Deep Core Exercises for Chronic Low Back Pain

The deep core supports the lumbar spine like an active brace, comprising the transversus abdominis, multifidus, diaphragm, pelvic floor and hip muscles. For chronic low back pain, specialists commonly focus on stability, motor control and a neutral spine, as this type of training improves function and may lessen pain in cases of non-specific low back pain.

Why is the deep core more important than traditional abdominal exercises?

Traditional abdominal exercises involve substantial trunk flexion, but they do not always teach the spine to remain stable during everyday activities. Stabilisation exercises, by contrast, condition the body to resist rotation, excessive extension and pelvic drop.

This control matters because the lower back is placed under strain when it has to compensate for weakness in the deep abdominal muscles, glutes and muscles surrounding the pelvis. The aim is not to complete a high number of quick repetitions, but to maintain breathing, alignment and gentle tension without stiffening the body.

How do you perform a dead bug to activate the deep abdominal muscles?

The dead bug is among the safest movements to begin with, as it is performed lying down, protects the lower back and involves no impact. It engages the transversus abdominis and deep stabilisers while the arms and legs move without allowing the pelvis to rock.

• Lie on your back with your knees bent at 90 degrees and your arms reaching towards the ceiling.
• Breathe out and engage your abdominal muscles as though you were fastening a zip below your navel.
• Slowly straighten one leg and the opposite arm, without arching your lower back.
• Return to the starting position, then repeat on the other side.
• Start with 2 sets of 6 to 8 repetitions on each side.

Why does the bird dog stabilise the lower back?

The bird dog works the multifidus, glutes, deep abdominal muscles and shoulder-blade control. It teaches the body to move an arm and leg without rotating the torso, precisely the kind of stability the spine needs when walking, carrying a rucksack, lifting objects or climbing stairs.

Position yourself on all fours, with your hands beneath your shoulders and knees beneath your hips. Reach one leg straight behind you and the opposite arm forwards, keeping the pelvis parallel to the floor; hold for 3 seconds, then return. Complete 2 sets of 6 to 10 repetitions on each side, without lifting the leg above hip level.

How does the side plank protect the spine?

The side plank strengthens the obliques, quadratus lumborum, gluteus medius and the trunk’s lateral stabilisers. These muscles stop the pelvis from “dropping” to one side, which is particularly relevant for people who experience lower-back discomfort during long walks, gentle running or prolonged standing.

• Begin with the knee-supported version, resting your forearm on the floor.
• Keep your elbow directly below your shoulder and your neck in line.
• Lift your hips until you form a straight line from your shoulders to your knees.
• Hold for 10 to 20 seconds, breathing without holding your breath.
• Perform 2 to 3 repetitions on each side, gradually extending the hold.

Progression should relieve symptoms, not cause more pain

For chronic low back pain, the ideal frequency is generally 3 to 5 times a week, in brief sessions lasting 10 to 15 minutes. Begin with the dead bug, bird dog and knee-supported side plank; then increase repetitions, holding time or leverage, but never all of them at once.

The spine responds better to consistent input than aggressive workouts. If pain travels down the leg, weakness, numbness, fever, a recent fall or progressively worsening symptoms occur, the safest option is to seek professional assessment before continuing with the exercises.
