HIIT workouts are hard, and this one is no exception. The difference from your typical Tabata workout: this one features hip-hop moves. Lead by dancer, choreographer, and trainer Keaira La Shea [1], you get to dance while you burn up the calories and work your legs with some sassy squat variations. You can purchase Keaira's workout DVDS here [2]. Tuck jumps have never been so fun.
