Pelvic tilts are safe for just about anyone, even if you’re pregnant. For your tilts to be as effective as possible, it’s helpful to understand which muscles they target, how those muscles may contribute to lumbar pain, and the finer points of performing them.

This article explains the muscles used in pelvic tilt exercises, and why it’s important to strengthen them. It gives step-by-step instructions on how to perform a basic pelvic tilt.

Targeting the Core

The core is made up of many different muscles of the front, back, and sides of the torso. When the core is strong, it provides support for the rest of the body, preventing postural imbalances and instability that can contribute to pain and even injury.

By contrast, when core muscles are weak, postural alignment is thrown off and the entire body lacks adequate support.

Pelvic tilt exercises are designed to strengthen some of these core muscles. Research has found that those engaged most are two specific abdominal muscles.One is the multifidus, which extends and rotates the spine.

The other muscle is the deepest of the abdominal muscles, the transverse abdominis, which wraps around the spine to provide stability.

Basic Supine Pelvic Tilt

Pelvic tilt exercises do have a few variants. The simplest, which is performed while supine (lying on your back), is safe for most people, including beginners and those experiencing back pain.

Advanced exercisers who want to really challenge their core muscles can do them while standing with their back against a wall. Women who are in the late stages of pregnancy should do pelvic tilts while on all fours.

To do a basic pelvic tilt:

Lie on the floor (or on a mat on the floor) with your knees bent and your feet flat on the floor. Extend your arms alongside your torso, palms facing down. The back of your head should be touching the mat and your neck should be aligned with your spine. Allow your back to maintain a natural curve, leaving space between your low back and the mat. You should be able to slide your hand into this space. Inhale. As you exhale, engage your abdominal muscles, allowing that action to tilt your tailbone upward and close the space between your low back and the mat or floor. You’ll feel a gentle stretch of your low back. Inhale, allowing your spine and pelvis to return to the original position. Do 5 to 10 reps.

A Word From Verywell

Although simple to do, when practiced regularly pelvic tilts can strengthen your abdominals, ease low back tension and pain (if this is an issue for you), and optimally position your pelvis. Be patient: While some people find quick relief for low back tension with this exercise, it usually takes time to build muscle and alleviate pain.
