How to Master The Kettlebell Swing: 3 Common Mistakes to Avoid

Why Kettlebell Swing Form Matters

The kettlebell swing is a powerful, explosive movement that builds strength in the posterior chain — especially the glutes, hamstrings, and core. But when performed incorrectly, it can place unnecessary stress on the lower back, knees, and even the neck. Whether you're new to CrossFit or a seasoned athlete, dialing in your technique is key to avoiding injury and maximizing performance.

Mistake #1: Squatting Instead of Hip Hinging

One of the most common mistakes in the kettlebell swing is excessive knee bend during the catch phase. This turns the movement into more of a squat rather than a hinge.

Fix it: Focus on pushing your hips back like you're trying to close a car door with your butt. Your knees should only bend slightly — around 10 to 20 degrees — while the majority of the motion comes from the hips. This helps load the glutes and hamstrings properly and protects your knees.

Mistake #2: Overarching the Lower Back

Another common fault is excessive arching of the lumbar spine at the top of the swing. This often happens when athletes try to "extend" too far through their back instead of finishing tall through the hips.

Fix it: Keep your core engaged throughout the swing. At the top, think "ribs down, glutes tight." Your spine should be in a neutral position, not hyperextended. This cue protects the lumbar spine during high-rep sets.

Mistake #3: Looking Up at the Ceiling

Some athletes make the mistake of keeping their head up and eyes fixed on the ceiling during the swing. While it might feel natural at first, this places strain on the neck, especially under load.

Fix it: Maintain a neutral head and neck position. Let your eyes follow the kettlebell — especially during the downswing. This alignment reduces cervical spine stress and promotes safer, more fluid movement.

Final Thoughts

Perfecting your kettlebell swing form doesn’t just make you a better athlete — it helps you train pain-free for the long haul. Whether you're doing kettlebell swings in WODs, strength circuits, or as a conditioning tool, mastering the hip hinge movement and avoiding these three common mistakes is essential.
