Kourtney and Khloe Kardashian Try Aerial Workouts — and Can’t Stop Laughing! (PHOTOS)

Step aside, spin class. The Hollywood exercise world is quite literally reaching new heights with an aerial acrobatic workout craze.

Not only did Pink show off her impressive aerial skills during her "Just Give Me a Reason" performance at the 2014 Grammys (girl's got moves!), but now Kourtney and Khloe Kardashian are giving the workout a whirl.

The Keeping Up With the Kardashians stars went to The Aerial Classroom studio in North Hills, California on January 30 to try out the aerial and ring workouts. Throughout the session, the reality TV gals posted photos of themselves balancing on a purple aerial silk and giggling while sitting in the rings.

Khloe wrote, "For some reason this ring workout made me hysterically laugh!!!"

Kourtney also joked, "I believe I can fly...this is really just to show @thescottycunha my amazing ponytail. #aerialacrobat."

So maybe Kourtney and Khloe aren't joining the circus so fast, but hey, the class should make for an entertaining scene on their show!
