Spring has officially sprung, and your wardrobe is shifting from sweaters to shirts. You know what that means? Time to kick-start your arm-toning routines. Julianne Hough is right there with you. The dancer just shared her two-step bicep routine [2] on Instagram, and we can't wait to try.

Her website has detailed instructions [3] for the exercise. It's pretty simple, though: grab your band, stand on it, and do 10 bicep curls on each arm. Voilà, Summer arms, here we come!
