Side Plank
Supported on one forearm and the side of the foot, you hold a lateral body bridge that trains the quadratus lumborum, lateral hip, and obliques to prevent lateral spine bending. The side plank is one of Stuart McGill's Big 3 for evidence-based lower back rehabilitation.

How to do it
- 1
1. Lie on your side with your forearm on the ground, elbow directly beneath your shoulder, and legs extended.
- 2
2. Stack your feet or place one foot in front of the other for stability, keeping your body in a straight line from head to heels.
- 3
3. Engage your core and lift your hips off the ground, creating a lateral bridge supported by your forearm and foot.
- 4
4. Maintain a neutral spine—avoid rotating your torso forward or backward, and keep your top shoulder stacked above your bottom shoulder.
- 5
5. Hold this position while breathing steadily, ensuring your hips stay elevated and aligned with your shoulders and ankles.
- 6
6. Lower your hips back down gently and repeat on the other side.
Benefits
- Strengthens the quadratus lumborum and lateral core muscles to stabilize the spine and prevent lateral flexion during daily movement.
- Reduces lower back pain by building the deep stabilizer muscles that support spinal alignment and reduce compensatory stress.
- Improves postural control and balance by training the hip abductors and obliques to maintain upright posture during standing and walking.
Common mistakes
- Allowing your hips to sag or rotate, breaking the straight-line alignment and reducing core engagement effectiveness.
- Positioning your elbow too far forward or backward relative to your shoulder, which shifts load away from the core and strains the shoulder.
- Holding your breath instead of breathing steadily, which increases tension and reduces the duration you can maintain proper form.
