This Jennifer Garner-Approved Brand Just Launched Leggings with a Built-In Booty Lift That'll Have You Ditching Squats

As a lifestyle writer — covering everything from beauty to fashion — I spend most of my time camera-ready for meetings throughout the day. However, when I don't have to be completely made up and office chic, I live in loungewear. Now that I've added barre instructor and mom to my resume, comfy pieces for teaching and running to school drop off are even more of a must.

Even though my drawers are stocked with some of the most popular athleisure styles and brands out there, once I slipped on my first pair of Spanx faux leather leggings, I just couldn't quit them. After wearing these tights for nearly two years, I'm finally reaching for another pair — and, unsurprisingly, it's from Spanx's newest launch. Enter: the Booty Boost Active 7/8 Leggings (Buy It, $98, spanx.com). (FWIW, I'm not the only Spanx fan — the brand counts Jennifer Garner and other Shape writers among its loyalists.)

What I love about the Booty Boost workout tights is that they are specifically made to accentuate your curves and give you the best butt ever, thanks to performance fabric and contoured waistband. The breathable, four-way stretch material allows you to move freely through your favorite workouts, while moisture-wicking and quick-drying technology keep you comfortable and cool. What's more, the ⅞ length hits between the calf and ankle (flattering on both petite and tall bodies) and is perfect for year round wear.

The Booty Boost Active 7/8 Leggings are available in four shades (black, dark brown, navy, and dark emerald — a greyish blue color), as well as in sizes XS to 3X to accommodate different body shapes. More great news? Shipping on these workout tights is free, but you'll want to hurry and add them to cart now, since the celeb-loved brand is known for selling out quickly.
