Looking to boost your booty in the New Year?

Certified fitness trainer and yoga instructor Dempsey Marks is breaking down the five moves that she says are the only ones you need to tone up your butt.

“I am a proponent of time-efficient, high-intensity workouts that don’t require you to spend hours training at the gym,” Marks, who created the PreGame Fit fitness and lifestyle program, tells PEOPLE. “I believe in training smarter, rather than harder to achieve results.”
