The Hidden Science of Kettlebell Swings: Part 2

Part 2 breaks down the role of core stabilizers, spinal health, and the key mechanics that make kettlebell swings so effective for injury prevention.

Most people think of kettlebell swings as a strength and power exercise, but there’s a lot more going on under the surface.

In this video, we’re diving into the science behind how kettlebell swings recruit key core stabilizers, support spinal health, and build a resilient posterior chain.

We’ll break down:

✔️ The role of trunk stabilizers like the multifidus and erector spinae
✔️ How hamstring and glute activation support a strong, neutral spine
✔️ The difference between two-hand and one-arm swings—and how they impact spinal rotation
✔️ Why proper hinge mechanics are critical for injury prevention

Understanding these mechanics will help you refine your technique, reduce injury risk, and get more out of every swing.

🔔 Stay tuned for the next video, where we explore kettlebell swings for rehab and prehab!
