Khloe Kardashian shared this pic of herself and Kendall Jenner inside trainer Gunnar Peterson's gym and - well, let's just say they have a strange way of resting in between sets. "I missed her so much and those abs were irresistible! #SisterSister," Khloe captioned the strange photo.
This isn't the first time a family member has invaded Kenny's space. Back in April, Kylie Jenner posted this Snapchat video of herself sticking her hand down Kendall's shorts.
Back to the gym stuff. The Kardashian/Jenner crew often makes their workouts a family affair, with Kendall frequently joining Khloe at Gunnar's gym when she's in town. After Kourtney Kardashian broke up with Scott Disick, Khloe and Kim joined Kourt for a little outdoor fitness sesh on her sport court.
Khloe recent workout partner, however, is the one making the most headlines as she just posted a pic of herself with rumored boyfriend James Harden after a spin class in Los Angeles. Wonder if she licked his abs, too?
