Taking to her Instagram stories, the 39-year-old said: “I got my sisters and my mom a Christmas present but I got myself one too. I’m working out right now and I’m gonna open this and show you guys what I got them. I hope my sisters and mom will like this!”
Kim also demonstrated by having her personal trainer Melissa Alcantra giving it a go.
She added: “Melissa’s testing it out. It’s the DB method and this is what I got my sisters, all my sisters and my mum, for one of their Christmas presents. God I feel it in my butt a lot. They’re getting them today.”
Momager Kris took to social media to share the fitness gift she received.
Sharing a video of the machine, which was wrapped in a huge red bow, she said: “Kim, what in the world is in this huge box you just sent me? This box is as big as I am. Oh my gosh. Whoa Kim, this is so incredibly crazy. Is this a booty machine?”
