PHOTOS: Kim Kardashian loves see-through looks! Instagram Back in September, Khloe Instagrammed a picture of herself mid-squat at the gym. Her motivation? “Because no one ever wrote a song about a small ass,” she wrote, asking her trainer, “right @gunnarfitness???” He agreed, but he’s quick to point out that squats alone wouldn’t result in a body like that. “Khloe works so hard,” Gunnar told E! News earlier this year. “She’s killing it in the gym. There are no shortcuts.” She doesn’t just work on the bottom half of her bod, eitherpart of her routine, her trainer said, is doing plenty of plyometric pushups. “It’s like doing a jump with your hands,” Gunnar said.
