Miley Cyrus and Hailey Bieber Love These Black Bike Shorts for Their Workouts

It seems undeniable—the 90s bike short trend is here to stay. The form-fitting bottoms that your mom donned for aerobics class (which might have had you cringing back in the day) have now been spotted on this year's runways and on the likes of the most fashion-forward celebrities—from Kourtney Kardashian to Bella Hadid to Emily Ratajkowski.

So, it shouldn't be all too surprising that more A-listers are taking note and incorporating the stylish athleisure piece into their rotations. In September, self-proclaimed yoga lover Miley Cyrus chose a pair of Nike Women's Pro Bash Short (Buy It, from $28, amazon.com) for an at-home workout.

"Sometimes I'll improv and just do what my body tells me! Today it's a mix of Pilates and Ashtanga Yoga," the singer captioned her Instagram story. Cyrus followed up with additional photos, allowing fans a glimpse into her yoga practice and core work, in which she uses resistance bands to further push her body. (

The star's post-workout selfie revealed how the shorts' waistband laid perfectly smooth against her waist and paired seamlessly with a Calvin Klein Women's Modern Cotton Lightly Lined Bralette (Buy It, $44, amazon.com). The compression shorts are ideal for yoga practice (and really everything from running to circuit training), where you really want to see how your body is moving, adjusting for proper form and alignment along the way.

Cyrus isn't the only celeb who prefers Nike bike shorts for her sweat session. Recently, Hailey Bieber took a pair of Nike Leg-A-See Bike Shorts (But It, $40, zappos.com) for a round in the boxing ring at Dogpound. The shorts hugged her body as she sparred with her instructor, always staying in place (i.e. zero slippage) as she moved swiftly around the ring, and didn't cause any distraction from her jabs and crosses, thanks to the high waist, longer length, and compressive fabric. She paired them with the Koral Activewear Sweeper Versatility Bra (Buy It, $65, amazon.com), a super sleek black cropped sports bra that's no only luxuriously soft but also has an edgy sheen to it.

While bike shorts have seemingly taken over the fashion scene, don't forget that they were actually designed by athletic brands to be worn in the gym—and for good reason. Most are made of sweat-wicking fabrics that pull moisture away from your body to keep you cool and dry throughout your workout. Plus, bike shorts combine comfort and style, making them simple to slip on whether you're pairing them with a cropped tank for your HIIT class or an oversized sweatshirt post-gym. And they come in a wide range of versatile rises and lengths, so you can choose a pair based on what makes you feel most comfortable.
