- Beginner
- Compound

This mobility exercise uses a massage ball against a wall to release tension in the erector spinae and obliques through a diagonal rolling pattern. It improves spinal mobility and alleviates lower back tightness by targeting myofascial trigger points in the lumbar region.

Setup
- Stand with your back to a wall and place a small massage ball (or tennis ball) between the wall and your lower back, positioned just to one side of your spine.
- Step your feet forward about 12 inches from the wall and keep your feet hip-width apart with a slight bend in your knees.
- Lean your body weight back against the ball to secure it in place against the lumbar muscles.
How to do it
- Slowly bend your knees to squat down while simultaneously shifting your hips laterally, causing the ball to roll diagonally upward and outward toward your lower ribs.
- Reverse the movement by straightening your legs and shifting your hips back to the center, rolling the ball back to the starting position near the top of the pelvis.
- Inhale as you begin the movement and exhale as you apply pressure into the ball during the roll.
- Perform all repetitions on one side of the spine before switching the ball to the opposite side.
Form checklist
- Keep the ball on the fleshy muscle tissue and avoid rolling directly over the spinal vertebrae.
- Maintain a neutral spine throughout the movement; do not excessively arch or round your back.
- Move at a slow, controlled tempo to ensure the ball doesn't slip out of place.
- Keep your shoulders relaxed and your gaze forward to avoid neck strain.
Pro tips
- When you hit a particularly tender spot (trigger point), pause for 10-15 seconds and take deep breaths to allow the muscle to release.
- Focus on the 'mind-muscle connection' by visualizing the muscle fibers lengthening as the ball passes over them.
Make it harder
- Use a firmer ball, such as a lacrosse ball, to increase the intensity of the myofascial release.
- Cross your arms over your chest and lean more of your body weight into the wall to deepen the pressure.
