Improve Hip Mobility to Relieve Lower Back Pain: Key Exercises for Hip Rotation

Hip mobility plays a crucial role in maintaining a strong, pain-free lower back. Limited movement in your hips, especially in external and internal rotation, can force your lower back to compensate, leading to strain and discomfort over time. In this guide, we’ll explore why hip mobility is essential, provide a simple test to assess your hip rotation, and share effective exercises to improve your hip flexibility and stability.

Why Hip Mobility Matters for Lower Back Health

Your hips are fundamental to most of your movements, from walking and running to everyday activities. Proper hip rotation allows your pelvis to shift naturally and supports efficient movement without placing extra strain on your lower back. Without adequate hip mobility, your lower back may compensate to support your movements, often resulting in pain and stiffness.

For example, during walking, in the third phase of your gait cycle, your hips need to rotate externally to shift your pelvis and provide stability for a smooth push-off. Limited hip rotation can force the lower back to “crank” and overcompensate, which can lead to long-term back discomfort or even injury. Enhancing hip mobility can reduce the strain on your lower back, helping you move more freely and comfortably.

Testing Your Hip External Rotation

Before diving into exercises, let’s test your hip external rotation to see if you may be lacking mobility:

The Hip Rotation Test

Setup: Grab a broomstick, dowel, or similar stick. Stand with the stick beside you, placing it directly in line with your toes and holding it with your arm at a 90° angle.
Lift and Rotate: Lift the opposite leg to a 90° angle at the knee and hip. Keeping your knee aligned with your hip, rotate your knee outward to see if you can touch your heel to the stick.
Assess: If you can’t reach the stick without shifting your body or need to “cheat” by leaning, it indicates limited external rotation in your hip. Test both sides to identify any differences in mobility.

If one side struggles more than the other, focus on improving external rotation on that side with the exercises below.

Exercises to Improve Hip External Rotation

Now that you know where you stand with hip rotation, here are exercises to increase your hip flexibility and reduce the need for lower back compensation:

1. Hip 90-90 Stretch with Forward Lean

This stretch focuses on increasing external rotation and targeting your hip and thigh muscles.

Position: Sit on a mat with your front leg in a 90° angle in front of you and your back leg also bent to a 90° angle beside you.
Set Up: Place a stick next to your front foot to ensure alignment. Rotate your torso forward to face your front leg.
Movement: Slowly lean forward, “scooping” your torso toward your front leg. Keep your knee aligned with your little toe and avoid letting it cave inward.
Reps: Lean forward as far as you can without lifting your heel off the ground. Return to the start and repeat for 10-12 repetitions. Perform 2-3 sets per leg.

This stretch helps activate your inner thigh and outer hip, promoting flexibility and strength in your hip muscles.

2. Side-Lying Hip Rotation

This exercise builds external rotation strength by isolating your hip while maintaining core stability.

Position: Lie on your side with your lower leg bent at a 90° angle in front of you and your upper leg extended straight.
Setup: Place your elbow on the floor to support your upper body, keeping your upper hand on the floor for extra stability.
Movement: Lift your upper leg while rotating your torso outward and upward, aiming to keep your pelvis steady. Avoid arching your lower back, focusing on rotating from the hip.
Reps: Rotate up and down for 10-12 repetitions, completing 2-3 sets on each side.

This exercise stretches your upper inner thigh while improving rotation strength in the lower leg, reducing the need for lower back compensation.

3. Bridge with Posterior Pelvic Tilt

The bridge exercise reinforces proper hip alignment and posterior pelvic tilt, counteracting an overly forward-tipped pelvis.

Position: Lie on your back with knees bent and feet flat on the floor, arms by your sides.
Setup: Focus on tilting your pelvis back to flatten your lower back into the floor.
Movement: Lift your pelvis slowly off the ground, moving vertebra by vertebra. Stop just before your back starts to arch, maintaining a slight posterior tilt in your pelvis.
Hold: Push your heels and the balls of your feet firmly into the ground, holding the position for 20-30 seconds. If you want more of a challenge, lift one leg while keeping your pelvis stable.
Reps: Perform 10-12 lifts or holds for at least 30 seconds, and repeat for 2-3 sets.

This exercise encourages the glutes to activate, improving pelvic stability and hip control, which reduces strain on the lower back.

Putting It All Together: Improving Your Gait and Lower Back Health

These exercises collectively improve your hip’s external rotation, preventing your lower back from overcompensating during everyday movements. With regular practice, you should notice greater ease in walking, reduced lower back strain, and overall improved movement quality.

By prioritizing hip mobility, you’re not only supporting a healthier lower back but also enhancing your body’s natural movement patterns, allowing for better performance and less discomfort in daily activities. These simple yet powerful exercises can be done at home, making it easier to integrate them into your routine.
