Are your abs workouts all about the six-pack abs muscles (a.k.a. your rectus abdominis)? It's easy to neglect the others, but sculpting a strong core takes a literal 360-degree approach—and your obliques are an important part. These core muscles are essential to daily function—stabilizing your body, coordinating your breathing, and supporting your lower back.
You might think of obliques as your “side abs,” but all of your abdominal muscles are technically layered in the front, according to Kristie Larson, CPT. You have internal and external obliques that are responsible for rotating and flexing the trunk and working with the other abdominal muscles to create intraabdominal pressure (the sensation happening when you brace your core).
Meet the expert: Kristie Larson is a NASM-certified personal trainer at FitHouse and Rise by We in New York City.
There’s a common misconception that rotating will hurt your lower back, but “the ability to rotate and to manage rotation well is really fundamental to the way that we function,” Larson says. Rotating trains your body to handle heavy loads while avoiding pain or injuries, she adds. “Our trunk needs to be able to bend and fold and twist in order to execute everything that we do in daily life,” she says. (See, the obliques are clutch.)
Convinced to add an oblique workout to your routine? The oblique exercises below are the best in the game and perfect for all strength levels. Mix one or two moves into your core routine or full-body sessions, or string them together for a spicy sequence that'll set those side abs on fire. No matter what, focus on your form.
