J.Lo’s trainer spills the secret behind her strong core: a 4-part plank move

At this point, basically the entire world has come to an agreement that Jennifer Lopez’s body is nothing short of #goals—heck, even Victoria’s Secret models are striving for her booty. And she deserves all the praise: This lady works hard on her workout routine to stay strong and toned, sweating with her trainer on the regular to keep on building up her impressive physique—tough-as-nails abs workouts, included.

While J.Lo definitely has her go-to exercises—like Spider-Man push-ups for those impressive biceps and plenty of squats and lunges for her glutes—she’s all about planks for her core. Not just any planks, though: Her longtime trainer, David Kirsch, recently shared the core-busting routine he swears by with PopSugar. It involves not one but four moves in a series that’ll work your entire body. (Hey, being Jenny from the Block doesn’t come easy, people!) Between all the kickbacks and knee dives, this routine will have you feeling like a super-sore superstar in no time.
