Kim Kardashian learned to "tap it back" when she hit up SoulCycle in Beverly Hills Monday—but it's likely the Keeping Up With the Kardashians star already knew a thing or two about popping that booty!
The 33-year-old reality star rocked a tight black top and matching pants for the indoor spin class, which helps riders burn between 500-700 calories in a 45-minute workout. It was a family affair, as Kim's sisters Khloé Kardashian and Kendall Jenner, plus mom Kris Jenner, also showed up to sweat it out.
They aren't the only famous SoulCycle fans: Oprah Winfrey celebrated her 60th birthday at the West Hollywood outpost in January (and has signed up for more classes since then), and Sean Avery, Lo Bosworth, Jake Gyllenhaal, Katie Holmes, Vanessa Hudgens and Kelly Ripa are regular riders.
Khloé later posted a Vine video of Kendall and Kim spinning away, captioned, "Fast mo and slow mo."
Kim has been trying a variety of workouts since giving birth to daughter North West in June 2013. Last week, she was spotted filming Keeping Up With the Kardashians with Blac Chyna at Barry's Bootcamp. In October 2013, Kim's fiancé Kanye West even joined her for a 6:30 a.m. session in Sherman Oaks, Calif.
Kim's hard work has clearly paid off—and we have no doubt she'll look amazing in her wedding dress!
