Do you ever feel stiff in your lower back, or notice that it’s hard to move your lower back and pelvis when you try simple exercises?

You’re not alone.

Many people, especially women after 35, struggle with stiffness, reduced mobility, and a lack of awareness in their lower back.

This can quietly build up over time, leaving you with weak muscles, restricted movement, and a back that doesn’t feel as strong or supported as it should.

Why the lower back becomes stiff

When we sit, most of us naturally collapse in the lower back.

Our pelvis tilts backwards (a posterior tilt), our buttocks roll under us, and the lower back rounds. Gravity pulls us into that position day after day.

The problem?

If you then lie down on your back with bent knees and try to perform that same pelvic tilt voluntarily, it suddenly feels difficult or restricted. The muscles that should help you move there don’t always activate.

That’s because your body is relying on gravity to pull you into that rounded posture when you sit, but when you need your muscles to do the job, say, lifting something heavy, getting up from a chair, or bending forward, they’re not ready to support you.

The result is often strain, back pain, or that familiar feeling of your “back going.”

What we often miss in training

Most of us move our upper body through lots of ranges every day: bending forward, leaning back, rolling to the side in bed.

But the lower back?

It often stays locked, stiff, and undertrained.

Over time this stiffness leads to:

  • Less mobility
  • Weaker muscle contractions
  • Reduced awareness of movement in the area

It becomes harder to “find” your lower back muscles, pelvic floor, and deep core.

This lack of connection often shows up as recurring backaches, sudden twinges, or ongoing discomfort.

The hidden connection: core, pelvic floor, and back

Your lower back doesn’t work alone. It’s part of a system that includes your deep core and pelvic floor muscles. When these areas are stiff and undertrained, you lose the ability to control movement, generate strength through range, and keep your back safe during daily activities.

By training your lower back mobility, strengthening your core, and learning to activate your pelvic floor, you:

  • Protect your back from sudden strains
  • Improve posture and awareness
  • Build resilience for everyday activities
  • Reduce the risk of recurring back pain
  • Feel more connected to your abdominals and pelvic floor

How to start safely

The key is not just “holding your core tight” with a straight back, but learning to move through range and gradually adding strength. Here’s what to keep in mind:

  • Start small: Gentle mobility and core activation without load.
  • Build gradually: Add resistance and load step by step, especially if you’ve had back issues.
  • Seek guidance if needed: A physiotherapist can help you find the right movements and progressions.
  • Make it routine: Incorporate these exercises weekly to keep your back strong and mobile.

Final thoughts

Your back doesn’t have to feel stiff or unpredictable.

By reconnecting with your lower back, core, and pelvic floor, you gain not just strength but awareness and control.

This makes everyday tasks easier, reduces back pain, and gives you the confidence to move freely.

Strong through range = strong for life.
