sets.  You may want to pause your video for some extra recovery time!

Overall, this is a fast-paced workout that, incredibly, works every part of your arms and shoulders in only 23 minutes.  There's no unnecessary chit-chat, although Cory does flex her muscles quite a bit and makes corny comments about sensual shoulders and bulging biceps that will either annoy you or crack you up.  My only real complaint about this video (aside from the corny commentary) is that Cory speeds through the routine at a breakneck pace.  I barely have time to even pick up my weights, much less recover between sets.
