This Trainer-Approved HIIT Workout Gear Can Stand Up to Serious Sweat

Alo Yoga 3" High-Waist Airlift Short ($64)

These best-selling shorts from Alo are made with the brand's Airlift fabric, a high-compression material designed to not slide down during high-intensity workouts. Pair them with a sweatshirt, and you've got a comfy ensemble to lounge or run errands in. If these look too short for you, don't worry: the brand offers the same shorts in a five-inch length.
