Cindy Crawford has been in the supermodel game for a few decades now. So it makes sense that over time, she’s come up with some ways to seamlessly fit exercise into her routine. Of course, taking care of her body is part of her job, which probably isn't the case for those of us sitting at a desk all day. Turns out, though, there’s nothing overly complicated or fancy about Crawford's workouts—which is probably why she’s been able to keep at them for so long.

In an interview with NY Mag's the Cut, the supermodel shared the workout routine she learned 30 years ago, which she's passed down to her daughter (also a model) Kaia Gerber. She explained that she does "20 minutes of cardio then weights." Her cardio—which she does at least three times a week—varies from trampolining, to running stairs, to hopping on the elliptical. Then, she spends about 30 minutes to an hour doing "old-school lunges, weights, squats, and bicep curls." She also adds: "Once a week, I try to go on a hike with a friend so I combine exercise and girlfriend time—it’s the best multitasking." Turns out, Crawford's doing a fair amount of multitasking in her fitness routine.

The best thing about Crawford’s routine is that she’s paying equal attention to both cardio and strength training.

It’s easy to focus too much on one component of fitness and neglect the others—let’s be honest, some of us just enjoy doing cardio more than lifting weights, or vice versa. What makes Crawford’s routine so effective, though, is that she does both. For a well-rounded routine, you should be working on all of the different components of fitness, not just one, trainer Holly Perkins, B.S., C.S.C.S., tells SELF. While we don’t have intel on whether or not Crawford’s spending time focusing on flexibility, it sounds like she’s working on both her cardiovascular fitness and muscular strength and endurance through her old-school strength-training moves. "You want to be improving all of those factors because that's going to mean improving your fitness all around,” Perkins says.

Crawford is also doing compound exercises, which makes any fitness routine more efficient.

"If she's doing walking lunges, bodyweight squats, push-ups, any kind of a compound complex movement, those movement patterns are so big and stimulating, relying on your biggest and most powerful muscles like glutes, hamstrings, and quadriceps," Perkins says. Doing compound exercises to work multiple large muscle groups at once lets you fit in more work in less time.

For example, when you’re doing a squat, you’re not just working your glutes (though they do take on the biggest workload). Your hamstrings, quads, and core all play a part in executing the movement, so you’re able to train all of them at once. Because more muscles are being used during these movements, your body has to work harder to both execute the moves and rebuild muscle mass after than it would with an exercise that isolates one group of muscles. That translates to both a greater calorie burn and bigger strength gains.

Trampolining, a favorite of fellow top model Gisele Bündchen, is also a great exercise to check off multiple fitness to-dos at once. According to Doug Sklar, a NSCA-certified personal trainer, trampolining works muscles in your legs, like your quadriceps, hamstrings, glutes, and calves, along with your lower back, on top of challenging your cardiovascular system. It’s a great way to work on both cardio and strength at once. “It's also very low-stress on the joints,” adds Perkins.

Plus, let's be honest: Trampolines are really fun. "There's something that just feels really good about it," Perkins says. "I don't know if it hails back to being a child, or what." Either way, finding a workout you love to do makes you way more likely to stick with it—so it’s definitely worth tapping into that nostalgia if it helps motivate you.

Last but definitely not least, this no-frills routine is really easy to do anywhere and with minimal (or no) equipment.

Perkins suggests that the reason Crawford has been following this routine for so long is because she can take is with her anywhere since there's no equipment required other than a pair of dumbbells. She could even do all of her go-to strength moves with just her body weight. "When it comes to fitness, it's really easy to find excuses not to do it, for all of us," Perkins explains. "If you can remove as many excuses and obstacles as possible, the more likely you are to set yourself up for success.” Not needing a gym or fancy equipment makes it easier to get it done wherever you are—which is equally important for a model who’s jet-setting to photo shoots as it is for those of us who are just trying to find pockets of time in our hectic schedules to fit in a workout.
