Core Exercises for Lower Back Pain

John Miller Physiotherapist Erin Runge Physiotherapist
Article by John Miller & Erin Runge

Core exercises for lower back pain are commonly recommended by physiotherapists because the deep abdominal and spinal muscles help stabilise the spine. When these muscles work effectively, they support the lumbar vertebrae, control movement, and reduce stress on spinal structures.

Lower back pain affects millions of people worldwide. Research suggests that improving core stability may help reduce pain, improve movement control, and lower the risk of recurrent back injuries.

Do Core Exercises Help Lower Back Pain?

The lower back consists of five lumbar vertebrae supported by discs, ligaments, and muscles. Although this region allows substantial movement, it has limited bony stability. As a result, the surrounding muscles play a critical role in protecting the spine.

Deep stabilising muscles, including the transversus abdominis, multifidus, pelvic floor, and diaphragm, work together to maintain spinal control. These muscles activate automatically during normal movement when functioning well.

The Link Between Core Muscles and Back Pain

Research has demonstrated a strong relationship between lower back pain and delayed activation of key stabilising muscles. One important muscle, the transversus abdominis (TA), often shows delayed or reduced activation in people with persistent back pain.

In many cases, this muscle does not automatically return to normal function once pain settles. This can leave the spine vulnerable to repeated episodes of pain unless stability training is performed.

Why Core Stability Matters

Targeted core stability exercises help restore coordinated muscle activity around the spine. When these muscles work together effectively they:

  • Improve spinal stability
  • Reduce strain on joints and discs
  • Improve movement efficiency
  • Reduce the risk of recurrent lower back pain
  • Support athletic performance including strength, balance, and agility

These exercises usually focus on low-load muscle activation before progressing to functional strength and sport-specific movements. Many people also benefit from combining guided exercise with education and a gradual return to normal activity.

Seeking Professional Advice

If you experience persistent or recurrent back pain, a physiotherapist can assess your spinal control and movement patterns. They can then guide you through a structured rehabilitation program designed to activate and strengthen the appropriate muscles.

A personalised exercise program helps you activate the correct muscles while avoiding movements that may aggravate your symptoms. You can also read more about lower back pain and core stability training to learn how these strategies fit into a broader recovery plan.

Frequently Asked Questions

Do core exercises help lower back pain?

Core exercises can help reduce lower back pain by strengthening the muscles that support the spine. The deep stabilising muscles of the abdomen and back improve spinal control and reduce stress on the lumbar vertebrae, which may decrease pain and reduce the risk of recurrent back injuries. Learn more about core stability training.

Which core muscles support the lower back?

Several deep muscles support the lower back including the transversus abdominis, multifidus, pelvic floor muscles, and diaphragm. These muscles work together to stabilise the spine and pelvis during movement and everyday activities.

Why does weak core stability contribute to back pain?

Weak or poorly coordinated core muscles can lead to reduced spinal stability. When the stabilising muscles do not activate effectively, other spinal structures such as joints, discs, and ligaments may experience increased stress, which can contribute to lower back pain.

Should I see a physiotherapist for core exercises and back pain?

A physiotherapist can assess your spinal movement, muscle activation, and overall posture. They can then prescribe a tailored core stability exercise program that gradually improves strength, control, and function while avoiding movements that may aggravate your symptoms.

What to Do?

If you have lower back pain, early assessment and targeted rehabilitation can help reduce symptoms and improve spinal function. A physiotherapist can assess your condition and develop a progressive core stability program suited to your needs.

PhysioWorks physiotherapists regularly assess and treat spinal conditions and can guide you through safe and effective core stability exercises.

What Are the Best Core Exercises?

Front plank with physiotherapy guidance

The best core exercises are the ones that retrain your deep stabilising muscles before you move to harder drills. Good core training may improve spinal support, trunk control, and lower back protection. It also works best when matched to your symptoms, technique, and current strength level rather than copied from a generic fitness program.

If you are looking into this because of poor control, repeated flare-ups, or lower back pain, it helps to begin with accurate muscle retraining instead of advanced abdominal work. Many people do better when guided by a physiotherapist, especially if faulty movement patterns or repeated pain episodes are already present.

Quick Guide

  • Start with deep core activation before harder exercises.
  • Technique matters more than intensity early on.
  • Progress too quickly, and you may overload your spine.
  • A physiotherapist can help match exercises to your pain, control, and goals.

What Are the Best Core Exercises?

The best core exercises usually start with low-load activation of the deep core stability muscles, including the transverse abdominis, multifidus, diaphragm, and pelvic floor. These muscles act like an internal support system for your spine. Once they are working well, you can safely progress to more functional exercises such as bridging, bird dog, side plank progressions, and controlled standing balance work.

Why do deep core muscles matter?

Your deep core muscles help provide segmental support to the spine and assist with trunk control during lifting, walking, running, and sport. When they are not working well, your body often compensates by overusing the outer abdominal muscles, hip flexors, or back extensors. This pattern may contribute to repeated back pain, poor exercise tolerance, and reduced control during activity.

If you want more detail on this system, read the deep core muscles guide. You can also browse the broader back pain hub.

How do you start core exercises safely?

You should start with exercises that teach correct activation rather than fatigue. That often means practising breathing control, abdominal drawing-in, pelvic floor co-contraction, and gentle limb movement while maintaining trunk stability.

One useful progression tool is real-time ultrasound physiotherapy.

Helpful tip

A core exercise is only useful if you can control your breathing, pelvis, and spine while doing it.

What Exercise Ball Size Should I Use?

physiotherapist checking exercise ball size with seated knee and hip alignment

Correct exercise ball size keeps your hips slightly higher than your knees.

The right exercise ball size depends mainly on your height, leg length and how you plan to use it. Most adults suit a 55 cm or 65 cm ball. When seated, your feet should stay flat and your hips should sit slightly higher than your knees.

Choosing the correct exercise ball size can improve comfort, posture and control during sitting, balance work and core stability training. If you use a ball for back exercises or desk sitting, fit matters more than the label on the box.

Quick Exercise Ball Size Guide

  • 137–152 cm → 45 cm ball
  • 155–173 cm → 55 cm ball
  • 175–188 cm → 65 cm ball
  • 190–200 cm → 75 cm ball
  • 200 cm+ → 85 cm ball

How Do You Choose the Correct Exercise Ball Size?

Match your height to the ball diameter, then test your seated position. Your knees should sit just below hip height, your feet should stay flat, and your spine should feel relaxed rather than slumped.

If you are between sizes, choose the larger ball for sitting or workstation use. Choose the smaller ball for controlled exercise, balance drills or early-stage back exercises.

Exercise Ball Size Chart

Ball Diameter Recommended Height Common Use
45 cm 137–152 cm Smaller users / rehab
55 cm 155–173 cm Most shorter to average users
65 cm 175–188 cm Most average to taller users
75 cm 190–200 cm Tall users / sitting
85 cm 200 cm+ Very tall users

Before You Buy: Quick Checklist

  • ✔ Check your height against the size chart
  • ✔ Sit on the ball before regular use where possible
  • ✔ Confirm hips sit slightly above knees
  • ✔ Choose larger for sitting and smaller for controlled exercise
  • ✔ Inflate the ball firmly, without making it hard or unstable
ball chair height should be at least the height of your your thigh when seated.

Check seated knee height to confirm your ideal ball size.

Should I Use a Bigger or Smaller Exercise Ball?

Use a bigger exercise ball if your hips drop below your knees when sitting. Use a smaller ball if you need better control during exercise, especially for balance, beginner core work or gentle movement after lower back pain.

Common Exercise Ball Size Mistakes

  • Choosing a ball that is too small for sitting
  • Using a soft or under-inflated ball
  • Ignoring leg length and desk height
  • Using one ball for every exercise
  • Sitting on a ball for too long without posture breaks

Physio Tips for Safe Exercise Ball Use

Start with short sessions. Keep both feet flat, move slowly, and use the ball on a non-slip surface. If you feel unstable, dizzy, sore or unsafe, stop and use a more supported option.

Exercise balls may suit gentle back pain exercises, posture work and balance training when used well. However, they are not ideal for every person or every stage of recovery.

Choose the Right Exercise Ball

Use the guide above to select your likely size, then choose a ball that suits your goal. A better fit can make sitting, balance work and controlled exercise feel safer and easier.

What to Do Next

Most adults suit either a 55 cm or 65 cm exercise ball. If your hips sit below your knees, move up a size. If you cannot control the ball during exercise, move down a size or use a more stable option.

If you plan to use a ball for pain, rehab, posture or workstation support, a physiotherapist can help match the ball size to your body, goals and exercise program.

Exercise Ball Size FAQs

What size exercise ball should I use for my height?

Most people between 155–173 cm use a 55 cm exercise ball. People between 175–188 cm usually suit a 65 cm ball. Taller users may need a 75 cm or 85 cm ball, depending on leg length and how they plan to use it.

How do I know if my exercise ball fits?

Sit on the ball with your feet flat on the floor. Your hips should sit slightly higher than your knees, and your spine should feel upright and relaxed. If your knees sit higher than your hips, the ball is probably too small.

Should I go bigger or smaller with an exercise ball?

Go bigger if you are using the ball for sitting, especially at a desk. Go smaller if you need more control during exercise. Between sizes, your purpose matters: sitting needs height, while exercise often needs stability and control.

Can an exercise ball help posture?

An exercise ball may help posture by encouraging upright sitting and gentle core activity. However, it should not replace regular movement breaks, workstation setup or strength work. For desk comfort, also consider a full ergonomic workstation assessment.

Can I use an exercise ball for back pain?

Some people use an exercise ball for gentle movement, core control and supported back exercises. However, back pain has many causes. If pain worsens, spreads into your leg, or affects daily function, seek guidance before progressing exercises.

How firm should an exercise ball be?

The ball should feel firm but still give slightly when you sit on it. If it collapses heavily under your weight, it may be under-inflated or too small. Always follow the manufacturer’s inflation and safety instructions.

When should I avoid using an exercise ball?

Avoid using an exercise ball if you feel unsafe, dizzy, unstable or unable to control your balance. You should also seek advice before using one after surgery, a recent injury, a fall, or significant back or pelvic pain.

Is an exercise ball better than a chair?

An exercise ball is not automatically better than a chair. It can be useful for short posture or movement breaks, but long sitting still needs variation. For desk use, alternate between a supportive chair, standing, walking breaks and targeted exercise.
