4 butt-sculpting moves from Kim Kardashian’s personal trainer

While there’s no way to feed the junk in your trunk, you can put your “back” into some of the moves that make for a cover-worthy booty. We got the basics of KimKardashian’s#breaktheinternet routine from Joel Bouraima, her personal coach at L’Usine in Paris.

Get on your side, using your elbow for balance. Raise and lower your leg in a scissor movement, remembering to keep your foot turned toward the ground. Depending on the position of your leg, you work on the back of the bum (raised leg pushed a bit backward), the side (leg in line with the body) and the top of the thigh (leg pushed a bit forward).

Get on all fours. Extend one leg toward the ceiling, keeping your back straight. Hold for 30 seconds. As it gets easier, try to hold it for a minute on each leg. For better results, use an exercise rubber band or ankle weights. If you just push the leg without extending it, you will work on the back of your thighs, which helps create the curve between the leg and the butt.

The squat is a classic exercise, easy to do anywhere and works wonders. Make sure you’re not bending forward; always keep your back straight as you go up and down. Your butt goes backward and your knees should always be on the same vertical line as your feet. Repeat for 30 seconds, then try 1 minute. To really accentuate the effect and develop the posterior, use a workout bar and add some weight, but keep it under 15 squats.

By making your waist skinnier, you can give the impression that your butt is bigger — which Kardashian used to great effect on the Paper cover. To make your waist thinner, do a side plank and hold it for 30 seconds to 1 minute. You can add some weights to make it harder and more efficient. For an even tighter sculpt, sit on one side of your bum and try to touch your feet with your hands, while pushing your legs up.

Repeat until you feel the burn!
