Understanding Neutral Pelvis
To grasp what constitutes a correct pelvic position, it's essential to understand the concept of a "neutral pelvis." A neutral pelvis is the optimal alignment where the pelvis is level and balanced. In this position, the bony landmarks at the front of your hips (anterior superior iliac spines, or ASIS) and your pubic bone form a vertical plane when standing. When lying on your back, this plane should be parallel to the floor, like a bowl of water that is level and not spilling. This slight forward tilt is natural and helps support the normal S-shaped curve of your spine.
How to Check Your Pelvic Position
One simple way to check your alignment is the "Palms on Pelvis Technique".
- For standing: Place the heels of your hands on the bony protuberances at the front of your hips. Angle your fingers down and in so they form a vertical line with your thumbs. In a neutral position, your hands will be relatively vertical. If your fingers point forward, you may have an anterior tilt. If they point backward, it's a posterior tilt.
- For lying down: Lie on your back with knees bent and feet flat on the floor. Place your fingertips on your hip bones and your palms over your pubic bone. If your pelvis is neutral, your fingertips and palms should be level. If your hips are higher, it's an anterior tilt, and if your pubic bone is higher, it's a posterior tilt.
The Types of Pelvic Tilt and Their Effects
When the pelvis is not in a neutral position, it typically tilts in one of two main ways, which can have cascading effects on your body.
Anterior Pelvic Tilt
This is a forward rotation of the pelvis, causing the lower back to arch excessively. It is often caused by tight hip flexors and weak core muscles and glutes, which can be exacerbated by prolonged sitting.
- Symptoms: Lower back pain, tight hamstrings, and a protruding stomach.
- Associated problems: Can lead to poor posture throughout the body, including a rounded upper back and neck pain.
Posterior Pelvic Tilt
This is a backward rotation of the pelvis, causing the lower back to flatten. It is commonly associated with tight hamstrings and weak lower back muscles.
- Symptoms: Lower back pain, a flat-back posture, and tightness in the hamstrings and glutes.
- Associated problems: Can place stress on the intervertebral discs and contribute to pain.
Pelvic Obliquity
Less common but also significant, this occurs when one side of the pelvis is higher than the other. It can be caused by leg length discrepancies or conditions like scoliosis, and it can affect the knees, hips, and lower back.
Correcting Pelvic Misalignment
Fortunately, pelvic misalignment can often be addressed with targeted exercises and lifestyle changes. The goal is to correct muscle imbalances by stretching tight muscles and strengthening weak ones.
Exercises to Improve Alignment
- Pelvic Tilts: An excellent exercise for improving pelvic awareness and control. Lie on your back with bent knees and feet flat. Gently rock your pelvis forward and backward, feeling the movement in your lower back. This helps mobilize the lumbar-pelvic region.
- Glute Bridges: Strengthens the glutes and hamstrings, which are often weak with an anterior pelvic tilt. Lie on your back with knees bent and feet hip-width apart. Push through your heels to lift your hips until your body forms a straight line from shoulders to knees.
- Kneeling Hip Flexor Stretch: Targets tight hip flexors. Kneel on one knee with the other foot forward, in a lunge position. Engage your core and glutes as you gently push your hips forward to feel a stretch in the front of the hip.
- Plank: A full-body exercise that strengthens the core, including the abdominal and back muscles, supporting overall pelvic stability.
Lifestyle Adjustments for Better Posture
- Sit Smarter: Avoid prolonged sitting, and if you must, use a chair with good lumbar support. Keep your knees below your hips and your feet flat on the floor. Get up and move every hour.
- Stand Strong: Stand with your weight evenly distributed, shoulders relaxed, and a slight curve in your lower back.
- Sleep Soundly: If you're a side sleeper, place a pillow between your knees to keep your pelvis level. Back sleepers can place a small pillow under their knees.
Comparison of Pelvic Tilt Causes and Solutions
| Feature | Anterior Pelvic Tilt | Posterior Pelvic Tilt |
|---|---|---|
| Appearance | Excessive inward curve (arched back) | Flattened lower back (slouched) |
| Primary Cause | Tight hip flexors, weak glutes/abdominals | Tight hamstrings/glutes, weak core |
| Common Lifestyle | Prolonged sitting, pregnancy, high heels | Over-tucking tailbone, sedentary habits |
| Key Exercises | Hip flexor stretches, bridges, planks | Hamstring stretches, cobra stretch |
| Posture Goal | Engage core to pull pelvis back | Engage core to prevent tucking |
Conclusion
Knowing what is the correct position of the pelvis and working to achieve it is a powerful step toward improving overall health. The neutral pelvis provides the stable foundation your spine needs to minimize stress and prevent pain. By incorporating simple exercises and being mindful of your posture during daily activities, you can correct muscle imbalances and maintain proper alignment. This proactive approach supports a healthier spine and body, leading to less pain and greater mobility.

Taking control of your pelvic health is a journey, but the benefits—from reduced back pain to improved posture—are significant.
