3 Core Exercises to Bulletproof Your Spine

When people hear "core workout," they often think of six-pack abs and endless crunches. But from a performance and injury prevention standpoint, the true purpose of the core is not to create motion, but to resist it.

A strong, stable core acts like a natural weightlifting belt, protecting your spine from the dangerous shearing forces that lead to disc injuries and chronic pain. At Windmill Health Center, I prescribe these three exercises more than any others to build a truly resilient core.

1. The Bird-Dog

This exercise is deceptively simple but incredibly effective at teaching your core to resist rotation (anti-rotation training).

• How to do it: Start on all fours with your hands under shoulders and knees under hips. Slowly extend your right arm straight forward and your left leg straight back, keeping your hips and shoulders perfectly level. Imagine you have a glass of water on your lower back that you can't spill.
• Key focus: No rotation in the hips or shoulders. Keep your back flat.
• Goal: 10-12 slow, controlled reps per side. Hold each rep for 2-3 seconds.

2. The Dead Bug

The dead bug is the ultimate exercise for learning to keep your lower back stable while your limbs are in motion—exactly what happens in real life.

• How to do it: Lie on your back with your arms extended towards the ceiling and your knees bent at 90 degrees (tabletop position). Slowly lower your right arm and left leg towards the floor, stopping just before they touch. Crucially, your lower back must stay pressed firmly into the ground throughout.
• Key focus: If your lower back arches off the floor, you've gone too far. Reduce the range.
• Goal: 8-10 reps per side, moving slowly and with control.

3. The Side Plank

This exercise targets the quadratus lumborum (QL) and obliques, key muscles for lateral stability and preventing side-bending injuries.

• How to do it: Lie on your side, propped up on one elbow directly under your shoulder, with your feet stacked. Lift your hips off the ground, creating a straight line from your head to your feet. Don't let your hips sag or pike up.
• Modification: If this is too challenging, start with your knees bent at 90 degrees.
• Goal: Hold for 30-45 seconds per side. Work up to 60 seconds.

Why These Three?

These exercises train the three primary functions of the core:

1. Anti-rotation (Bird-Dog)
2. Anti-extension (Dead Bug)
3. Anti-lateral flexion (Side Plank)

By incorporating these three movements into your routine 3-4 times per week, you move beyond simple aesthetics and start building a functionally strong core that will serve you for years to come.
