Dance to Rich the Kid and Kendrick Lamar's New Song With The Fitness Marshall

"The more you hair flip, the warmer you get!" Caleb, Haley, and Bria of The Fitness Marshall got so into this fierce hip-hop dance, Caleb actually cracked his neck while hair flipping.

You too can get so into "New Freezer" by Rich the Kid and Kendrick Lamar, but please, go easy on your neck. Let's break a sweat, people!
