“We’re back in the gym heavy!” wrote Kim Kardashian West alongside a picture of herself and her personal trainer Melissa Alcantara on Instagram today. Pausing their sweat session for a snap, the beauty mogul posted up against a piece of fitness equipment, leaning into a derriere-showcasing pose. The secret behind Kardashian West’s sculpted backside? That would be weight training, as evidenced by her protective wrist straps.
“I would say every 6 months I take two weeks off from lifting,” she continued in the caption. “Sometimes you just need a break to recharge and chill, but then I miss it so much and [it feels] so good to be back at it.” Since enlisting Alcantara’s help back in 2017, Kardashian West has been open about how incorporating weights has helped tone her muscles and define her famous frame. And while the Alcantara-curated routine is all-encompassing, including squats, deadlifts, and lunges, there’s one weight-assisted move that stands above the rest for those who want to whip their booty into shape. “For anyone looking to get a serious butt workout in, it takes more than just one move,” says Alcantara. “But if I had to choose, it would be weighted hip thrusts, which seriously work glutes and hamstring muscles.”
And don’t be fooled by how pristine Kardashian West’s hair looks—her new sleek chopstyled with a clean center and swooping ends—the posterior chain-targeting move is not for the faint of heart. But her curvaceous physique is proof enough: picking up the weights is well worth the burn.
