Show 'em what you've got! Nearly a year after giving birth to daughter North West, Kim Kardashian is more confident than ever in her post-baby body. In fact, when Keeping Up With the Kardashians premieres its ninth season June 8, the new mom—who married Kanye West in May 2014—lets cameras tagalong as she and mom Kris Jenner take Sheila Kelley's S Factor pole dancing class.

"Drag your hands around your body," the instructor tells Jenner, 58, as she slinks around the pole with Kardashian, clad in a black tank top, shorts and fishnet tights, looking on.

As Kardashian, 33, explains in the preview clip, Jenner has been applauded by her daughter's friends for her uninhibited behavior. "My friends love it—they love to hang out with her, they love her energy, so I'm just going to go with it and try and have a good time," Kardashian says.

In addition to pole dancing, Kardashian has sculpted her figure since North's birth in June 2013 with cardio sessions, Pilates classes and the Atkins diet. "Kim feels confident again," a source close to Kardashian tells Us Weekly. "She worked really hard and is so motivated to stay fit."

Keeping Up With the Kardashians premieres Sunday, June 8 at 9 p.m. (EST) on E!
