The Fitness Marshall Goes K-Pop with BTS's Hit "DNA" and We Can't Even

We've danced with Caleb and crew to Latin beats, hip-hop hits, and Top 40 songs, but this is the very first time The Fitness Marshall is taking on K-pop — and we LOVE it.

The hit song has been huge in Korea; Caleb told us he thinks it's "Korea's Despacito." We feel that. We also feel that you won't be able to get through this insanely fun routine without getting a face cramp from smiling.
