Cindy Crawford Recreates Pepsi Ad Nearly 30 Years Later in Skintight White Top and Daisy Dukes

Cindy Crawford hasn't aged in almost 30 years! On Tuesday the 55-year-old supermodel recreated her iconic 1992 Pepsi ad, slipping into an identical pair of denim Daisy Duke style shorts and a tight white tank. "It's always a pleasure and a thrill to work with my friend @davidyarrow… and even more so when it's for a good cause. We returned back to the original Halfway House from  the famous @pepsi commercial I did in 1992 to recreate the moment (with a David Yarrow twist) in hopes of raising funds for the American Family Children's Hospital in Madison Wisconsin where my brother was treated for leukemia," she captioned an Instagram shot. "So far, with the help of David's gallery network across the globe supporting the art and its sales — we've already raised 1 million dollars for the cause. I also have to thank my dear friend, hairstylist @peter.savic who did the iconic hair for the original commercial… so i was thrilled he was able to be here for this version as well! Thanks also to @samvissermakeup for makeup and @allowitzstyles for styling. I think we nailed it! Such a fun day –– I can't wait to show you more. More on stories xo."

Cindy doesn't need a daily workout. "I work out with my trainer, Sarah Hagaman, three mornings a week. We do circuit training for the whole body using weights, some machines, and my own body weight with lunges and squats. We usually do about 10 minutes of weights and then a five-minute cardio segment. Right now we are into running stairs, but we switch it up. We repeat the 10-minute weight and five-minute cardio at least three times and then we finish up with abs and stretching," she told Shape. "If I can squeeze in a hike or bike ride with my husband or a girlfriend during the week, that's just a bonus!"

What is Cindy's key to passing cardio time? Entertainment. "I put on an audiobook or music while I run the stairs at my house for 20 minutes. I just finished the Amy Schumer one, which was fantastic," she told The Cut.

Cindy enjoys working out with others. One of her favorite classes is at the S Factor pole dancing studio in LA. "[It's] so much fun to do with a group of friends," she explained to InStyle. "They keep it really dark, so it's almost impossible to feel embarrassed." She also enjoys hiking with friends. "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," she added to The Cut.

Scheduling her workouts keeps Cindy accountable. "I think having a scheduled appointment works for me. That way, I don't really have to think about it," she told Shape. 

Cindy tries to eat a diet of whole foods with nothing processed. "Diet-wise, I don't eat crap, and I don't eat a lot of packaged foods," she told Into The Gloss. "On a typical weekday I usually have a protein shake for breakfast because it's fast—I need to get the kids out the door… For lunch I'll have salad, sometimes with chicken, sometimes without. For dinner we'll go for sushi, or if we eat at home I'll try to make a meal like turkey meatballs with pasta, a salad, and a vegetable."

Cindy makes sure to get enough H20. "I also drink three bottles of water during the day, except for when I'm on location, as the bathroom could be 10 minutes away," she told Harper's Bazaar. You will also find her sipping on green tea, green tea lattes, and a shake she conducts herself with cup of almond milk, a cup of spinach, a handful of fresh mint, two scoops of Billy Merritt's Infinity Greens, and protein powder.

Cindy keeps her abs strong with the help of an intense workout routine, which she recently shared on Instagram. It includes standing bicycle crunches, sumo squats, and planks.
