Want a strong, toned, and functional core? Pilates is a great way to start. This low-impact workout combines flexibility, strength, and endurance in exercises that can be done either on a mat or using a reformer in class. No matter what kind of Pilates you're doing, core strength is the main focus; you'll flow in and out of poses with a yoga-like emphasis on breath. And since we're all about accessibility, we asked 10 Pilates instructors for their top ab moves you can do right at home, no equipment required other than a comfy place to lie down. Incorporate a few of these moves into your next core workout for a slow and steady burn that'll tone and strengthen your abs.
