People love this workout, so get super-excited for today. It's a fun one.

This Shoulders/Arms – Circuit has 13 lifting moves, 2 of which are for your core. Even though these moves are familiar, they are going to feel very different in this sequence. Your shoulders will be used to stabilize the biceps and triceps moves, and the biceps and triceps are used to push and pull every shoulder move. Think of it as extra muscle and calorie burn. I can’t wait to see if I can lift my arms tomorrow. I might not be able to wash my hair?!??!
