Identical twins Miriam and Michelle Carolus claim that their four-foot derrières are the result of intense exercise.

“We make sure we eat the same, exercise the same — everything the same,” Michelle tells Barcroft of their routine. “We try to do a couple of thousand squats a day to keep in shape. It won’t be all at the same time. It will usually be stretched over something like nine hours.”

The twins, who have almost 250,000 followers on Instagram, also revealed that they earned $30,000 after entering modeling industry as the “Double Dose Twins” two years ago.

The sisters are currently working for the same plastic surgeon and although they spent $5000 to perform a boob job, their best assets are natural.

“We would never consider surgery on our butts — our workout plan pretty much takes care of that,” Miriam says. “And when you do it naturally through hard work, it makes you feel a lot better about yourself.”

But, it is not easy to get that body, since hundreds of squats are required during their regular workout. The sisters squat up to 100 times each on a daily basis, working up to 2000 in total.

“We will work out the exact same and make sure that if one of us has done more, the other will have to catch up,” Miriam said.
