The seated pelvic tilt, also called a seated pelvic rock, is a gentle mobility exercise done while sitting. It involves slowly rocking your pelvis forward and backward to move your lower spine.
This movement is often used by people who sit at a desk for long periods. It can be a simple way to bring some gentle motion to the lower back without leaving your chair.
What the seated pelvic tilt works
The seated pelvic tilt focuses on creating gentle movement in your lower back and pelvis. It also lightly engages your core abdominal muscles as you move between the two positions.
How to do it
Starting position: Sit upright in a chair with your feet flat on the floor and knees bent comfortably. Rest your hands on your thighs.
- Gently arch your lower back, tilting your pelvis forward so your tailbone points out behind you.
- Then, gently round your lower back, tucking your tailbone underneath you as if slumping.
- Move slowly and smoothly between these two positions, coordinating the movement with your breath.
What you should feel
You should feel a gentle rocking motion in your pelvis and lower back. You might also notice a light engagement of your abdominal muscles as you perform the movement. This exercise should not cause any sharp pain.
Common mistakes
- Moving the upper body and shoulders instead of isolating the pelvis.
- Holding your breath.
- Moving too quickly or forcing the movement into a painful range.
Make it easier or harder
- Easier: Reduce the range of motion.
- Easier: Place your hands on your hips to help guide the movement.
- Harder: Perform the movement while standing with knees slightly bent.
Fitting it into a desk day
This is a quiet and subtle exercise, making it easy to do right at your desk. Because it has low visibility, you can perform a set during a phone call, in a meeting, or between tasks to gently mobilize your back after sitting.
Quick questions
How many seated pelvic tilts should I do?
You can start with one set of five to ten repetitions. It is designed to be done a few times throughout the day.
What is a common mistake when doing a seated pelvic tilt?
A common mistake is moving the upper body and shoulders instead of isolating the movement in the pelvis and lower back. Also, be sure to breathe steadily and avoid moving too quickly.
When to see a doctor or physio
You should stop the exercise and consult a doctor or physical therapist if you experience certain symptoms. This is especially important if pain is sharp, shoots down your leg, or gets significantly worse with the movement.
- Sharp, shooting, or radiating pain into your buttocks or legs.
- Numbness or tingling.
- The movement significantly increases your back pain.
Skip it or ask first if:
- You have a recent back injury or have had recent surgery on your back or abdomen.
- You have an acute spinal condition, unless cleared by a healthcare provider.
