Forget 25 Days of Christmas — we're heading straight into 7 Days of Dancer Arms: Holiday Edition.

Want to feel stronger (and way more festive) in 7 days?

• Give your arms a sexy sculpt

• Strengthen your shoulders, back, and triceps

• Create definition in your arms

• Listen to some classic holiday music

Only 4 minutes per day for 7 days. Grab your dancer arms weights (3lb/ 2lb/ 1lb/ Balas/ bodyweight) and get ready to rock out to your favorite holiday songs. If you can watch holiday movies for 25 days in a row, your goal of staying consistent for 7 days of dancer arms will be a breeze.
