Why simulate a vertical sweat sesh on a stair climber–esque machine at the gym when you could instead channel your inner Rocky and run up and down a few flights IRL? It's one way Jennifer Lopez and her pro-athlete boyfriend Alex Rodriguez crush their fitness goals—and you can get quite the workout by following suit.

On his Instagram, Rodriguez's shared a video of the duo sweating it out at an outdoor track doing some burpees, planks, jump-roping, and even barbell squats. The stairs, though, might have been the hardest part of all: According to one exercise physiologist and trainer, it's easily one of the most-intense forms of cardio around.

"It feels like it's more work because it is more work," fitness expert Pete McCall told Self. "On the way up, you're doing a lot more hip flexion and extension—your hip is going through a much greater range of motion [than with walking or running], so you're getting more work out of your hip extensor muscles."

So how do you go about getting a J.Lo-worthy workout? Based on this workout from McCall, simple is best: Just sprint to the top of the stairs for 6 to 10 seconds, walk or jog back down for 30 seconds, and repeat five times. When you're finished, rest for a couple minutes and repeat the entire process for two or three rounds, depending on how you feel, he said.

Oh, and don't forget to grunt through the tough parts (it scientifically helps your workout!) and listen to "Eye of the Tiger" in your earbuds (you know, for an added thematic effect).
