But the core of their phenomenal bodies is credited to their insane workout regime.
Introducing the man behind showbiz’s most famous bodies – the Kardashian’s trainer Don aka Don-A-Matrix.
Khloe and Kourtney have been killing the fitness game, thanks to this machine of a trainer!
Check out some of the crazy workouts in the video player below. Post continues!
The personal trainer, who crafts circuit workouts that target the legs, butt, and arms, works with Hollywood’s fittest including Kanye West, Fergie, Josh Duhamel, Will.i.am and David Boreanaz.
The lifestyle coach not only has a science degree in Health, Physical Education and Recreation but also certificates in a range of workout regimes.
Don, who goes by DB, developed the Matrix Method combining his skills as a fitness educator and principles learned as a lifetime athlete and coach.
The LA based trainer’s clients love his “sports game” inspired method which features four quarters. Each quarter has 3 sets of two different exercises, combined with rest or relief periods after each quarter.
Don certainly knows how to make these ladies sweat…
But clearly they’re loving the results!
Anyone who watches the Kourt or Khloe’s Snapchat will know these ladies love working out with their machine of an expert… Even if it is SERIOUSLY intense!
The sisters train with the expert 3-5 times a week and workout for anything between 45 minutes to an hour.
Speaking to E!News Don revealed it was Kourt who first discovered him.
“I was on tour with the Black Eyed Peas and Kourtney attended a concert while in NYC, and she loved how I had Fergie’s body looking,” he said.

In fact it was her trainer that whipped her revenge body back in shape following the birth of her third child, Reign.
Understandably, the 37-year-old, who is in the best shape of her life, “swears by the program.”
“Along with weight loss, her body fat percentage and fat mass has decreased tremendously and lean muscle mass has increased. Most people think it’s just weight loss to achieve the desired physical goal, but toning while achieving weight loss will help you get to the physical goal faster,” Don explained of the changes in the hot mama’s body.
So what does the reality star love to do?
“The plank is a favorite, but we take it to another level opening and closing the legs like scissors while at the same time raising and dropping the hips! So not only are you strengthening the core but also timing the hips, thighs and waist.”
Continuing, “[We also do] the trunk twist along with a back row using the bands. The benefit of this exercise will give you flat abs and coke bottle obliques while removing those fat handles from the back and arms.”
We’re officially putting down the chocolate and heading to the gym. STAT.
Try keeping up with that bod!
