This one move will transform your arms and shoulders

Score a stronger, more toned upper body with this awesome new exercise.

Lea Michele hasn't been shy about her fitness journey. While filming Scream Queens in New Orleans, she's been sharing workout post after workout post on her Instagram account. And the benefits extend far beyond looking great: "Today @ErinRomney and I talked a lot during our session about the importance of exercise not just for your body but for your mind...and listening to your body for what you need that specific day," Lea wrote yesterday. "I'm so grateful to be feeling so strong both physically and mentally in my life right now."

The woman behind Lea's inspiring photos (and strong, toned physique) is Erin Romney, the founder of Romney, the New Orleans-based boutique studio that Lea has been frequenting. Oh, and @romneypilates' account is just as motivating—that's where we found this killer exercise, shown below.

The move works your arms, shoulders and core with a bonus lower body burner at the end. You need a set of light handweights, a BOSU ball and a pair of crazy-awesome sunglasses (kidding about that last one). If you're at home or just want to focus on your upper body, go ahead and ditch the BOSU. Ready to give it a try? Do 3-5 sets of 15 reps.
