The good things to say about Billie Eilish and her music are endless. And, especially after her sweep at the Grammys, we really can’t get hits like “Bad Guy,” “You Should See Me in a Crown,” and “Bellyache” out of our heads. If you’re a fan of some Billie workout songs, you’ll really love these sweat sessions set to the 18-year-old’s replay-worthy tracks. Ahead, you’ll find full-body and dance cardio routines, along with one booty and one core workout, set to Billie’s unique sound and deep-reaching lyrics. Go ahead . . . duh!
