If you've suspected that your "side butt" is a separate (and v. important) entity of the gloriousness that is your booty, you are right! Allow fitness nerd and badass certified personal trainer, Breanna Cummings, Equinox Group Fitness Instructor on Variis, to explain.

"The side butt is actually called the gluteus medius," says Cummings. She says your glutes are made up of multiple muscles, and the glute medius is often the most underdeveloped one. Sad! "Because this muscle is so difficult to train, it often gets forgotten—but not in this workout."

The six moves below work together to target your lower body—especially that side butt. Feel free to perform each of the exercises without resistance. When they become too easy, place a mini resistance band right above your knees for more intensity. says Cummings.

The workout

Perform the moves below back to back for the time noted. After completing the circuit, rest for 30 to 45 seconds. Repeat the series of moves four times for a 30-minute sesh.
